Debuting today are three mobile Core i7s: two mainstream parts and an Extreme-branded gamer-centric part. Like Lynnfield, the new mobile processors support dual-channel DDR3-1333 memory, have 16 lanes of PCI Express 2.0 connectivity right on the CPU die, and bring Turbo Boost functionality to the table. All three mobile Core i7s are quad core parts and have Hyper-Threading enabled for a total of eight simultaneous threads. Here's a rundown of the new chips and their respective specs:
|Processor Model||Cores / Threads||Clock Speed||L3 Cache||TDP||Price|
|Core i7-920XM||4/8||2.00 GHz to 3.20 GHz||8 MB||55 W||$1,054|
|Core i7-820QM||4/8||1.73 GHz to 3.06 GHz||8 MB||45 W||$546|
|Core i7-720QM||4/8||1.60 GHz to 3.06 GHz||6 MB||45 W||$364|
