AMD shaves 800 million transistors from Bulldozer chip, swears nothing's wrong
When a company cuts 40 percent of its transistors from an upcoming processor, one question comes to mind: why? According to ExtremeTech, AMD issued an update stating that its Bulldozer eight core / four module CPU would feature 1.2 billion transistors, as opposed to the previously stated two billion transistors. The reduction occurred despite the fact that the die size remains unchanged at 315 square millimeters -- putting it on par with AMD's lesser Llano chip -- and depriving the chip of valuable horsepower before I/O, an integrated memory controller or HyperTransport are added. When approached for comment, company representatives stated they were simply correcting a mistake regarding the chip's actual specifications. Before you bemoan the fate of the Bulldozer chip, remember that the drummer from Def Leppard has had a terrific musical career with only one arm, so what's the loss of several hundred million transistors to AMD's latest?
AMD ships six-core 'Istanbul' Opteron CPU ahead of schedule
Say it ain't so! Despite AMD's past of announcing more delays than actual shipping products, the outfit has managed to deliver its six-core 'Istanbul' Opteron CPU five months ahead of schedule. Announced today in a company press event, the new chip is shipping today with support for two-, four- and eight-socket servers. If all goes well, they'll be available to order from the likes of Cray, HP, Dell, IBM and Sun later this month, with HE, SE and EE versions of the six-core Opteron planned for the second half of this year. As for performance, users can expect up to 34 percent more performance-per-watt over the previous generation quad-core processors in the same platform, though we wouldn't expect to see these stray too far from traditional server boxes.
AMD's Shanghai proffers 12 cores, HyperTransport 3.0
If your interest in processor speeds doesn't extend much beyond "is it fast?" then these juicy tidbits likely aren't for you. That said, AMD is certainly getting excited about its upcoming Barcelona successor: the 45nm Shanghai. The main points of interest out of the gate are HyperTransport 3.0, which was nixed late in the game on Barcelona, and six cores, which are meant to pit the chip up against Intel's upcoming six-core Dunnington chip. Where things get really exciting is a few months after Shanghai's late 2008 debut, when AMD plans do release a twin-die version, with 12 cores of happiness connected by HyperTransport 3.0. What does all that mean? Beats us, but we hope it's fast.
AMD Phenom FX, X4, X2 Stars to shine in Q3 / Q4
When it's been nearly six months since we've seen an elusive PowerPoint slide pointing to future AMD processors, it's been far too long, but it looks like the forecasting can begin again thanks to information about AMD's star-packed Q3. According to a roadmap slide charting out the future of AMD's "Stars" family of processors, a number of dual- and quad-core processor options will be headed to the desktop market sometime in the third and fourth quarters, and while the firm's "value" Athlon 64 X2 and Sempron chips will also see minor overhauls headed into Q1 of 2008, the focus seems to be on the Phenoms in the crew. The flagship quad-core Phenom FX (dubbed Agena FX) will clock in from 2.2GHz to 2.6GHz, sport 4 x 512KB of L2 cache, 2MB of L3 cache, and sport bus speeds of 3,200MHz or 3,600MHz. The X4 chips ratchet down in speed a bit, and only handle the AM2+ socket while the top-end FX plays nice with the 1207+. The X2 CPUs go the dual-core route, top out at 2.8GHz, but won't be ready for ordering until Q4 of this year.

AMD's revamped roadmap unveils APUs, Hawks, and Griffins
While we've had plenty of time to digest Intel's path forward, we've been critiquing AMD's latest efforts rather than gazing down their intriguing roadmap. Nevertheless, a (presumably yawn-inducing) four-hour presentation yielded a few noteworthy tidbits about where AMD's headed, and how it plans to arrive. The firm insinuated that Intel's gazillion-core approach was simply rehashing the megahertz race, and said it would be focusing it efforts instead on Accelerated Processing Units (APUs). Although the composition is still a bit vague, the devices will supposedly be "multi-core chips that include any mix of processor cores and other dedicated processors," such as discrete units for graphics, physics, audio, video, encoding, etc. While a dash of this has already been divulged when we heard about Fusion, it looks likes AMD's getting pretty serious about it now. Additionally, the desktop roadmap didn't deviate from what we'd previously seen, but the firm plans to unveil a new power-conscience "Hawk" processor to replace the current Turion 64 X2 and Mobile Sempron chips. Moreover, it's working on offering up a hybrid graphics solution, which would see discrete GPUs disabled when unplugged from a power source, letting the integrated graphics set take over and conserve juice. Finally, the company plans to introduce yet another mobile chip (dubbed Griffin) in late 2007 that will reportedly support split power planes and HyperTransport 3.0, hopefully meaning that it'll be based on a quad-core architecture. While we don't exactly recommend sitting through the entire webcast, those who eat, sleep, and drink circuitry can hit the read link for the full (and we do mean full) skinny.[Via TechReport, thanks Keaton]
