Hasta La Gadget!

Sounds like Notbooks are making a dent: AMD says it’s shipped five million Fusion processors since the architecture’s debut, according to a report at CNET. In January, the company said the hybrid CPU / GPU chips had momentum, and as of last month it was quoting 3.9 million APUs out in the wild, but this week AMD says that demand has overtaken supply and it’s completely sold out of the Atom alternative. Sounds like Intel’s more than justified in seeking out hybrid solutions of its own, no matter where it might have to look to get a leg up in the integrated graphics market. Here’s hoping AMD’s other Fusion chips show just as much pep per penny (and milliampere-hour) as the original processor.

Piling on cores is one way to boost performance, but it’s not necessarily the most efficient way — researchers at North Carolina State University have developed a new prefetching technique for processors that could boost performance by up to 40-percent. As you may know, any data not stored in a CPU’s cache must be pulled from RAM, but as more cores are added they can create a bottleneck by competing for memory access. To counter this designers use prefetching to predict what information will be needed and grab it ahead of time, but guessing wrong can hurt performance. Researchers tackled this problem from two fronts: first, by creating a better algorithm for divvying up bandwidth, and second, by selectively turning off prefetching when it might slow the CPU. Full PR and an abstract of the study being published June 9th are after the break.

Don’t mistake the relative quietness from AMD on the APU front for inactivity. Ever since announcing the first shipment of its Llano Accelerated Processing Unit in April, the company’s been working behind the scenes to ramp up availability to OEMs, and somewhere along the supply chain a gracious soul has been found who’s leaked the bulk pricing for those chips. The new quad-core A Series processors start off at $110 for an A6-3450 and max out at $170 for an A8-3550P, but there’s also mention of octa-core FX processors, which will weigh in at $320 a piece and reputedly compete with Intel’s 3.4GHz Core i7-2600K. The latter are built around AMD’s Bulldozer modules (wherein one module counts for two cores) and look to be the manifestation of the company’s Zambezi CPUs, which could come without an integrated graphics processor as is available on the Llano and the rest of AMD’s Fusion line.

Just to whet appetites further, we’ve also come across an HP dv6 on an obscure German retail site, offering a 1.6GHz A6-3410MX APU, 6GB of RAM, and a most reasonable €590 price. There’s obviously no promised delivery date, but this should be the first of many such appearances in the coming days as we build up towards Computex 2011. Something tells us AMD won’t be holding back when the Taipei electronics show gets started.

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 TDP 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!

We knew Intel and Apple had a close working relationship when it came to developing Thunderbolt, but now an exec from Santa Clara has taken the declarations of mutual admiration to the next level. Tom Kilroy, Senior Vice President and General Manager of Intel’s Sales and Marketing Group, told a Reuters tech summit that Apple isn’t merely important to his company’s plans, it actually “helps shape [Intel’s] roadmap.” Those are strong words coming from the world’s biggest maker of processor chips, one that you wouldn’t expect to be beholden to any hardware or software partner. Additionally, it marks the second time this week that Intel has indirectly slighted Microsoft, the first one being a damning analysis of Windows 8 on ARM by fellow Intel SVP Renee James. It’d be easy to conclude that we’re seeing cracks developing in the old Wintel bond, but we reckon it’s more likely that Chipzilla is simply finding the wrong words to express otherwise benign thoughts. Hit the source link for more from Mr. Kilroy.
