Intel by releasing three new Lynnfield-based Core i5 and i7 parts has significantly shaken up the mid-range of the CPU universe.

The processor world has been pretty uneventful for the past ten months or so since Intel launched the Nehalem-based Core i7 lineup of CPUs. Already intel has worked a lot on Bloomfield-based Core i7 mid range cpu s, which are currently in the market.
Both Bloomfield and Lynnfield parts have around 700 million transistors, based on 45nm architecture, use a monolithic quad-core design, feature 1MB L2 and 8MB of shared L3 cache, includes SSE4.2 support and HyperThreading (not on the Core i5) to name but a few commonalities.
Socket compatibility

The Bloomfield Core i7 parts fit the LGA1366 socket using the X58 chipset, but the Lynnfield CPUs have a lower pin-count and fit into an LGA1156 socket and make use of a P55 chipset.
DMI rather than QPI, Dual-channel rather than triple-channel, Better Turbo Boost are the other few changes in the new Lynnfield CPUs.
The new parts

Here’s some details on the three new parts:

* i5 750 - 2.66GHz - $196
* i7 860 - 2.80GHz - $284
* i7 870 - 2.93GHz - $562
