AMD exec behind Wii and Xbox 360 graphics jumps the fence to NVIDIA
AMD has been suffering a conspicuous brain drain, with executives like ATI veteran Rick Bergman and CTO Eric Demers crossing over to tangentially or directly competitive companies like NVIDIA and Qualcomm. Chalk up another one for the list -- strategic development VP Bob Feldstein has bounded towards NVIDIA's (literally) greener pastures. The blow cuts deeper than usual through Feldstein's responsibility for graphics in most of the consoles from the past few years: he headed up work behind the Xenos chip in earlier Xbox 360s and the Hollywood core in the Wii, and he likely had some say in the Wii U's video hardware as well. While the staff shuffle won't directly affect AMD's Fusion processors or Radeon cards, it's hard to see much of a positive for AMD's future in video gaming, even in the light of rumors that the next PlayStation and Xbox might use some of Feldstein's work.
New Xbox 360 gets a proper teardown analysis: power and noise reductions confirmed
Anyone can take a hammer and rib-spreader to a new piece of hardware. But it takes someone like Anand Shimpi, the man behind Anandtech who has personally suffered through four out-of-warranty Xbox 360 failures, to bring sage analysis to a teardown of the new Xbox 360. His reluctant sixth Xbox 360 is the new slimster (codename Valhalla) which, for the first time, combines the CPU, GPU, and eDRAM onto a single chip -- previous Xbox 360 motherboards featured two discrete packages that split the CPU from the ATI designed Xenos GPU and eDRAM. The design allows for a single heatsink to be cooled by a single, larger fan making the new Xbox "noticeably quieter," measured at 45dB when idle or 51dB with the 1.5Gbps SATA Hitachi HTS545025B9SA00 with 8MB buffer spinning at 5400RPM -- that's down from 50dB and 54dB, respectively, as measured on late 2008 through 2010 Jasper-class 360s. Regarding power consumption, Anand measured a 50% reduction from the original 2005 Xbox 360 (25% less than Jasper-class rigs at idle, or 20% to 17% less under load) and pulled just 0.6W when "totally off" compared to the 2W of vampire power pulled by older 360s. Anand speculates that Microsoft might finally be using cheaper 40nm components. However, we shouldn't expect to see a price cut anytime soon as it will take Microsoft awhile to ramp up the material and manufacturing cost savings. Regardless, with Kinect and several new game titles on the horizon, Anand concludes that there's still plenty of life left in the old Xbox 360 platform for those looking to make the jump.
Xbox 360 getting 65nm GPU this fall?
While it's hardly a secret that the Xbox 360 will be getting a 65nm CPU upgrade sooner or later, China's Commercial Times (not always the most reliable source) is now reporting that the console's Xenos GPU will also be switching over to the cooler, lower-power chips, supposedly sometime this fall. According to the paper, an "engineering version" of the new and improved 65nm Xenos GPU has already been sent out, with production set to get underway in May, which would certainly seem to make a fall launch a possibility. Unfortunately, there's still no word on a possible disc drive upgrade to go along with these other revisions, which we all know is the real culprit for most of the console's noise problems.[Via Joystiq]
The amazing 360 GPU shrinks to 65nm this Fall
According to sources close to equipment manufacturers, later this year we'll be ushering in a new and improved Xbox 360 GPU. A Chinese report in the Commercial Times is stating that the new 65nm 360 GPU will be sent to production in May and make its way into Xbox 360 consoles later this Fall. And we all know the benefits of 65nm technology. So, anyone in the market for a new 360 or jumping in for the first time and going to hold out until the new 65nm technology makes it into the console? Or could you care less unless it would involve an Xbox 360 price cut?[Via Joystiq]
Xbox 360 Xenos GPU shrinks to 65nm this fall
We know the 65nm version of Xenon, the Xbox 360's triple-core CPU, had been delayed from Q1 2007 to "mid-2007," just missing being used in the Xbox 360 Elite, making irony the system's most prominent feature. But the CPU isn't the only thing getting shrunk: DigiTimes reports that the Xbox 360 will be equipped with a 65nm Xenos GPU this fall as well, with production of the new graphics chips scheduled for May. For those of you on the fence about the Elite, a newer, cooler, and cheaper (to manufacture) Xbox 360 should be here in the fall. The question: wait or jump in?[Thanks, Fandel]
Meet Ana, the Xbox 360 hardware scaler
How did Microsoft dodge the scaling issue that has plagued Sony since its launch? Maybe it was the timing -- an HD console in a Standard Def world -- or perhaps it was Ana, the affectionate title for Xbox 360's hardware scaler. Whereas the PlayStation 3 downscales to meet resolution, Ana upscales Xbox 360 titles to 1080p to impressive results, according to Ars Technica's Ben Kuchera. Speaking with Microsoft's Scott Henson, Kuchera learns that Ana was designed at the same time as Xenos, the console's GPU. Though the addition of a PS3 hardware scaler is possible in the future, Xbox Group Product Marketing Manager Aaron Greenberg opines that it would be difficult for Sony to fix the issue with software, leaving first-generation PS3 owners in the cold.However, the truth is, as Kuchera notes, differences between the two console's graphics are minimal to nonexistent. "By [the time PS3 has second-generation titles] we'll have Halo 3," Henson said. "We'll be on the third–generation games. We hope to always be a little bit ahead." When will Sony pull ahead of the Xbox 360, graphically, and to what extent is Ana Microsoft's secret weapon in keeping up?See Also: The second Xbox 360 (with HDMI): introducing "Zephyr" [Thanks, Theo1130; image inspiration]
