Intel has already revealed its secret plan to dominate the world and simplify its brands, and with this new change, Clarksfield will become Core i7. Clarksfield is nothing more than a slower Lynnfield quad-core based on 45nm Nehalem, but it will be captured in mobile rPGA socket G1.

We told you that mobile Core i7 Extreme, or Lynnfield Extreme how we called it back than will work at 2.0GHz with all four cores and with the help of turbo overclocking, you can hope to see a single core running at 3.2GHz.

Core i7 Clarksfield mobile with 1.73GHz core clock has a 45W TDP, and a single core overclocks all the way to 3.06GHz. it supports DDR3 1333, again fixed speed in comparison with Nehalem generation that officially only certifies DDR3 800 and 1066, and just as Extreme it comes with 8MB of cache.

The competing market is called quad--core performance and when it comes to notebooks, Intel doesn’t really have any competition from AMD or anyone else.
