In terms of overall gaming performance, the Intel Core i3-9100F 4-Core 3.6GHz is massively better than the AMD Athlon II X3 425 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 i3-9100F 4-Core was released over three years more recently than the Athlon II X3, and so the Core i3-9100F 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Athlon II X3 when running the latest games.

The Core i3-9100F 4-Core has 1 more core than the Athlon II X3. With 4 cores, the Core i3-9100F 4-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

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 Athlon II X3 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 i3-9100F 4-Core has a 0.9 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 Core i3-9100F 4-Core 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 Athlon II X3 has a 512 KB bigger L2 cache than the Core i3-9100F 4-Core, and although the Athlon II X3 does not appear to have an L3 cache, its larger L2 cache means that it wins out 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 i3-9100F 4-Core has a 30 Watt lower Maximum TDP than the Athlon II X3, and was created with a 31 nm smaller manufacturing technology. What this means is the Core i3-9100F 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 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 Athlon II series is based on the AMD K10 architecture and derived from the Phenom II series. However, unlike its Phenom siblings, it does not contain any L3 Cache. There are two Athlon II dies: the dual-core Regor die with 1 MB L2 Cache per core and the four-core Propus with 512 KB per core. Regor is a native dual-core design with lower TDP and additional L2 to offset the removal of L3 cache. The three core Rana is derived from the Propus quad-core design, with one core disabled.
