Intel aims for 32 cores by 2010

“Five years ago, Intel envisioned processors running at 20 GHz by the end of this decade. Today we know that the future will look different. CPUs will sacrifice clock speed over core count: Intel’s first “many core” CPU, will run at only two thirds of the clock speed of today’s fastest Xeon CPU – but achieve 15x the performance, thanks to 32 cores,” Wolfgang Gruener reports for TG Daily.

“So far, it has been unclear when those “many-cores” will actually be available. Documents provided by an industry source and seen by TG Daily, however, indicate that at least “dozens of cores” may be still some time away. The first processor of “Keifer” – Intel’s project name for many-core processors – will be surfacing in the 2009/2010 time frame and integrate 32 cores (128 threads total): The first Keifer chip will be manufactured in 32 nm and use eight processing nodes with four cores each. Every node will have direct access to one 3 MB on-die last level cache (LLC) and 512 kB L2 cache. There will be a total of 8 x 3 MB LLC slices that are connected by a ring architecture and represent a total 24 MB of cache,” Gruener reports.

“Intel does not consider AMD’s Opteron and successors as Kevet’s and Keifer’s benchmark. The documents seen by TG Daily aim Keifer at Sun’s “Niagara” architecture, which is currently available in the “Ultra Sparc T1″ processor. The T1 was launched last year with great fanfare as 1.2 GHz 8-core processor with 3 MB L2 cache and capable of handling a total 32 threads at a peak power of just 72 watts,” Gruener reports. “Intel can’t touch the performance of the T1 in its home turf at this time and the specifications of Niagara’s successors are widely based on speculations… Intel knows that a simple increase of threads combined with “multi-core” processors won’t allow the company to keep Sun’s pace. Engineers at the firm believe that a new architecture – which is rumored to be launched in 2008 – and 32 cores are necessary to catch up and ultimately trump Sun in the 2009/2010 time frame: Key to Intel’s advantage may be clock speed, once again: The company estimates that Niagara III won’t be able to run faster than 2.0 GHz – while Keifer will run at least at 2.0 GHz.”
