In terms of overall gaming performance, the AMD Ryzen 7 3700X 8-Core 3.6GHz is massively better than the Intel Core i9-9900T 8-Core 2.1GHz 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 3700X was released less than a year after the Core i9-9900T 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 Core i9-9900T 8-Core and the Ryzen 7 3700X both have 8 cores. Games are not yet able to harness this many cores, so it is probably excessive if you mean to just run the latest games; however, if you intend on running a server with this CPU, it would seem to be a decent choice.

Both the Intel Core i9-9900T 8-Core 2.1GHz and the AMD Ryzen 7 3700X 8-Core 3.6GHz have the same number of threads. Both the Core i9-9900T 8-Core and the Ryzen 7 3700X use hyperthreading. The Core i9-9900T 8-Core has 2 logical threads per physical core and the Ryzen 7 3700X 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 i9-9900T 8-Core and Ryzen 7 3700X 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 3700X has a 1.5 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 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 7 3700X has a 2048 KB bigger L2 cache than the Core i9-9900T 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 Core i9-9900T 8-Core has a 30 Watt lower Maximum TDP than the Ryzen 7 3700X. However, the Ryzen 7 3700X was created with a 7 nm smaller manufacturing technology. Overall, by taking both into account, the Core i9-9900T 8-Core is likely the CPU with the lower heat production and power requirements, by a small amount.

The Core i9-9900T 8-Core has an on-board GPU, which means that it will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card. The Ryzen 7 3700X, however, does not, and you will probably have to look for a dedicated card if you wish to use it at all.

On-board GPUs tend to be fairly awful in comparison to dedicated cards from the likes of AMD or Nvidia, but as they are built into the CPU, they also tend to be cheaper and require far less power to run (this makes them a good choice for laptops). We would recommend a dedicated card for running the latest games, but integrated GPUs are improving all the time and casual gamers may find less recent games perform perfectly acceptably.

CPU Mini Review

Mini ReviewThe Core i9-9900T 8-Core 2.1GHz is a high-end CPU based on a refinement of the 14nm++ Coffee Lake microarchitecture. As a 'T' CPU this is a low-power desktop variant. It offers 8 physical cores (16 logical), initially clocked at 2.1GHz, which may go up to 4.4GHz using 8 cores with Turbo Boost. The i9-9900T has 16MB of L3 Cache. Among its many features, HyperThreading, Turbo Boost 2.0, and Virtualization are activated, although this processor does not have its multiplier unlocked. This Core i9-9900T CPU offers fast gaming performance and will not be the bottleneck in any modern gaming PC. It will be able to play all modern games comfortably on ultra graphics performance at any supported resolution without being a hindrance to the accompanying GPU.The Ryzen 7 3700X 8-Core 3.6GHz is a high-end CPU based on AMD's 7nm Zen 2 microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 3.6GHz, which may go up to 4.4GHz using Precision Boost. It has an unlocked multiplier, therefore, it can be overclocked using traditional methods. As an AMD 'X' CPU, the Ryzen 5 3700X 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.
