In terms of overall gaming performance, the AMD Ryzen R7 1800X is massively better than the Intel Xeon E5-2650L v2 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 Ryzen R7 1800X was released over three years more recently than the Xeon E5-2650L v2, and so the Ryzen R7 1800X is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Xeon E5-2650L 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 E5-2650L v2 has 2 more cores than the Ryzen R7 1800X. 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 Ryzen R7 1800X is more than enough for gaming purposes. However, if you intend on running a server with the Xeon E5-2650L v2, it would seem to be a decent choice.

The Xeon E5-2650L v2 has 4 more threads than the Ryzen R7 1800X. Both the Ryzen R7 1800X and the Xeon E5-2650L v2 use hyperthreading. The Ryzen R7 1800X has 2 logical threads per physical core and the Xeon E5-2650L 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 Ryzen R7 1800X and Xeon E5-2650L 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 Ryzen R7 1800X has a 1.9 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 probably a good indicator that the Xeon E5-2650L v2 is superior.

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 Ryzen R7 1800X has a 1536 KB bigger L2 cache than the Xeon E5-2650L v2, but on the other hand, it is the Xeon E5-2650L v2 that has a 9 MB bigger L3 cache than the Ryzen R7 1800X. In this case, the L2 size is probably what counts, so the Ryzen R7 1800X is likely superior in this area.

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 E5-2650L v2 has a 35 Watt lower Maximum TDP than the Ryzen R7 1800X. However, the Ryzen R7 1800X was created with a 8 nm smaller manufacturing technology. Overall, by taking both into account, the Xeon E5-2650L v2 is likely the CPU with the lower heat production and power requirements, by a small amount.

CPU Mini Review

Mini ReviewThe Ryzen R7 1800X is a very high-end CPU based on AMD's 14nm, Zen microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 3.6GHz, which may go up to 4.0GHz using Turbo Boost. It has an unlocked multiplier therefore it can be overclocked using traditional methods. It has 16MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 95W. It is on par with competitor processors. Among its many features, Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFX), Pure Power and Precision Boost are enabled. It doesn't feature an integrated GPU. This CPU is likely to offer excellent computational performance and will not be the bottleneck in any modern gaming PC. Intel Xeon E5-2650L v2 is a Server CPU part of the Xeon E5 Series released by Intel in January 2014.
It's based on the Ivy Bridge architecture and the memory controller supports DDR3-800, DDR3-1066, DDR3-1333 and DDR3-1600.
It has 10 cores and each core has 2 threads, making a total of 20. Intel Xeon E5-2650L v2 Turbo Boost is also available at 2.1GHz
The performance of this server processor is excellent.
