Intel Core i7-5960X Extreme CPU Performance Review

Full Disclosure: Intel provided the product sample used in this article.
Benchmark Reviews has now completed performance testing of our Intel Core i7-5960X Haswell-E processor. As this is Intel’s first 8-core consumer processor, we have high expectations for this top-end iteration of the new Haswell-E architecture. Equipped with Intel’s 22nm, “3D” transistors, 20 megabytes of on-chip cache, and a new DDR4 memory controller, the 5960X is unlike anything Intel’s ever done before.
If you haven’t read our Intel Core i7-5960X Extreme Processor Preview article, please do, as it will give you the background you need to get the most from this performance review. However, here’s a quick look at the Haswell-E features and Intel’s family of unlocked desktop-class CPUs to get you started.

Prices are for trays of 1,000 CPUs; individual retail prices will vary.
All of these CPUs use Intel’s latest “Haswell” architecture, with 22nm, 3D transistors. The new LGA2011-V3 CPUs all have DDR4 memory controllers, while the other two get by with DDR3. The one to keep your eye on, though, is the Core i7-4790K. Note that its base frequency is more than 30% higher than that of the 5960X, and its price is about a third of its big brothers’. Will the extra cost of the Haswell-E CPU be justified by its performance?
