Intel on Nehalem, etc.
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.
Regarding the previously-hinted Nehalem CPU, Intel says chips will ship in the fourth quarter of 2008, and will support anywhere between two and eight cores, with multithreading simulating between four to 16. Bandwidth should be four times that of the best Xeon, with 8MB of L3 cache, and QuickPath connections operating at 25.6GB per second. A memory controller will be integrated by default, and instruction support will include SSE4.2.
The company has lastly confirmed details of the Dunnington design, noting that CPUs will have six cores, a 16MB L3 cache, and an expected release in the second half of 2008. The processor should also be especially adept at virtualization, thanks to a single pool that handles live 65 and 45nm virtual machines. [via The Inquirer]
