A pair of Intel-upper range, Core i7 860 and Core i7 920 close enough for the price and frequency, and the natural question arises: which of these processors is more efficient. In terms of energy consumption and so everything is clear: Core i7 860 with a frequency of 2.8GHz consume 95Vt, while the model Core i7 920 with a frequency of 2.66GHz require 130W. Hence, it is necessary to compare the performance of these processors.

Comparative testing of these processors were held resource. When tested used a motherboard Gigabyte P55-UD6 and video card Radeon HD 4870X2. According to the results of testing Core i7 860 surpassed the Core i7 920 in almost all tests.
