Notes
We're comparing Intel's best-ever consumer CPU to the Core i7-3960X - the 6C/12T Sandy Bridge-E chip with similar underpinnings. It also makes sense to see how the nascent Core i7-4770K Haswell compares and, finally, the FX-8350 from AMD. We have been careful to ensure the chips run system memory at their maximum supported speeds.
All testing has been done from the ground-up and provides a solid indication into top-tier CPU performance in mid-2013. For those that want a wider comparison, please head on over to the 4770K chip review; we compare it to other IGP-based processors.
The benchmark suite has been tweaked to take account of the extra cores and threads on offer, and we place a greater emphasis on multi-core ability than with standard CPU reviews.
