Review: Intel Core i7 3960X Extreme Edition CPU

Benchmarks - memory, plus PiFast

Sandy Bridge is better than Westmere/Gulftown when dealing with instructions-per-clock-cycle throughput. Boosting up to 3.90GHz when dealing with the single-threaded PiFast, the Core i7 3960X is genuinely faster than the Core i7 990X. Understand that most of the gain is from the shift in architecture and not from frequency.
