In terms of overall gaming performance, the AMD Threadripper 2950X 16-Core 3.5GHz is massively better than the AMD Ryzen 7 3800X 8-Core 3.9GHz 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 Ryzen 7 3800X was released less than a year after the Threadripper 2950X 16-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 Threadripper 2950X 16-Core has 8 more cores than the Ryzen 7 3800X. 16 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 Threadripper 2950X 16-Core, it would seem to be a decent choice.

The Threadripper 2950X 16-Core has 16 more threads than the Ryzen 7 3800X. Both the Ryzen 7 3800X and the Threadripper 2950X 16-Core use hyperthreading. The Ryzen 7 3800X has 2 logical threads per physical core and the Threadripper 2950X 16-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 Ryzen 7 3800X and Threadripper 2950X 16-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 Ryzen 7 3800X 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 Threadripper 2950X 16-Core.

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 Threadripper 2950X 16-Core has a 4096 KB bigger L2 cache than the Ryzen 7 3800X, and the two CPUs have the same L3 cache size, so the Threadripper 2950X 16-Core wins out in this area with its larger L2 cache.

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 Ryzen 7 3800X has a 75 Watt lower Maximum TDP than the Threadripper 2950X 16-Core, and was created with a 5 nm smaller manufacturing technology. What this means is the Ryzen 7 3800X 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 ReviewThe 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.The AMD Threadripper 2950X 16-Core 3.5GHz is a very high-end CPU based on AMD's 12nm Zen+ microarchitecture. It offers 16 physical cores (32 logical), initially clocked at 3.5Hz, which may go up to 4.4GHz using Turbo Boost. It has an unlocked multiplier, therefore it can be overclocked using traditional methods. 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 1TB. It has a maximum Thermal Power Design of 180W. It is on par with competitor processors. Among its many features, Enmotus FuzeDrive for AMD Ryzen, AMD SenseMI Technology, AMD Ryzen VR-Ready Premium, Virtualization, AES, AVX2, FMA4, XFR (Extended Frequency Range) It doesn't feature an integrated GPU. The Threadripper 2950X 16-Core 3.5GHz's high core count and high clock speed make it a great but expensive option for gamers. It will run AAA games very well. While a high clock speed is a priority for gaming, 16 cores is excessive for most gaming applications in 2018.
