We just thought you’d like to know that a pair of Lynnfield CPUs arrived in the office today. Lynnfield is the codename for the second generation Nehalem-architecture CPUs that will replace the Core 2 later this year (for more on its actual retail branding, you can read our recent news story).
Lynnfield CPUs differ from current Core i7 CPUs such as the i7-975 in that they have four physical cores, but only the top two models will have logical Hyper-Threaded cores - lower spec Lynnfields will not support Hyper-Threading at all. In addition Lynnfield has a dual-channel DDR3 integrated memory controller instead of supporting triple-channel DDR3. As a result of these changes, Lynnfield CPUs will ship with LGA1156 packaging, so will not work in existing LGA1366 Core i7 or LGA775 Core 2 motherboards.
