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?

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.

Intel goes ULV for laptops to combat the oncoming tablet horde

Intel has been talking up its x86-powered smartphones and battery-sipping Atoms for tablets quite a bit recently, but the company hasn't forgotten its roots in traditional PC form-factors. At an investor event in San Francisco, CEO Paul Otellini announced a significant change to its line of notebook CPUs -- ultra low voltage will be the new norm, not just a niche chip for high-end ultra-portables. The baseline voltage for future CPUs will be in the 10 to 15 watt range, a huge drop from the 35w design of the mainstream Core line and lower than even current-gen ULV chips (which bottom out at 17w). The company also plans to make NVIDIA eat its words by putting the pedal to the metal on die shrinks -- releasing a 22nm Atom next year followed by a 14nm version in 2013. That could mean our fantasy of true all-day battery life in a sleek and sexy laptop will finally come true. Don't crush our dreams Intel!

Microsoft rebuts Intel's claims about Windows 8, calls them 'factually inaccurate'

Bad Intel! Microsoft has issued a strongly worded response to comments this week from Intel SVP Renee James describing the future of Windows 8 on ARM as fragmented and backwards-incompatible. Those statements, says Microsoft, were "factually inaccurate and unfortunately misleading," though we're left without clarification as to what specifically was untrue. James claimed that legacy x86 programs won't be running on the ARM architecture, requiring a re-write for developers and probably a re-purchase for users. She also went on to suggest that each of the four hardware suppliers for Windows 8 systems-on-chip will have a different code stack, incompatible with the rest, which sounds like a far worse allegation to us. Now the issue is to try and figure out which of those two big accusations Microsoft has taken offense to. The Redmond team had nothing more to say on the matter, offering only a reminder that Windows 8 is still at the tech demo stage and there's still a long way to go.

Intel VP confirms ARM versions of Windows 8 will offer no compatibility with legacy apps

We already knew that there would be multiple flavors of the next version of Windows. This is, after all, Microsoft, and if it isn't available in dozens of different SKUs, one for each rung on the ladder from student to corporate executive, then it isn't worth stamping to a disc and throwing in a box. However, thanks to Intel Senior Vice President Renee James, we now know for sure that there will be a decisive split between the various ARM and x86 editions. James confirmed yesterday that x86 versions will work just fine on Intel, AMD, and other compatible chips, running all your legacy applications with aplomb.

However, the ARM versions of the OS (which may number as many as six) won't include any sort of instruction emulation, James saying "Our competitors will not be running legacy applications. Not now. Not ever." That's something that Intel CEO Paul Otellini hinted at back at CES, which means Office running on ARM must have been a re-write -- or at least a re-compile. That's bad news for anyone hoping they'd be able to install Command & Conquer Collector's Edition on the Tegra-powered Windows 8 tablet of their dreams. James additionally indicated there will be four separate Windows 8 ARM SoCs, meaning someone has joined NVIDIA, Qualcomm, and TI since the CES unveil. Intrigue!

VIA QuadCore processor combines low-cost and low-power with 'adaptive overclocking'

Computex is coming up fast and with it we're expecting a slew of new gear. The event will also mark the first public showing of VIA's new x86 quad-core processors aptly named, QuadCore (pictured above center next to a Nano X2). The new procs are manufactured using 40nm processes and combine four Isaiah cores on two dies resulting in a Thermal Design Power of 27.5 watts. That low TDP allows VIA to make the nebulous claim that its first QuadCore L4700 processor is 21 percent more energy efficient than its nearest competitor while offering "awesome" multitasking and multimedia playback performance. Initially available at 1.2+GHz, the 64-bit native processor features adaptive overclocking (think Intel Turbo Boost) for dynamic clock adjustments up to 1.46GHz, a 4MB L2 cache, and 1333MHz front-side bus. Oh, and the QuadCores will be pin-to-pin compatible with VIA Eden, C7, Nano E-Series, and Eden X2 processors when they begin shipping in bulk in Q3. We'll bring you more on these supposed low-cost procs when we see them demoed first hand in Taipei starting May 31st. Until then, click through for the full press release or hit up the more coverage links below for an in-depth preview.
