More light on the reasons behind Intel's promised but shelved Larrabee discrete graphics platform have been revealed. At the Intel Developer Forum earlier this month, the company's director of Graphics Architecture Tom Piazza said Intel faced a performance per watt issue trying to deliver what Larrabee promised.
Intel today quietly said it was canceling its Larrabee dedicated graphics. The company acknowledged that it had missed key steps on the way to completing the many-core graphics technology and that it wouldn't arrive with a competing product on time. Intel's focus from now on would be on the integrated graphics such as those it uses in newer Core i3, i5 and i7 chips.
The long rumored and denied next-generation Nintendo Wii HD may get a new processor from Intel, in the form of its Larrabee graphics platform, according to reports from Japan. The multi-core chip is suitable to both general and graphics processing, which is ideal for use in gaming consoles. Just yesterday it has also been rumored to be a candidate for use in Sony's PS3 replacement.
Sony may drop the Cell processor entirely in the PlayStation 4 in favor of a multi-core design, a report from Impress says. Having first considered a modified, upgraded version of the Cell processor that powers the PS3, the electronics giant is now believed considering a new processor design that would use a more direct design with multiple true processor cores. The switch if implemented would be a concession to developers, who have regularly complained that writing PS3 games is too difficult.
Intel is delaying the launch of its much-anticipated Larrabee standalone graphics chip. While only admitting that its Larrabee discrete graphics chip project was behind schedule and that it would initially only appear as a software development platform "next year," one analyst suggests that the company may be missing its performance targets for Intel's first major-market graphics chip.
(Updated with official stance) On a recent trip to China, Intel's CEO Paul Otellini has been talking about the chipmaker's upcoming high-end Larrabee GPU with China-based graphics card makers, DigiTimes reported on Tuesday, citing sources at the card makers. They claim Intel is planning on offering preferential pricing for the GPU both on its own, as well as bundled with other Intel products. The Larrabee is expected to compete with NVIDIA's GeForce and AMD's Radeon products and is due for a 2010 launch.
A prematurely released copy of Intel's plans for a Wednesday keynote has surfaced a day in advance and has provided details of the company's plans for the near future. The release obtained by ZDNet has Intel executive VP Sean Maloney revealing that the company has started shipping its many-cored Larrabee graphics chip to developers ahead of a full release and demonstrating what it can do in real-time. The demo should show a custom build of the online shooter Enemy Territory: Quake Wars running with raytraced lighting, a feat which is technically difficult for any graphics hardware as it calculates the path of each ray of light rather than making "shortcut" calculations.
Intel at the opening of Saarland University's Visual Computing Institute on Wednesday gave clues as to its plans for its many-core Larrabee graphics processor. In a presentation to guests, the semiconductor firm showed that the design uses 32 processor cores and mates each of these with its own vector math unit, allowing each core to process very specialized tasks very efficiently. They also have a pool of cache memory and a memory interface on their edges.
Intel today provided some initial details of its Larrabee graphics architecture and thus its first attempt to directly challenge stand-alone graphics chipsets from AMD and NVIDIA. The semiconductor firm believes it has solved the problems of extending graphics features by using multiple, complete x86 processor cores that are more consciously designed to recognize multiple program threads and support Hyperthreading to run more than one thread at the same time; it also adds a dedicated vector processor per core to aid in graphics-related tasks.
Speaking to the press in a conference call, Intel has revealed more details on some of its upcoming processor technologies. Among these is "Larrabee," an upcoming graphics chipset; while it should be integrated into motherboards, as Intel has done with most such efforts, the company says it expects to produce dedicated cards, raising the specter of competition with NVIDIA and AMD/ATI. Larrabee processors should scale to the multi-teraflop level, and will use a global cache shared by all cores. Larrabee products should begin shipping in 2009.
