In terms of overall gaming performance, the Intel Core i3-10300T 4-Core 3.00GHz is massively better than the Intel Core i3-7100 2-Core 3.9GHz 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 i3-10300T 4-Core was released over three years more recently than the Core i3-7100 2-Core, and so the Core i3-10300T 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i3-7100 2-Core 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 Core i3-10300T 4-Core has 2 more cores than the Core i3-7100 2-Core. With 4 cores, the Core i3-10300T 4-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The Core i3-10300T 4-Core has 4 more threads than the Core i3-7100 2-Core. Both the Core i3-10300T 4-Core and the Core i3-7100 2-Core use hyperthreading. The Core i3-10300T 4-Core has 2 logical threads per physical core and the Core i3-7100 2-Core has 2.

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 i3-10300T 4-Core and Core i3-7100 2-Core 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 i3-7100 2-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 i3-10300T 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 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 i3-10300T 4-Core has a 16 Watt lower Maximum TDP than the Core i3-7100 2-Core (though they were created with the same size 14 nm manufacturing technology). What this means is the Core i3-10300T 4-Core will consume slightly less power and consequently produce less heat, enabling more prolonged computational tasks with fewer adverse effects. This will lower your yearly electricity bill slightly, as well as prevent you from having to invest in extra cooling mechanisms (unless you overclock).

The Core i3-10300T 4-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 i3-7100 2-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 i3-10300T 4-Core 3.00GHz is a CPU based on a refinement of the 14nm++ Comet Lake-S microarchitecture. It offers 4 physical cores (8 logical), initially clocked at 3.00 GHz, which may go up to 3.90 GHz using 4 cores with Turbo Boost. The Core i3-10300T has 8MB of L3 Cache.The Core i3-7100 2-Core 3.9GHz is a high-end CPU based on Intel's 7th Gen 14nm, Kaby Lake microarchitecture. It offers 2 physical cores (4 logical), clocked at 3.9GHz. It doesn't have an unlocked multiplier, therefore, it can't be overclocked using traditional methods. It has 3MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 51W. It is on par with competitor processors. Among its many features, Intel Enhanced Speedstep, HyperThreading and Virtualization are activated. Turbo Boost is not activated. It integrates Intel HD Graphics 630 on board. It has a base frequency of 350MHz which can go up to 1GHz as well as offer DirectX 12 support. This CPU is likely to offer good computational performance but may suffer from performance dips on higher resolutions and demanding applications.
