Full Disclosure: Intel provided the product sample used in this article.
Intel has upped the ante for LGA2011 systems with the new LGA2011-V3 specification, comprising the new X99 chipset and Haswell-E CPUs. The top-end Core i7-5960X is Intel’s first consumer 8-core CPU and boasts an amazing 20 megabytes of on-chip cache and a new quad-channel DDR4 memory controller. As with the original “Sandy Bridge Extreme” Core i7-3960X CPU, the new Haswell-E systems will be very expensive. Benchmark Reviews does the work so you can see if they make sense for you.
This article will discuss the specifications and architecture of Haswell-E and the new X99 LGA2011-V3 platform, with performance tests to follow shortly.

The top three CPU are comprise the new Haswell-E family. Note how the base and turbo clocks go down with the number of cores; in fact, the 5960X has lower clocks than the original 3960X, which had base and turbo clocks of 3.3 and 3.9gHz, respectively. The quad-core 4790K has clock speeds more than 30% higher, which, given that its core architecture is the same, should mean better performance in 4-thread or lower workloads.
Also, the 140 watt TDP means that you’re going to need a good CPU cooler; Intel recommends water cooler for any over clocking. At least LGA2011-V3 cooler mounting holes haven’t changed!
If you’re planning to run multiple GPUs, notice that the Core i7-5820K has only 28 PCI-E lanes.
