In terms of overall gaming performance, the Intel Core i3-8100F 4-Core 3.6GHz is massively better than the Intel Celeron 667MHz 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 i3-8100F 4-Core was released over three years more recently than the Celeron 667MHz, and so the Core i3-8100F 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Celeron 667MHz when running the latest games.

The Core i3-8100F 4-Core has 3 more cores than the Celeron 667MHz. With 4 cores, the Core i3-8100F 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 i3-8100F 4-Core and Celeron 667MHz 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 i3-8100F 4-Core has a 2.933 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 i3-8100F 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 Core i3-8100F 4-Core has a 896 KB bigger L2 cache than the Celeron 667MHz, and although the Celeron 667MHz 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 i3-8100F 4-Core has a 110 Watt lower Maximum TDP than the Celeron 667MHz, and was created with a 166 nm smaller manufacturing technology. What this means is the Core i3-8100F 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 i3-8100F 4-Core 3.6GHz 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), initially clocked at 3.6GHz across all four cores. It is identical to the Core i3-8100 minus the integrated graphics chip. The i3-8100F doesn't have an unlocked multiplier, therefore, it can't be overclocked using traditional methods. It has 6MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. The Core i3-8000T has support for up to 64GB of dual-channel DDR4-2400 memory. It has a maximum Thermal Power Design of 65W. It is on par with competitor processors. Among its many features are Intel Enhanced Speedstep, Turbo Boost 2.0, Virtualization, SSE3, AVX2 and SSE 4.2. 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 2019 onward.The Celeron brand has been used by Intel for several distinct ranges of x86 CPUs targeted at budget personal computers. Celeron processors can run all IA-32 computer programs, but their performance is somewhat lower when compared to similar CPUs with higher-priced Intel CPU brands. For example, the Celeron brand will often have less cache memory, or have advanced features purposely disabled. These missing features have had a variable impact on performance. In some cases, the effect was significant and in other cases the differences were relatively minor. Many of the Celeron designs have achieved a very high bang for the buck, while at other times, the performance difference has been noticeable. This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron range.
