In early 2010, Intel's die-shrink to 32nm leads to the first available desktop processors in the Westmere generation; the Clarkdale Core i5 6xx. In the second quarter of 2010, we are to expect the high-end Gulftown chip, Which is rumored to be called Core i9 a 6-core processor.
The Gulftown would be launched exclusively as an Extreme Edition processor for Socket 1366 only, like the current Bloomfield Core i7 975 XE. With 6 cores and HyperThreading, the chip is capable of processing 12 threads simultaneously. The Gulftown is to sport 6x256 kB of L2 cache and 12 MB of L3 memory. It's rumored that the TDP (Thermal Design Power, which represents the maximum amount of power the cooling system in a computer is required to dissipate.) will be specified at 130 watts. But it is still unknown what the Gulftown's final clock frequencies will be, but the multiplier won't be locked and Turbo Boost is supported as well.
The processor's integrated memory controller is compatible with DDR3-memory at a 1066 MHz clock frequency. The Gulftown uses Intel's QPI connection to communicate with the X58 chipset.
The six-core (hexacore) processor codenamed Gulftown, with support for only Socket LGA1366 is based on 32nm technology, operating / starting at 2.4GHz (18*133MHz), with 12MB of L3 cache; and it is compatible with the X58 chipset.
The 32nm Gulftown 6-core (or hexa-core), chip will launch in Q1 2010 as the first true chip in the Westmere family, the successor to Nehalem. Intel Core i9 will appeal to and is intended for a highly enthusiast market niche, as it is based solely on socket LGA 1366 and retains compatibility with the X58 chipset which isn’t going anywhere in the foreseeable future.
From a clearly analytical perspective, Core i9 Gulftown can be viewed as Core i7 + 2, with 6 physical cores, a total thread count of 12 and a 50 percent L3 cache increase over Core i7 Bloomfield. It should also be know that Gulftown will not include an IGP core alongside the 32nm CPU (no chip integrated graphics controller), so nothing changes on the graphics front.
Intel's X58 chipset and socket LGA1366 only (like the Bloomfield) will be required - this chip will not be compatible with any i5 (Clarksdale) motherboards socket LGA1156.
And here is how it breaks down and compares with the rest of the new modern processors:
