Intel Core i5 i3 Sept 6

Intel's first truly mainstream, desktop processors based on its Nehalem architecture should be ready in less than two months, a leaked roadmap shows. The first three processors tipped earlier are now reportedly due to arrive on September 6th and, as promised, should be headlined by the quad-core 2.66GHz Core i5 750, 2.8GHz Core i7 860, and 2.93GHz Core i7 870. New, however is word that the i5 part won't support Hyperthreading but that all three will overclock substantially in Turbo Boost mode, reaching as high as 3.2GHz, 3.46GHz and 3.6GHz each when one or more cores can be shut down.

It's expected that these will sell for between $196 and $562 each in batches of 1,000.

Two low-power versions are still due in early 2010. The Core i5 750s and Core i7 860s will have lower default clock speeds of 2.4GHz and 2.53GHz each but will reduce power use from 95W to 82W to improve their usefulness in smaller enclosures. They should still reach the same 3.2GHz and 3.46GHz speeds in Turbo Boost mode. Their more specialized design will reportedly boost the respective prices to $259 and $337.

Dual-core desktop processors under the Clarkdale family also won't ship until early 2010 but should be some of the first Intel chips built on a smaller, more efficient 32 nanometer process. Most will have Hyperthreading and should be topped by 3.2GHz, 3.33GHz and 3.46GHz Core i5 models that ramp up to 3.46GHz, 3.6GHz and 3.73GHz using Turbo Boost. Two lower-clocked but functionally identical Core i3 chips at 2.93GHz and 3.06GHz are also due, as is a lone 2.8GHz Pentium that would have Hyperthreading disabled and a drop to 3MB of Level 2 cache from the 4MB present on the other dual-core systems.

Although their model names haven't been defined, the prices for these CPUs should range from $87 for the Pentium to $284 for the top Core i5.

Early details have also surfaced of Intel's supposed plans for Gulftown and should have the six-core, 32nm processor arrive in early 2010 under the Core i9 label and with a peak energy use of 130W.

    Unless Apple comes out with a mid-tower to fit under the MacPro and above the Mac mini, these will not be used by Apple Inc. Mac Pro needs ECC support, like the xserve and the TDP is way above (2x ) what the iMac or Mac mini supports.

    The 32nm Arrandale at 35W TDP is the target Intel announcement we should be looking forward to. Originally targeted for Q4 2009, things for 32nm have been moving forward a bit better than expected, so maybe September if we are lucky. Times out nicely for inclusion with Snow Leopard.
