One model has Intel's Core i7-2820QM 2.3GHz processor, which HP says can manage a turbo boost speed of 3.4GHz.
There is also one laptop with an i7-2630QM 2GHz processor with a turbo speed of 2.90GHz. HP makes a big thing about how they have a Thermal Design Power of 45 watts. Quite why we are unsure. Normally mainstream Intel laptop processors have a TDP of 25 or 35 watts which means that these could be chucking out a bit of heat unless HP has done something clever with the cooling.
These systems have USB 3.0 support and feature the AMD Mobility Radeon HD 5470 or 5650 graphics card.
