Intel announces Core i7 Mobile, Clarksfield

After launching its second Nehalem-based processor architecture Lynnfield and LGA1156 platform Intel has taken the next step. It has launched the first mobile processor based on the popular architecture. Intel Core i7 Mobile, code-named Clarksfield, is more or less identical to Lynnfield. The CPU core is the same, but with lower clock frequencies and smaller formfactor we get Intel's mobile Core i7 family, which is matched by a mobile version of the Intel P55 chipset.

Intel has announced three models using the 45nm Clarksfield core, the dynamic trio looks as follows.

It's easy to spot the similarities with the desktop CPU Lynnfield with the four cores, HyperThreading and 8MB L3 cache, though the entry model has to settle for 6MB L3 cache.

The most astonishing feat is the Turbo Boost mode, where the top model Core i7-920XM can increase the clock frequency by more than 55% (!) through Turbo Boost, which almost makes Lynnfield seem boring.

The new mobile processors still consume rather a lot of power when they are pushed, but are very efficient at low loads. Those who are interest in a Nehalem-based processor for their new notebook can check the tests below.
