Some more details of Core i7-2670QM
The core i7-2670QM , is a high end notebook processor with a decent Intel HD 3000 integrated GPU. The 4 cores ensure that you are not stuck up when you need performance.
Some more details of Core i7-2630QM
The core i7-2630QM , is the second generation quad core Sandy Bridge processor, that promises high end CPU performance. Its integrated GPU will also ensure a decent integrated GPU performance. The GPU has a base frequency of 650 MHz and when turbo is in action, its maximum clock frequency can ramp to 1.10 GHz depending upon the demand. One of the reasons for the better performance of the second generation core i7 processors is the improved Turbo Boost 2.0, using which, the processor can stay in the boosted state for a longer duration.
