In terms of overall gaming performance, the Intel Xeon E7-8895 v2 is massively better than the Intel Core i9-7920X 12-Core 2.9GHz 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 Core i9-7920X 12-Core was released over three years more recently than the Xeon E7-8895 v2, and so the Core i9-7920X 12-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Xeon E7-8895 v2 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 E7-8895 v2 has 3 more cores than the Core i9-7920X 12-Core. 15 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 i9-7920X 12-Core is more than enough for gaming purposes. However, if you intend on running a server with the Xeon E7-8895 v2, it would seem to be a decent choice.

The Xeon E7-8895 v2 has 6 more threads than the Core i9-7920X 12-Core. Both the Core i9-7920X 12-Core and the Xeon E7-8895 v2 use hyperthreading. The Core i9-7920X 12-Core has 2 logical threads per physical core and the Xeon E7-8895 v2 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 Core i9-7920X 12-Core and Xeon E7-8895 v2 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 i9-7920X 12-Core has a 0.1 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. As such, we need to look elsewhere for more reliable comparisons.

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 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 Core i9-7920X 12-Core has a 15 Watt lower Maximum TDP than the Xeon E7-8895 v2, and was created with a 8 nm smaller manufacturing technology. What this means is the Core i9-7920X 12-Core will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

CPU Mini Review

Mini ReviewCore i9-7920X 12-Core 2.9GHz is a high-end CPU based on the 14nm Skylake-X micro architecture. It offers 12 physical cores (24 logical), initially clocked at 2.9GHz, which may go up to 4.4GHz with boost, and 16.5MB of L3 Cache. Among its many features, Turbo Boost 3.0 and Virtualization are activated and the processor has its multiplier unlocked. With a 140W TDP, the Core i9-7920X 12-core processor is very power hungry. The Intel Core i9-7920X is part of the first ever generation of Core i9 processors. These CPUs are designed to offer the fastest gaming performance of all Intel CPUs.The Xeon is a brand of x86 microprocessors designed and manufactured by Intel Corporation, targeted at the non-consumer workstation, server, and embedded system markets. Primary advantages of the Xeon CPUs, when compared to the majority of Intel's desktop-grade consumer CPUs, are their multi-socket capabilities, higher core counts, and support for ECC memory.
