In terms of overall gaming performance, the AMD FX-9590 is massively better than the Intel Core i3-8300T 4-Core 3.2GHz 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 i3-8300T 4-Core was released over three years more recently than the FX-9590, and so the Core i3-8300T 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the FX-9590 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 FX-9590 has 4 more cores than the Core i3-8300T 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 i3-8300T 4-Core is more than enough for gaming purposes. However, if you intend on running a server with the FX-9590, it would seem to be a decent choice.

The FX-9590 has 4 more threads than the Core i3-8300T 4-Core. Both CPUs have one thread 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 i3-8300T 4-Core and FX-9590 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 FX-9590 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 FX-9590 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 i3-8300T 4-Core has a 185 Watt lower Maximum TDP than the FX-9590. However, the FX-9590 was created with a 14 nm smaller manufacturing technology. Overall, by taking both into account, the Core i3-8300T 4-Core and the FX-9590 would appear to produce roughly the same amount of heat, and consume about the same amount of power.

CPU Mini Review

Mini ReviewThe Intel Core i3-8300T 4-Core 3.2GHz is a low-end power efficient CPU based on Intel's 8th Gen 14nm Coffee Lake S microarchitecture. It offers 4 physical cores (4 logical), clocked at 3.2GHz across all four cores. The i3-8300T doesn't have an unlocked multiplier, therefore, it can't be overclocked using traditional methods. It has 8MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. The Core i3-8300T has support for up to 64GB of dual-channel DDR4-2400 memory. It has a maximum Thermal Power Design of 35W, making it a very power efficient desktop processor. Among its many features are Intel Enhanced Speedstep, Turbo Boost 2.0, Virtualization, SSE3, AVX2 and SSE 4.2. It integrates Intel UHD Graphics 630 on board. It has a base frequency of 350MHz which can go up to 1.1GHz as well as offering DirectX 12 support. This CPU is likely to offer below average computational performance and will be a bottleneck in some of the most CPU-intensive AAA games from 2018 onward.FX-9590 is a high-end CPU based on the 32nm Piledriver architecture.

It offers 8 Physical Cores (8 Logical), initially clocked at 4.7GHz, which may go up to 5.0GHz and 8MB of L3 Cache.
Among its many features, Turbo Core and Virtualization are activated and the clock multiplier is unlocked, meaning it can be overclocked easily.

The processor DOES NOT have any integrated graphics, and has a rated board TDP of 220W.

Compared to its predecessor FX-8350 there's an overall 12% performance boost. Its performance is exceptionally good and enough for even the most demanding applications.
