In terms of overall gaming performance, the Intel Core i7-5960X 8-Core 3.0GHz is massively better than the Intel Xeon E5-2660 v3 when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

The Xeon E5-2660 v3 was released less than a year after the Core i7-5960X 8-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The Xeon E5-2660 v3 has 2 more cores than the Core i7-5960X 8-Core. 10 cores is probably excessive if you mean to just run the latest games, as games are not yet able to harness this many cores. The cores in the Core i7-5960X 8-Core is more than enough for gaming purposes. However, if you intend on running a server with the Xeon E5-2660 v3, it would seem to be a decent choice.

The Xeon E5-2660 v3 has 4 more threads than the Core i7-5960X 8-Core. Both the Xeon E5-2660 v3 and the Core i7-5960X 8-Core use hyperthreading. The Xeon E5-2660 v3 has 2 logical threads per physical core and the Core i7-5960X 8-Core has 2.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The Xeon E5-2660 v3 and Core i7-5960X 8-Core are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the Core i7-5960X 8-Core has a 0.4 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. In this case, however, the difference is enough that it possibly indicates the superiority of the Xeon E5-2660 v3.

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The Xeon E5-2660 v3 has a 512 KB bigger L2 cache than the Core i7-5960X 8-Core, which means that it, at worst, wins out in this area, and at best, will provide superior gaming performance and will work much better with high-end graphics cards.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.

The Xeon E5-2660 v3 has a 35 Watt lower Maximum TDP than the Core i7-5960X 8-Core (though they were created with the same size 22 nm manufacturing technology). What this means is the Xeon E5-2660 v3 will consume significantly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill significantly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewXeon E5-2660 v3 is an upcoming server processor based on the 22nm, Haxwell microarchitecture. Core i7-5960X 8-Core 3.0GHz is an extreme processor based on the 22nm, Haswell architecture.

It offers 8 Physical Cores (16 Logical), initially clocked at 3.0GHz, which may go up to 3.5GHz and 20MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated and the processor has multiplier unlocked, meaning it can be overclocked easily.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 140W.

It proves to be over 10% faster than Core i7-4960K. Its performance is exceptionally good and enough for even the most demanding applications.
