In terms of overall gaming performance, the AMD Ryzen 7 3800X 8-Core 3.9GHz is massively better than the Intel Core i9-10900F 10-Core 2.80GHz 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 i9-10900F 10-Core was released less than a year after the Ryzen 7 3800X, 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 Core i9-10900F 10-Core has 2 more cores than the Ryzen 7 3800X. 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 7 3800X is more than enough for gaming purposes. However, if you intend on running a server with the Core i9-10900F 10-Core, it would seem to be a decent choice.

The Core i9-10900F 10-Core has 4 more threads than the Ryzen 7 3800X. Both the Core i9-10900F 10-Core and the Ryzen 7 3800X use hyperthreading. The Core i9-10900F 10-Core has 2 logical threads per physical core and the Ryzen 7 3800X 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 i9-10900F 10-Core and Ryzen 7 3800X 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 7 3800X has a 1.1 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. In this case, however, the difference is probably a good indicator that the Core i9-10900F 10-Core 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 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 i9-10900F 10-Core has a 40 Watt lower Maximum TDP than the Ryzen 7 3800X. However, the Ryzen 7 3800X was created with a 7 nm smaller manufacturing technology. Overall, by taking both into account, the Core i9-10900F 10-Core is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

CPU Mini Review

Mini ReviewThe Core i9-10900F 10-Core 2.80GHz is a CPU based on a refinement of the 14nm++ Comet Lake-S microarchitecture. It offers 10 physical cores (20 logical), initially clocked at 2.80 GHz, which may go up to 5.20 GHz using 10 cores with Turbo Boost. The Core i9-10900F has 20MB of L3 Cache.The Ryzen 7 3800X 8-Core 3.9GHz is a high-end CPU based on AMD's 7nm Zen 2 microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 3.9GHz, which may go up to 4.5GHz using Precision Boost. It has an unlocked multiplier, therefore, it can be overclocked using traditional methods. As an AMD 'X' CPU, the Ryzen 5 3800X can use eXtended Frequency Range (XFR) for automated overclocking. It has 32MB 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 105W. It is power efficient compared to competitor processors. Among its many features are Simultaneous Multithreading, Cool n Quiet, CoolCore Technology, Extended Frequency Range (XFR), Pure Power and Precision Boost are enabled.
