Intel Launches 8-Core Beast Of A Desktop CPU: Haswell-E Core i7-5960X, HotHardware's Review

Intel Unveils Haswell-E 8-Core Beast Of A Desktop CPU

Intel has officially launched their Core i7-5960X high-end, Haswell-E desktop processor today. Unlike Ivy Bridge-E, which maxed out at 6 cores (12 threads), Haswell-E is an 8-core beast of a machine (16 threads), featuring execution units based on Intel’s latest desktop microarchitecture. The Core i7-5960X has a base clock of 3GHz with Turbo Boost speed to 3.5GHz and will have up to 20MB of shared L3 cache. It also features an integrated quad-channel memory controller with official support for DDR4 memory at speeds up to 2133MHz, although higher speeds are possible through overclocking. Haswell-E based processors also feature up to 40 integrated lanes of PCI Express Gen 3.0 connectivity.

The chip has a 140W TDP, which is slightly higher than the 130W of Ivy Bridge-E based processors. Although it has the same number of pads (2011) as previous-gen Ivy Bridge-E processors, Haswell-E based processors will require new motherboards equipped with LGA 2011 v3 sockets and support for DDR4 memory. Cooler designs from the previous generation are compatible, however.
In general, the Core i7-5960X is faster overall than the previous-gen Ivy Bridge-E based 6-core Core i7-4960X. In single threaded tests, where the Core i7-5960X's additional cache and memory bandwidth aren't fully utilized, the 4960X's higher clocks usually push it ahead. In multi-threaded tests though, the 5960X's two additional cores make it significantly faster. Gaming was also much better on the 5960X.  Read on for our full review, here!
