Intel Core i7-2640M

The Intel Core i7-2640M is a fast dual core processor and made available in the Q3 2011. This processor is the successor of the slower clocked Core i7-2620M. The Intel Core i7-2640M is based on the Sandy Bridge architecture and features Hyperthreading technology that can handle 4 threads at once for additional performance by up 20%. The Intel Core i7-2640M offers a larger L3 cache of 4MB. This processor has a base clock speed of 2.8 GHz but because of the TurboBoost Technology it can increase up to 3.3 GHz when 2 cores are active and 3.5 GHz when only 1 core is active.

This Intel Core i7-2640M also has an improved Turbo 2.0 and an integrated graphics card into the 32nm CPU core. The integrated GPU dubbed Intel HD Graphics 3000 which is fabricated in 32nm technology and shares the fast level 3 cache with the CPU cores. This new integrated GPU is said to be as powerful as the entry level discreet card and therefore can render high definition movies and low resolution games with ease. In the Core i7-2640M the GPU is clocked from 650 to 1300MHz, because of TurboBoost. Additionally, an enhanced dual-channel DDR3 RAM controller is contained within the CPU die which is also used by the CPU and GPU part. It has PassMark rating of 4209.

The chart below shows the processors' performance in terms of PassMark rating. The higher the rating, the better the performance of the processor.
