i7-8xx line of mobile Core i7 microprocessors provides superior performance than i7-7xx series by enhancing a few processor features. The 820QM and upcoming 840QM processors run one step, or 133 MHz, faster than 7xx models released at the same time. Level 3 cache on 8xx line of processors is increased to 8 MB, and Turbo Boost frequency is usually by one or two steps higher than on the i7-7xx mobile CPUs. Better performance comes at premium price, though. While this CPU in some tasks can be faster than the i7-720QM by up to 15%, it currently (June 2010) has 50% higher price the 720QM.
