Intel Core i7-5960X Extreme Haswell-E Processor Now Available – See Features, Specs, Benchmarks, Price and Availability

Intel’s latest and highest-end processor for high end desktop system – the Intel Core i7-5960X Extreme Edition Haswell-E CPU is now available, together with the Core i7-5930K and i7-5820K. The Intel Core i7-5960X Extreme is the company’s first flagship processor built for X99 system, featuring 8 native cores and 16 threads, with a maximum Turbo speed of 3.5GHz. It’s not basically designed for gaming, but it is definitely designed for serious and demanding number crunching operations, calculations and heavy multi-tasking. The Core i7-5960X can definitely handle any load you threw at it, but this extreme processor is definitely not for the regular consumers. Check out more of its features, specifications, some benchmarks, as well as price and where to buy below.

Intel Core i7-5960X Extreme Features

The Intel Core i7-5960X Extreme Edition is based on the 22nm manufacturing process that features a total of 8 native physical cores, with 16 threads, running at a base clock speed of 3GHz, up to 3.5GHz via Turbo. It is designed for the latest Intel X99 platform supporting the latest DDR4 memory modules, and features a slightly different socket LGA 2011-v3. The Core i7-5960X is not backwards compatible with the previous generation (Ivy Bridge-E). It has a maximum thermal design power of 140W, 10w higher compared to the previous generation, and it is recommended that you should use a high end CPU air cooler, or a water cooling solution to cool this beast.

It supports a maximum number of 40 PCI Express Lanes making it great for users who plan to install 3 or 4 graphics card into their system. It also comes with 20MB L3 cache, 32KB for each core and 256KB for L2 cache. It’s also able to drive dual or quad channel DDR4 memory modules with speeds up to 2133MHz. Of course you can install DDR4 memory with speeds of 3000MHz and overclock it further. The same principle applies with its clock speed where you can still push it further beyond 3.5GHz.

Intel Core i7-5960X Extreme Benchmarks

Below are links to specific pages of tech sites where you can view some Intel Core i7-5960X CPU benchmarks.

Based on those benchmark results, Intel’s latest flagship processor did shine and outperform the rest of the processors currently in the market most of the time. However, that’s not the case when it comes to gaming. The Core i7-5960X didn’t perform that great when it comes to PC games, although the results where high, but not as good compared to other processors and the price simply isn’t justifiable for gaming purposes alone. PC gamers might want to stick with the Devil’s Canyon or Core i7-5820K and Core i7-5930K instead.
