In terms of overall gaming performance, the Intel Core i3-8300T 4-Core 3.2GHz is massively better than the AMD Phenom II X4 905e 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 Phenom II X4, 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 Phenom II X4 when running the latest games.

The Core i3-8300T 4-Core and the Phenom II X4 both have 4 cores, which is not likely to be a limiting factor for gaming.

Both the Intel Core i3-8300T 4-Core 3.2GHz and the AMD Phenom II X4 905e have the same number of threads. 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 Phenom II X4 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 Core i3-8300T 4-Core has a 0.7 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 Phenom II X4 has a 1024 KB bigger L2 cache than the Core i3-8300T 4-Core, but on the other hand, it is the Core i3-8300T 4-Core that has a 2 MB bigger L3 cache than the Phenom II X4. In this case, the L2 size is probably what counts, so the Phenom II X4 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 i3-8300T 4-Core has a 30 Watt lower Maximum TDP than the Phenom II X4, and was created with a 31 nm smaller manufacturing technology. What this means is the Core i3-8300T 4-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).

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.Phenom II X4 905e is an energy efficient processor based on the 45nm, K10 architecture.

It offers 4 Physical Cores (4 Logical), clocked at 2.5GHz and 6MB of L3 Cache.
Among its many features, Virtualization is activated and the clock multiplier is unlocked, meaning it can be overclocked easily.

The processor DOES NOT integrate any graphics. and has a rated board TDP of 65W.

It offers average performance. This means it will become a bottleneck in some demanding applications.
