Cray XK6 supercomputer smashes petaflop record, humbly calls itself a ‘general-purpose’ machine

Sure, IBM’s ten petaflop supercomputer may sound impressive, but Cray can do you five better — the outfit just announced the Cray XK6, an upgradable, hybrid supercomputing system capable of more than 50 petaflops of computational muscle. Powered by Cray’s Gemini interconnect, AMD Opteron 6200 processors, and NVIDIA Tesla 20-Series GPUs, the XK6 system blends x86 and GPU environments with the firm’s own flavor of Linux. The folks at Cray won’t resort to bragging, however — they’re humbly declaring the machine to be the first “general-purpose supercomputer based on GPU technology,” and not, as they put it, a stunt to place high on any Top 500 lists. Suggestive, aren’t they? Check out the unassuming press release after the break.

AMD announces new, more energy efficient Embedded G-Series APUs

AMD has just rolled out two new additions to its line of Embedded G-Series APUs, combining Fusion-based processing with reduced power consumption. Both the T40E and T40R rock the same 64-bit x86 Bobcat CPU cores and DirectX 11-capable GPUs we’ve already seen in previous G-Series incarnations, but AMD says the pair can operate using thirty-nine percent less power than its cousins. The single core T40R boasts a thermal design power (TDP) rating of just 5.5 watts, while the dual core T40E offers a TDP of 6.4 watts. The two applications are designed for compact fanless systems, including kiosks and mobile industrial devices, though Axiomtek is apparently planning on incorporating the new APUs in a new Pico-ITX consumer PC, as well. Full PR after the break.

NVIDIA’s GTX 560 desktop GPU fills an exceedingly narrow pricing niche

MSI and ASUS GTX 560 cards

With Tegra 2 hogging the spotlight, sometimes it’s easy to forget that NVIDIA is still primarily in the business of making GPUs for computers. Yet, here it is with the GeForce GTX 560, another graphics chip ready to be inserted into mid-range gaming rigs. This smaller sibling of the GTX 560 Ti is designed to plug right into a small price gap in the company’s lineup — right around the $200 mark. The 336 CUDA cores inside this second-gen Fermi card, predictably, perform slightly better than the GTX 460 and fall just short of the 560 Ti, but it does eke out a victory over similarly priced competition from AMD. The only thing that kept reviewers from wholeheartedly endorsing the various (and often overclocked) flavors of the 560 was the tiny difference in price between it and its relatives — tacking on the letters Ti and its 48 additional stream processors costs as little as $15 after a mail-in rebate. Check out the reviews below for all the benchmarks your little nerd heart can handle. And don’t miss the video of a GTX 560 plowing through Duke Nukem Forever, Alice: Madness Returns, and Dungeon Siege III at the more coverage link.

WebGL flaw leaves GPU exposed to hackers

WebGL attack

Google spent a lot of time yesterday talking up WebGL, but UK security firm Context seems to think users should disable the feature because it poses a serious security threat, and the US Computer Emergency Readiness Team (CERT) is encouraging people to heed that advice. According to Context, a malicious site could pass code directly to a computer’s GPU and trigger a denial of service attack or simply crash the machine. Ne’er-do-wells could also use WebGL and the Canvas element to pull image data from another domain, which could then be used as part of a more elaborate attack. Khronos, the group that organizes the standard, responded by pointing out that there is an extension available to graphics card manufacturers that can detect and protect against DoS attacks, but it did little to satisfy Context — the firm argues that inherent flaws in the design of WebGL make it very difficult to secure.

Now, we’re far from experts on the intricacies of low-level hardware security but, for the moment at least, there seems to be little reason for the average user to panic. There’s even a good chance that you’re not vulnerable at all since WebGL won’t run on many Intel and ATI graphics chips (you can check by clicking here). If you’re inclined to err on the side of caution you can find instructions for disabling WebGL at the more coverage link — but come on, living on the cutting edge wouldn’t be anywhere near as fun if it didn’t involve a bit of danger.

[Thanks, Tony]

NVIDIA losing ground to AMD and Intel in GPU market share

NVIDIA may be kicking all kinds of tail on the mobile front with its ubiquitous Tegra 2 chipset, but back on its home turf of laptop and desktop graphics, things aren’t looking so hot. The latest figures from Jon Peddie Research show that the GPU giant has lost 2.5 percentage points of its market share and now accounts for exactly a fifth of graphics chips sold on x86 devices. That’s a hefty drop from last year’s 28.4 percent slice, and looks to have been driven primarily by sales of cheaper integrated GPUs, such as those found inside Intel’s Clarkdale, Arrandale, and most recently, Sandy Bridge processors. AMD’s introduction of Fusion APUs that combine general and graphics processing into one has also boosted its fortunes, resulting in 13.3 percent growth in sales relative to the previous quarter and a 15.4 percent increase year-on-year. Of course, the real profits are to be made in the discrete graphics card market, where NVIDIA remains highly competitive, but looking at figures like these shows quite clearly why NVIDIA is working on an ARM CPU for the desktop — its long-term survival depends on it.

AMD debuts first embedded GPU with support for OpenCL and six displays

Disappointed by the lack of support for multiple displays and OpenCL in embedded GPUs these days? Then AMD may have just made your day. It’s just debuted its new “desktop level” Radeon E6760 discrete GPU, which packs both OpenCL support and Eyefinity-enhanced support for no less than six independent displays. AMD also notes that the GPU can be paired with its upcoming Llano APU for some additional graphics and parallel computing power and, while it might not wind up in many consumer devices, the company says it’s ideal for everything from casino games to medical imaging. Head on past the break for the complete press release.

NVIDIA brings SLI support to AMD 990FX, 990X and 970 chipsets

It’s not going so far as to expand support as far as AMD has with its CrossFireX multi-GPU technology, but NVIDIA has now at least taken one step in that direction. The company announced today that it’s finally bringing SLI support to AMD platforms — specifically, upcoming motherboards based on AMD’s 990FX, 990X and 970 chipsets. Those will be offered by ASUS, Gigabyte, ASRock, and MSI initially, with additional manufacturers said to be coming on board “shortly.” Hit up the source link below for NVIDIA’s complete statement on the matter — in which it also just so happens to point out that 93 percent of all multi-GPU systems in use today use SLI, according to Steam statistics.

AMD collects half a billion in Q1 profit, Fusion APUs now account for half of its laptop shipments

AMD’s net income for the past quarter was $510 million, generated from $1.61 billion in total revenues. That should make happy reading for a company that’s been raising similar gross revenues previously but finding itself losing cash — though the more intriguing figures are a little deeper in its latest disclosure. CFO and interim CEO Thomas Seifert has noted that AMD “tripled” its Fusion APU shipments relative to last quarter — meaning that at least 3.9 million units have made their way out to OEM partners in Q1 — which now account for “roughly half” of the company’s notebook shipments. In less upbeat news, average selling prices in both the microprocessor and graphics divisions were down sequentially, with AMD having to react to pressure from its traditional foes Intel and NVIDIA. You might surmise that with the mainstream Llano APU out and shipping to computer makers, AMD might have a happier second quarter, but the company’s guidance is for revenues to be flat or slightly down. A final note of pride is reserved for the Radeon HD 6490M and HD 6750M GPUs, which figured prominently in Apple’s latest MacBook Pro refresh and mark a bit of a coup for AMD, who’s now responsible for all of Apple’s discrete graphics across the MacBook Pro and iMac computing lines.

AMD elevates the low-end with trio of sub-$100 cards: Radeon HD 6670, 6570, and 6450

Radeon HD 6670, 6570, and 6450

Graphics card companies don’t live and die by the enthusiast market alone. That may be where the glory is, but it’s the budget cards that really bring in the bacon. For the entry level, AMD just unleashed a trio of sub-$100 cards, the Radeon HD 6670, 6570, and 6450. How do they perform? Well, let’s just say you get what you pay for. Reaction from reviewers has been one of mild indifference. Depending on manufacturer, fan noise does appear to be an issue, possibly precluding the cards from being a viable HTPC choice. Otherwise, even the lowly, $55 6450 is a worthy upgrade over an integrated graphics chip or a two-year-old discrete card, but it can’t match the performance of NVIDIA’s GT 430, which can be had for only a few dollars more. Consensus was that, with prices of the older 5000 series being slashed, purchasers can get more bang for their GPU buck by sticking with last generation cards (like the Radeon HD 5750) if they’re looking for pure gaming prowess. That said, the GDDR5 flavors of the 6670 provide perfectly playable performance on most modern games (it averaged 45 FPS in Call of Duty: Black Ops) for just $99 (the 6570 runs about $79). Just beware those models shipping with GDDR3. Benchmarks galore below.

Radeon HD 6790 sneaks in at under $150, leaves reviewers wanting more for the money

As sure as snow in winter or sun in summer, AMD has yet another refresh to its graphics card portfolio this spring. The Radeon HD 6790 is only a couple of misplaced digits away from the far more illustrious HD 6970, but you should be able to tell the two apart by another, altogether more significant spec: the new mid-tier card retails at $149. Predictably, its performance offers no threat to AMD’s single-GPU flagship, but the 6790’s 840MHz graphics and shader clock speeds plus 1GB of GDDR5 running at an effective 4.2GHz data rate don’t seem like anything to sniff at either. Reviewers agreed that it’s AMD’s slightly delayed answer to NVIDIA’s GTX 460, and with the latter card exiting retail availability to make room for the (oddly enough) less powerful GTX 550 Ti, AMD’s new solution looks set to be the better choice at the shared $149 price point. Alas, being limited to 800 Stream processors and 16 ROPs does expose the HD 6790 to being cannibalized by AMD’s own Radeon HD 6850 (which can be had for sub-$150 if you’re tolerant of rebates) and that turns out to be exactly what happens. A solid card, then, but one that would require an even lower price dip to make economic sense. Benchmarks await below.
