On this page, we overclock the Core i7 950 to 3.4ghz, matching the speed of the 2600k. This is a good way to measure the architectural improvements between the new generation and the last generation.
A similar set of scaling improvements which we noted earlier during the 2500k element of the review. Again, we see a very slight reduction in performance from the SHA256 Cryptography test when both processors are at the same clock speeds.
