Intel Core i7-820QM

Intel 820QM

The Intel Core i7 820QM is a high end quad core CPU in 2009. It features 4 cores (quad core CPU) and Hyperthreading. Therefore, 8 threads can be worked on simultaneously.

Because of the Turbo Mode, the CPU is clocked with up to 3.06 GHz and therefore can perform very well in single core applications like older games.

The Core i7 line has an integrated memory controller for DDR3 bars (1066 or 1333). Therefore, the memory performance is very good (compared to older CPUs with external memory controllers). Still, this also leads to the higher TDP of the whole chip.

The Core micro-architecture is still very similar to the one used in the Core 2 CPUs, therefore the performance per MHz (neglecting the integrated memory controller, hyperthreading and Turbo Boost) is similar.

The power consumption of up to 45 Watt (TDP) is quite high for a laptop CPU and because of the Turbo Mode, the power consumption should reach these high values. Therefore, the CPU is only suited for large laptops.
