AMD's 785G Chipset with IGP Radeon HD 4200 Graphics

AMD 785G Chipset


While not as sexy as writing GPU at the high end with hundreds of stream processors, a billion transistors or more, and the GDDR5 memory last Blazing fast integrated graphics solutions are what the power of the majority of PCs in use today. According to the latest figures from industry research firm Jon Peddie Research, Intel compared to controls by 50% of the market for graphics cards together in spite of the absence of a discrete graphics card of their own to sell public instead of by all the graphics has come from programming of integrated graphics chipsets.



Each month, Intel usually tens of millions of G45, G43, G41, GMA X4500 and GMA X3100 integrated graphics chipsets to customers around the world. The IGP (integrated graphics processors) are then sold at $ 300 and $ 400 desktops and laptops found from computer manufacturers like HP and Dell.

AMD wants the most from this action. Seeing the huge volumes of IGP Intel moves each month, who can blame them? When they bought ATI back in 2006, they cited the fusion of CPU and GPU as a key to the purchase, but in the short term, they also expressed the hope that ATI chipsets and the PGI would score new design wins with OEMs wary of buying processors from one source and PGI another (usually NVIDIA), and possibly help to take some share from Intel.

Unfortunately for AMD, despite a good range of products, things have not quite panned as originally planned.

Intel has actually been first to market with an IGP that supported DirectX 10 graphics. Their series of chipsets Bearlake G3X beat AMD to the punch by several months, scoring design wins AMD had hoped, despite the fact that DX10 offers first AMD 780G chipset, delivered the best 3D graphics performance than that of Intel G35.

780G chipset is remarkable for its time. Thank you to a die shrink, ATI was essentially able to integrate their existing RV620 GPU found in their Radeon 3450/3470 value and put it in the 780G chipset itself. ATI has had to strike the clock speeds up a bit to fit within their power / thermal balance, but otherwise, it is basically the same GPU.

Hybrid Graphics has been the factor that has really put on the map 780G though. Like ATI's CrossFire technology, Hybrid Graphics, you could pair a discrete graphics card Radeon 3450 integrated graphics with heart in the IGP to increase by nearly 2X performance in games. It was the first mutli-GPU technology has been found in an IGP of any manufacturer (NVIDIA followed with their own solutions later).

Now ATI and AMD are back with a successor to 780g. Internally known as 785G, the world outside AMD will market it as the Radeon HD 4200 and 785G chipset with Radeon HD 4200 graphics. The Radeon HD 4200 suggests that this classification is a new game based on a derivative RV7xx heart Radeon 4000, but this designation implies 785G chipset is improving gradually over the platform 780g. Which one is it? Let's find out!

785G Chipset Features

This is latest chipset ATI Radeon 3000 is a serial product, as the name implies 785G or is it part of the series Radeon 4000? It's a bit of both, but we would certainly call it an extension of the architecture 780G instead of a part RV7xx news.

Basically the graphics architecture of the heart itself is quite similar to the Radeon GPU found in graphics 780G 3200. You have the same 40 stream processors with 4 texture units and 4 ROPs as the 780G, the same ability to send up to 512 MB of system RAM, and the same clock speed of 500 MHz core.



This is probably a disappointment for those of you who expected a real successor next-generation architecture based RV7xx success of ATI. The Radeon HD 4350 to sport eg twice the stream processors - 80 - with eight texture units and 4 ROPs. With the 785G chipset based on the same manufacturing process 55 nm as 780G, ATI could not put a price affordable the 4350's 242 million transistors within their transistor budget for 785G.

As such, 785G Hybrid Graphics support is limited to the Radeon 3400 Series, like its predecessor, the 780G.

Hybrid Graphics will not be a selling point this time though. Found Radeon 3400 is increasingly difficult. Newegg for example, that three lists Radeon 3450 boards in stock right now, and two of them are more expensive than the Radeon 4350. Not that it would still matter, as a Radeon HD 4350 graphics card will run faster than the 780G + Radeon 3450 Graphics hybrid combination. Radeon 4350 cards start for only $ 3 more than the cheapest 3450 card on Newegg.

We ran with the banks of the 785G integrated graphics and discrete Radeon 4350 graphics card marks for this product so you can see how the two graphics solutions Fare against each other.

ATI has added some new ingredients to the 785G IGP that are not found in 780G though. For starters, the chip now fully supports DirectX 10.1, while the 780G is limited to supporting DirectX 10.0. DirectX 10.1 is a very gradual improvement over DirectX 10 though, and considering that the income-generating projects are not graphics processing power to run DX10 titles anyway it is probably more a function of Control for OEM brand than anything else.



More notable additions ATI integrated chipset 785G HDMI 1.3 Support (780G was limited to HDMI 1.2) and RV7xx features like support for hardware video transcoding on the GPU rather than CPU Stream uses ATI and ATI Unified Video Decoder 2 (UVD 2), these two features were introduced with the 4000 series GPU Radeon last year. 785G can also multi-channel LPCM audio output over HDMI as well.

AMD has confirmed that the multi-channel LPCM audio over HDMI is not supported by 785G, 780G, 785G chipset, as is limited to 2 channels only.

If you remember, UVD 2 includes support for hardware accelerated image in the image to watch Blu-ray and video enhancement features such as dynamic contrast, HD Color Enhancer (including flesh and the brilliance of tone colors) and post-processing effects such as noise reduction, deinterlacing and HD with the HD, which is only supported when dynamic contrast is turned off.

So essentially with 785G could say that the merger with ATI's graphics power of RV620 with the video capabilities of the RV730. This description is not entirely true, but it gives you a quick overview of the performance of the IGP differs from previous issues ATI. The Southern Bridge again unchanged, with series SB7xx AMD chips supported. This is the same chip already used on current platforms 7-series.

As always when spec’ing out our upgrade builds, we start with the GPU we want to go with followed closely by the CPU, and then build the rest of the system around those two core components until everything works within the intended budget.

Right from the get go we knew we wanted to opt for ATI’s Radeon 4850 GPU. Launched over a year ago, the Radeon 4850 is a tremendous performer that can handle most games at high quality settings, even with antialiasing and anisotropic filtering enabled. We prefer the Radeon 4850 over the GeForce GTS 250 at this time due to its lower price tag and better performance under 8xAA. Yes, in older games you can crank the AA all the way up to 8xMSAA and the 4850 still delivers very playable performance. This is particularly feasible at the 1600x1200 (or 1680x1050) resolution our entry level PC would be gaming at. We chose the ASUS card in particular because of its low price, dual DVIs, and dual-slot cooler. If you’re willing to deal with mail-in rebates, MSI’s R4850-2D512-OC would be our top choice. It’s factory OC’ed, and has beefier 4+1 phase power, along with MSI’s seaweed blade fan.

As an added bonus, it’s actually slightly cheaper than the ASUS card after rebate: $89.99.

The next component, AMD’s Phenom II X2 550 Black Edition was another no-brainer. As its name implies, the Phenom II X2 550 Black Edition is based on the exact same 45-nm Deneb core AMD uses in their latest Phenom II processors. The only difference is AMD activates two processing cores, leaving two cores disabled. Because it’s based on the same core as AMD’s other Phenom II parts, the same key architecture features carry over unchanged. The chip features 64KB of L1 cache per core for data and instructions (256KB L1 total) and 512KB of L2 cache per core for a grand total of 1MB of L2 cache active on the processor. The L3 cache carries over unchanged, with the Phenom II X2 550 Black Edition sporting 6MB of L3 cache shared amongst the processors two cores.

AMD clocks the chip at 3.1GHz, with the chip featuring a 15.5x multiplier. Keep in mind that as a Black Edition CPU, the multiplier is unlocked and can be adjusted to whatever setting you wish when OC’ing.

For the motherboard, we chose the Gigabyte GA-MA770T-UD3P. We reviewed this motherboard a few weeks ago and found it delivered solid performance with a robust BIOS and good feature set.

G.SKILL’s DDR3-1333 memory kit is the cheapest available on Newegg right now. G.SKILL also offers DDR3-1600 memory modules that are priced similarly, but we opted for the 1333MHz modules due to their lower latency.

NZXT’s Beta case is pretty popular among enthusiasts on a budget right now. The case boasts a perfect score on Newegg and has room for up to four 120mm case fans. It’s also offered with a $10 mail-in rebate right now, bringing the total price down to $39.99 if you don’t mind waiting for your rebate check to arrive.

To go alongside the Beta case, we chose a slightly less powerful PSU from Cooler Master due to its better power ratings on the 3.3V and 5V rails. Note that ATI officially recommends a minimum of a 450W PSU for the 4850, so we’re just getting by in this regard, but again, the 460W Cooler Master actually has better specs than comparably-priced 500W PSUs. We acknowledge that this is one of the key weaknesses of our system, so if you can afford to spend a little more on this component, we’d highly recommend it. A 600W PSU would be a good starting point.

Alternatives

In terms of the CPU and GPU, we wouldn’t recommend any other alternatives at this price point. However, as we mentioned you could save a little money by opting for the MSI 4850 card if you’re willing to deal with rebates.

Another big area you could save a little money on is switching from the AM3 platform we used, and reverting down to AM2+. Gigabyte’ GA-MA770-UD3 is actually $5 cheaper than the GA-MA770T. You’d also be able to save on the DDR2 memory. G.SKILL offers 4GB DDR2-800 kits for as low as $46.99.

In exchange, you could then opt for a more powerful PSU or get a good CPU cooler.

We actually debated long and hard about making this AM2+ setup the primary $500 AMD build, but ultimately opted for the newer AM3 platform. As DDR3 prices continue to fall, the AM2+ platform will be phased out. We figured we may as well go ahead and get on the boat.

AMD Release Packs 6-Core Opteron

AMD Opteron

Advanced Micro Devices has released a version of the 6-Core low-power Opteron processor in time for VMworld virtualization key that opens Monday.

The 6-Core AMD Opteron EE consume 40 watts and is designed for 2P servers, one of the most popular in the area of virtualized servers. The chip costs $ 989 and will begin shipping on Monday.

Maintaining the thermal envelope identical to the previous generation of chips, the Opteron 2419 EE 1.8GHz, compared to 2.0 GHz clock speed of the "Generation Opteron Shanghai. AMD claims that the third EA 2419 provides better performance than the EA 2377, four core chip whose nuclei have been clocked at 2.3GHz, who also ran against a 40-watt thermal envelope.

The new 6-core chip also contains the AMD-V virtualization technology, including AMD mechanisms power management P. VMworld, the show managed by the virtualization company VMware.

AMD also said that energy for a fully populated 42U rack would be 9.2 kilowatts using 6-core Opteron 2425 SE, item 55-W. The replacement of these chips with EE 2419, would require 7.5 kilowatts, or about 18 percent energy savings.

According to IDC data cited by Brent Kerby, a product manager for the chip, about 82 percent of the cloud and Web servers use only about half the processing power available at a given moment. "With more cores, you have more space for moments ... Web pips strikes a fair amount of support, if you want, "said Kerby. "The region most affected, energy consumption, set in the power range of 40 watts, and even above the threshold of power."

The bottom line? More power in a rack (or compute density) while maintaining low power range of 40 watts, Kerby said.

The new Opteron chip also uses DDR-2 memory, which AMD claims will save approximately $ 1,000 per server, as opposed to DDR-3 more expensive memory.

AMD Outlined its Upcoming 12-core Server Processor

At Hot Chips, last week, AMD unveiled details about the upcoming 12-core "Magny-Cours" processor, which it hopes will help it remain competitive in the game server. In 2010, AMD 45 nm SOI, Magny-Cours uses the same basic Core micro architecture as the current Shanghai quad-processor database server, so if there is no improvement in performance by wire will come from better system design.

The idea of Magny-Cours is simple: Take two to six processors at the heart of Istanbul, they clock down a little on the power to reduce and work in a multi-chip module (MCM), so they can take in a socket. Using an MCA, AMD will be able to fit 12 cores in the same power envelope as heat and Istanbul.

Doing this work requires a little compromise, and one of them is the MCM itself. AMD had previously ridiculed for using an MCM first Intel dual-core effort, the Pentium 4-based Smithfield, not "true" dual-core. They repeated the charge in the first quad-core Intel, which is also an MCA. But with per-core Nehalem cleaning absolute performance, which AMD is eager to maintain a credible presence server, and part of that crowd is the determination of strategy of MCA who had mocked.

For reasons of system architecture, AMD MCM picture is somewhat more complicated than was Intel, Istanbul, because each chip has its own on-die dual-channel DDR3 memory controller, and four HyperTransport links. Obviously you can not support any full-chip interconnect bandwidth through a single connection, so AMD had to cut some ties.

The company has four overall MCM design HT 2.0 ports (two per chip) and four DDR3 memory ports (two per chip) on each MCM. For each chip, a link is x16 and one x8 is different. The two chips are connected in the module x16 link exc.

Even with four HT links and four memory channels for the MCM Fed to maintain the 12 cores is a lot to pack into an electrical outlet, bandwidth and hunger is a concern. To help alleviate the bandwidth pressure on AMD Istanbul assistance of a clever balance in the form of HT, and this assessment will be carried forward to Magny-Cours, where even more necessary.

One of the major challenges in the design of multiprocessor system is maintained caches of different processors in sync with the other solutions to this problem to a certain degree of communication between processors, and "snoop" bus traffic Dining the precious bandwidth. The solution adopted in Istanbul and Magny-Cours AMD involves the destruction of 6 MB of cache 1 MB per chip to store the contents of a directory caches of other chips, so by consulting the local telephone directory each chip can prevent a broadcaster major growing number of requests for traffic to snoop other chips.

The reason is that hormone Assist workspace is relatively cheap compared to tube and bus bandwidth, so that every trick you trade some transistors on die for a boost in bandwidth real world bus is a victory. In fact the basic idea behind all kinds of caches, and directory HT Assist is really just another type of cache. Bandwidth per socket will always be expensive if the number of cores in each socket increases, and so we see the plans multi swing back to the state of affairs at the end of the era single-core, ie where a transformer, which is usually a large proportion of very fast memory with a number of blocks to load attached.

After Magny-Cours, AMD plans to continue to raise the number of cores per socket, while maintaining backward compatibility with Magny-Cours and taken to Istanbul, power and thermals.

AMD unveils Phenom II architecture for newer gaming focus

AMD was the start of the conference with the official debut of the Phenom II, his first major processor 45 nanometers. The upgrade is based on the same basis "Shanghai" Opteron recent architecture and offers a speed of about 20 percent during the last best pulse 2.6GHz chip through changes associated with an optimized design with more detailed instructions processed per clock cycle, 4 MB cache extra total, and support for DDR3 memory at 1333MHz Intel competing systems. The design is now much more tolerant of the high clock speed and will continue to 3 GHz in stock trim.

Reflecting a new focus Thursday AMD is a new grouping, the usefulness of a simplified overclocking with its highest-end model, en tout a large number of options for higher speeds. The chip is capable of so much 4GHz based on the fan, the company claims. Exotic overclocking using liquid nitrogen to the system to 6GHz or more; Core i7 and material support from the older generations can not reach this point, because they physically limited by a cold bug "that prevents them fall below a certain temperature, according AMD representative Simon Solotko.

When asked why the system is Intel 3.2GHz despite room for faster clock speeds, the official statement that the need for the chip to run at regular specifications without problems. Yet it is widely seen by some observers that the move is a deliberate attempt to avoid any race clock Intel, which saw the two companies ramp rates up to their limit.

The design is also reported that more than 30 to 40 percent more power at peak load. despite its 125W ceiling, and the plan to work with a 790GX chipset motherboard (mainboard) as part of a platform combined nicknamed "Dragon". The new Union is not only a 3.6GHz or faster, faster Hyper Transport (interface) bus, but also for better integration of images that can be used in a way to stop the Hybrid CrossFire video dedicated to saving energy with lighter loads.

Taking design is compatible and works on many games in the series 780-use of DDR2 memory simply by applying a firmware update. AMD claims that users have the option to upgrade to new models and get 790GX performance DDR3 architecture and other changes without replacing the transformer.

AMD's first Phenom II chip is available today and the introduction of a 2.8GHz Phenom X4 II 920 to $ 235 in large lots for PC makers. The flagship model of 3Ghz 940 is locked for overclocking and costs $ 275 in similar quantities. Retail kits are likely to cost more.

The introduction of vital importance for AMD, which has difficulties to maintain its competitiveness with Intel and had to abandon its forecast for this year by 25 percent that Intel maintains a current leyden performance in both desktops and laptops. Phenom II should not only AMD's competitiveness in the implementation, but also to win on price, according Solotko a typical mother for the new equipment Gigabyte or any of its rivals will cost about $ 140, about half of the minimum cost of entry for a Core i7 motherboard(Mainboard).

Solotko rejects notions that Intel Hyperthreading, which can sometimes make use of two program threads on a single core, is always the best for the games it supports, rather than the platform in conjunction with the focus on the effectiveness of the core chips, and the use of the latest video cards support general computing, need to be in general.

"Throwing threads games will not solve the problem," he said, referring to Intel technology.

Best Values VGA Card For Games

The specifications of the graphics card and comments are great-that is, if you have the time to do research. But at the end of the day, what a player needs is the best graphics card within a certain budget.

Therefore, if you do not have the time to research the benchmarks or if you do not feel confident enough in his ability to pick the right board, fear not.

The Radeon HD 4850 X2 became commercially available right after last month’s article was published. The 4850 X2 is a tough card to peg, as its $370 street price is a bit more than the cost of two separate 4850 cards, which can retail for as low as $340. Having said that, the 4850 X2 is equipped with 2 GB of video RAM, while the 4850s with 1 GB of RAM start at $200 each from what we’ve seen. In addition, the 4850 X2 seems to be able to beat Nvidia’s more-expensive flagship GeForce GTX 280 by a small margin. With this in mind, we recommend the Radeon 4850 X2 for those of you with a $370 budget.

Otherwise, the news has been pretty quiet going into the holiday season. Prices keep falling and consumers can’t complain with all of these wonderfully-powerful cards hovering around the $100 mark.

AMD is on the verge of releasing its Catalyst 8.12 driver, which, once installed, should introduce marked performance increases in a number of newer games, as well as adding some new capabilities like a stream computing feature and video encoding acceleration to battle Nvidia’s recent "Badaboom" trial.

On the Nvidia side, we should soon see 55 nm versions of the G200 cards. These should use less power than Nvidia’s current 65 nm GeForce GTX 260/280 cards and make them more overclockable to boot. If this is the case, it’s a safe bet that they’d be ideal for a GeForce 280 GX2 card with two GPUs — just the kind of thing that Nvidia would love to manufacture in order to get the performance crown back from the Radeon HD 4870 X2.

Regardless of what the future holds, lower prices and more performance equal good times right now.

Some Notes About Our Recommendations

A few simple guidelines to keep in mind when reading this list:

  • This list is for gamers who want to get the most for their money. If you don’t play games, the cards on this list are more expensive than what you really need;
  • Prices and availability change on a daily basis. We can’t offer up-to-the-minute accurate pricing info, but we can list some good cards that you probably won’t regret buying at the price ranges we suggest;
  • The list is based on some of the best U.S. prices from online retailers. In other countries or at retail stores, your mileage will most certainly vary;
  • These are new card prices. No used or open box cards are in the list; they might be a good deal, but it’s outside the scope of what we’re trying to do.

Good 1440x900 performance in most games

ROPs: 8
Memory Bus: 128-bit
Core Speed MHz: 600
Memory Speed MHz: 500 (1000 effective)
DirectX / Shader Model DX 10.1 / SM 4.0

With the Radeon HD 4650’s price dropping to $60, we have a really attractive budget gaming option that takes us past the old budget 1280x1024 limitation. The 4650 is simply an underclocked Radeon 4670, which by now has a reputation as being a very fast mainstream card with low power requirements. Well, the 4650 requires even less power and offers very good gaming performance for the price.

The 4650 is also an exemplary choice for a home theater PC because it can accelerate even HD video without breaking a sweat, and since it’s a single-slot solution, the card won’t use up too much space in your HTPC.

Good 1600x1200 performance in most games

Radeon HD 4670 GDDR3
Codename: RV730

DirectX / Shader Model DX 10.1 / SM 4.0

The Radeon HD 4670 slaps previous-generation, high-end performance squarely in the jaw of mid-range pricing. With 320 shader processors, this card means business and will provide awesome 1600x1200 gaming. Compared to the 9600 GSO, its main advantage is a low-power requirement—the 4670 doesn’t need an external power cable, which for some upgraders is a really important feature.

GeForce 9600 GSO (aka GeForce 8800 GS)

Memory Speed MHz: 900 (1,800 effective)
DirectX / Shader Model DX 10 / SM 4.0

Previously a high-end card crippled and transformed into a high- to mid-range card, the release of the Radeon HD 4670 has forced the 9600 GSO to a lower price to remain competitive—which it does. It’s an excellent alternative to the 4670, as long as the buyer compares clock speeds and makes sure he or she has one of the desirable models (manufacturers seem to follow the reference speeds very loosely).

Good 1600x1200 performance in most games; 1920x1200 in most titles with some lowered detail

DirectX / Shader Model DX 10.1 / SM 4.0

The new Radeon HD 4830 finally gives AMD something to compete against the legendary GeForce 8800 GT (as well as its identical sibling, the 9800 GT). Just as the 8800 GT is a crippled 8800 GTS, the Radeon HD 4830 is a crippled 4850. Both cards are excellent, while one winning over the other depends on the game or the image-quality settings.

DirectX / Shader Model DX 10.1 / SM 4.0

The Radeon HD 4850 is the new people’s champion, instantly bringing yesterday’s $300 performance level down to the mainstream $160 price point. This card has a lot of potential when used on its own, and becomes a devastating force when paired with a second 4850 in a CrossFire configuration.

Memory Speed MHz: 900 (3,600 effective)
DirectX / Shader Model DX 10.1 / SM 4.0

The Radeon HD 4870 offers the same architecture that the 4850 series does, paired with its secret weapon: brand-new GDDR5 memory. This technology provides about twice as much throughput as the GDDR3 does, so its 900 MHz clock speed is comparable to a 3,600 MHz effective memory speed. This edge allows the 4870 to up the ante and offer a very compelling level of performance for the price, even competing with the more-expensive GTX 280 in some titles.

The GeForce GTX 260 offers a compelling level of performance now that its price has been reduced to $220, allowing it to trade blows with the Radeon HD 4870 on its own turf. This is one of those situations where a buyer really should look at which card is best for the games he or she plans to play (although you really can’t go wrong with either card).

We designate the new version of the GeForce GTX 260 with a “+” symbol to differentiate it from its identically-named older sibling. Even though there is no official difference between the two cards, the new GTX 260+ has some very tangible performance increases over the original version. For example, the number of shaders have been increased from 192 to 216, which are within spitting distance of the GeForce GTX 280’s 240 shaders. ROPs have been increased from 64 to 72, once again approaching the GTX 280’s 80 ROPs.

The result is a card that performs almost as well as the expensive GeForce GTX 280, for much less money, and it even beats the GTX 280 when overclocked! You must carefully search for the GeForce GTX 260+ by looking hard at the specifications, but it is certainly worth the price premium over the original GTX 260.

It turns out that the Radeon 4870, when equipped with a whole gigabyte of GDDR5 RAM, can up the ante to compete against the GeForce GTX 260+ in some titles. As usual when it comes to these two tough competitors, it pays to look at the benchmarks and see which title you play more, as they tend to trade blows depending on the game.

In the 4850 CrossFire benchmarks we’ve seen so far, we’ve found that AMD has really learned to squeeze the performance out of its new cards. While a single performs in the same realm as the Radeon HD 4850 GeForce 9800 GTX+, two 4850s in CrossFire mode will beat the dual-GPU GeForce 9800 GX2—and even put the hurt on the more expensive GeForce GTX 280.

The 4850 X2 differentiates itself from a cheaper 4850 CrossFire setup with a full 2 GB of RAM, which usually allows this card to perform better than Nvidia’s flagship GeForce GTX 280 for less money. While the gains over two 4850s in a CrossFire setup might be minimal, those of you without a CrossFire-compatible motherboard will find the 4850 X2 more convenient—just make sure your case and power supply can accommodate the beast.

In this author’s opinion, with exponentially increasing prices over $370 offering smaller and smaller performance increases, we have a hard time recommending anything more expensive than two Radeon HD 4850s. While the 4870, GTX 260, and GTX 280 perform impressively in multiple-card configurations, there’s just not enough of a gain compared to a Radeon 4850 X2, unless you’re playing at resolutions beyond 1920x1200.

Then again, while we often recommend against purchasing any graphics card more than $370 from a value point of view, there are those of you for whom money might not be much of an object, who can afford a 30” LCD monitor and who require the best possible performance money can buy. For those of you, we recommend the $500 Radeon HD 4870 X2, the fastest video card on the planet.

Summary

There you have it folks: the best cards for the money this month. Now all that’s left to do is to find and purchase them, and we leave that part up to you. The best prices will almost certainly be found online, but sometimes large retail outlets might surprise you with a good sale.

Don’t worry too much about which brand you choose, because all of the cards out there stick pretty close to Nvidia’s and AMD’s reference designs. Just pay attention to price, warranty, and the manufacturer’s reputation for honoring the warranty if something goes wrong.

Also remember that the stores don’t follow this list. Things will change over the course of the month and you’ll probably have to adapt your buying strategy to deal with fluctuating prices. Good luck.

DSM - Small fanless control computer for POS/POI and digital signature applications

DSM - Small fanless control computer for POS/POI and digital signature applicationsWith its small dimensions of only 180mm x 180mm x 55mm, the PicoBox from DSM Computer, is seen as the perfect fanless control computer for POS/POI and digital signature applications. The PicoBox augments DSM's embedded systems product line with the high-performance NanoServers and the scalable BookSize PCs for ultra-compact applications, says the company.

The PicoBox is currently available in two variants. The first variant is the PicoBox C2 (96M1611L) model based on the low-POWER Intel Atom N270 processor with a clock frequency of 1.6GHz. The integrated Intel 82945GSE chipset with the Southbridge ICH7M also operates very energy-efficiently. Together they consume only approximately 4.5W. Despite the small power consumption, the Intel Graphics Media Accelerator 950VGA allows the PicoBox C2 to provide good graphic performance. A DVI output is provided as graphical interface.

The second variant is PicoBox C1 (96M1610L) based on the AMD Geode LX800 processor with 500MHz and the AMD CS5536 chip set with internal AMD 2D VGA controller. In contrast to the PicoBox C2, the display is attached using a VGA interface.

Both PicoBox variants offer a dual-LAN interface ideal for use as a client in network applications. Whereas the PicoBox C2 provides GigaBit LAN (2x 1000 Base T) connections, C1 provides two 10/100 Base TX interfaces. If required, WIRELESS LAN 802.11b/g is also supported. In addition to four USB 2.0 ports, two serial outputs and a PS/2 connection (PicoBox C2) or four serial outputs (PicoBox C1) are available. For specific customers, a separate interface panel allows additional external interfaces to be made available.

The high-quality PicoBox housing has space for a 2.5-inch hard disk (Ultra DMA/33/66/100). A USB 2.0 interface allows the external connection of a floppy or a CD/DVD-ROM drive. The CF socket permits the data storage to a Compact Flash.

An external 100VAC to 240VAC 45W power pack, an optional external 8VDC to 30VDC supply or a direct 12VDC input supplies power to the extremely compact embedded system. The operating temperature range is specified as 0C to +50C, says the company.

AMD pushes out three more triple-core chips

Chip maker targets gamers and digital content creators with desktop processors
Advanced Micro Devices Inc. today unveiled more triple-core processors, adding to several models released earlier this year.

The announcement comes amid Internet rumors that the chip maker may be announcing plans to spin off its manufacturing operations as soon as next week.

John Lau, senior semiconductor analyst and managing director of Jefferies & Co., said last week that AMD is looking to spin off its fabrication plants into a separate company funded by a Middle East consortium. The company, according to Lau, will handle AMD's manufacturing but will also be free to build chips for other companies.

An AMD spokesman last week said that the company would not respond to rumors.

Today, however, the AMD is focused on announcing its new desktop processors: the Phenom X3 8750 Black Edition, with a Clock Multiplier Control and tunable performance; and the energy-efficient Phenom X3 8450e and Phenom X3 8250e.

The chip maker noted in an e-mail to Computerworld that the chips are aimed at the gaming community and at digital content creators.

Dan Olds, principal analyst at Gabriel Consulting Group Inc., noted that while AMD's technology is still well behind that of rival Intel Corp., the triple cores are a welcome addition to the chips being offered.

"They do fill a slot in the market, providing a balance of price vs. power," Olds added. "They'll be speedy enough to handle demanding games and applications, but at a reasonable price."

AMD released its first triple-core chip in March, with three more available a month later. AMD released another one last month.
