Intel is preparing to launch yet another extreme mobile processor, something to top the current performance king the Core i7 Extreme 920XM. This CPU is an upgrade for Calpella high end performance notebook and it comes in Q3 2010.

The clock speed stops at 2.13GHz but this quad core automatically overclocks all the way to 3.33GHz. This will only happen if it doesn’t get that hot. TDP remains at high 55W and this quad core still supports the quite useless Hyperthreading.

This Clarksfield 45nm CPU comes with 8MB cache and 1333MHz DDR3 support. The only ironic thing about this CPU is that 2.66 GHz Dual-Core Core i7 620M that will overclock to 3.33GHz might easily end up as fast as the much more expensive Core i7 Extreme 940XM that will launch soon.
