Because the Gulftown CPU is built on Intel’s 32nm process technology, consumers will be getting a 50% increase in core count and a 50% increase in cache for the same power envelope as current 45nm LGA1366 processors. Based on the Westmere architecture, Gulftown will once again re-integrate the triple-channel memory controller on-die; a change from the first Westmere parts that were released that were dual-core and moved a dual-channel memory controller to a second on-package chip coupled with integrated graphics. (See our Clarkdale CPU coverage here.) And just to clarify – Gulftown will not have integrated graphics on it.
The processor will have 12MB of L3 cache and include HyperThreading and Turbo Boost technology. The die is 240mm^2 and consists of 1.17 billion transistors.
Gulftown will be released both as a consumer part as well as a Nehalem EP processor for servers and workstations. This of course means a return to the world of Intel QuickPath Technology (QPI) as DMI will be limited to the mainstream processors of Lynnfield and Clarkdale. Another interesting change on the Westmere-based processors is that Intel has added support for low-voltage DDR3 memory that will run with little as 1.35 volts compared to the 1.5 volts the controller is at today.
Intel also confirmed that there will be quad-core variants of the Westmere architecture coming soon but no other details on inclusion of graphics, etc, were divulged.
