Set for a launch in Q3 2009, Intel's 45nm Core i5 (Lynnfield) processor will come in three flavors: 2.66 GHz, 2.8 GHz, and 2.93 GHz. All three versions will feature four cores (4 threads for the 2.66 GHz version, 8 threads for the other two), 8 MB of L3 cache, a TDP of 95 watts, and will fit snug into the LGA-1156 socket. Additionally, all three versions feature 731 million transistors, an integrated DD3 memory controller, an integrated PCI-Express graphics controller, and support for Turbo Boost. As of today, Intel plans to price the 2.66 GHz version around $196 USD; the 2.96 GHz Core i5 will cost around $562 USD.
However, according to a report over on the Chinese website HKEPC, Intel optimized the Nehalem core as well as its Turbo Mode technology, thus giving the Core i5 a significant 5-step boost while staying within the 95 watt TDP. When set in turbo, Intel's 2.66 GHz version will speed up to 3.2 GHz, whereas the 2.8 GHz version will boost to 3.46 GHz and the 2.93 GHz to 3.6 GHz. The site also said that the two current Core i7 processors--specifically the 2.66 GHz and 2.93 GHz versions originally released in November 2008--will climb two steps as well while remaining within the 130 watt TDP.
HKEPC also confirmed that the Clarksfield quad-core processor for mobile devices will feature Hyper-Threading technology and a TDP of 35 watts; it was speculated that the processor would require a TDP of 45 or 55 watts. Additionally, the processor will come in three flavors--1.6 GHz, 1.73 GHz, and 2.0 GHz--and will also be available in Q3 2009. However, unlike the core i5, the three Clarksfield processors will be a bit more costly, ranging from $364 USD to $1054 USD.
