In terms of overall gaming performance, the Intel Core i9-9900T 8-Core 2.1GHz is massively better than the Intel Core i3-9100F 4-Core 3.6GHz 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.

Both the Core i3-9100F 4-Core 3.6GHz and the Core i9-9900T 8-Core 2.1GHz were released at the same time, so are likely to be quite similar.

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 has 4 more cores than the Core i3-9100F 4-Core. 8 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 i3-9100F 4-Core is more than enough for gaming purposes. However, if you intend on running a server with the Core i9-9900T 8-Core, it would seem to be a decent choice.

The Core i9-9900T 8-Core has 12 more threads than the Core i3-9100F 4-Core. The Core i3-9100F 4-Core has one thread per physical core, whereas the Core i9-9900T 8-Core uses hyperthreading and has 2 logical threads per physical core.

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 i3-9100F 4-Core and the Core i9-9900T 8-Core are from the same family of CPUs, and thus their clock speeds are directly comparable. With this in mind, it is safe to say that with a 1.5 GHz faster base clock rate, the Core i3-9100F 4-Core manages to provide massively better performance than the Core i9-9900T 8-Core. However, the Core i9-9900T 8-Core manages to eke 0.2 GHz higher frequency when being stressed.

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 Core i9-9900T 8-Core has a 1024 KB bigger L2 cache than the Core i3-9100F 4-Core, but on the other hand, it is the Core i3-9100F 4-Core that has a 6128 MB bigger L3 cache than the Core i9-9900T 8-Core. In this case, the L2 size is probably what counts, so the Core i9-9900T 8-Core 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 Core i9-9900T 8-Core has a 30 Watt lower Maximum TDP than the Core i3-9100F 4-Core (though they were created with the same size 14 nm manufacturing technology). What this means is the Core i9-9900T 8-Core 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).

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 Core i3-9100F 4-Core, 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 i3-9100F 4-Core 3.6GHz is a low-end desktop CPU based on a refinement of the 14nm++ Coffee Lake microarchitecture. It is identical to the Core i3-9100 except it does not feature integrated graphics. It offers 4 physical cores (4 logical), initially clocked at 3.6GHz, which may go up to 4.2GHz using 4 cores with Turbo Boost. The i3-9100F has 6MB of L3 Cache. This chip supports up to 64GB DDR-2666 MHz memory. Among its many features, Turbo Boost 2.0, Optane Memory Support, and Virtualization are activated. It does not feature an unlocked multiplier and therefore cannot be overclocked using traditional methods. This Core i3-9100F CPU offers average gaming performance in 2019 and may be a minor bottleneck in a modern gaming PC. It should be able to play most modern games at 60fps on High graphics performance at any supported resolution without being a hindrance to the accompanying GPU, although may struggle with the most demanding AAA titles. Performance may become bottlenecked if playing at 144Hz and 1080p or lower screen resolution.The 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.
