In terms of overall gaming performance, the Intel Core i3-9100T 4-Core 3.1GHz is massively better than the Intel Pentium Dual Core G6951 2.8GHz 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 i3-9100T 4-Core was released over three years more recently than the Pentium Dual Core, and so the Core i3-9100T 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Pentium Dual Core when running the latest games.

The Core i3-9100T 4-Core has 2 more cores than the Pentium Dual Core. With 4 cores, the Core i3-9100T 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 i3-9100T 4-Core and Pentium Dual 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 i3-9100T 4-Core has a 0.3 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 enough that it possibly indicates the superiority of the Core i3-9100T 4-Core.

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 i3-9100T 4-Core has a 512 KB bigger L2 cache than the Pentium Dual Core, which means that it, at worst, wins out in this area, and at best, will provide superior gaming performance and will work much better with high-end graphics cards.

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 i3-9100T 4-Core has a 38 Watt lower Maximum TDP than the Pentium Dual Core, and was created with a 18 nm smaller manufacturing technology. What this means is the Core i3-9100T 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).

The Core i3-9100T 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 Pentium Dual 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 i3-9100T 4-Core 3.1GHz is a low-end desktop CPU based on a refinement of the 14nm++ Coffee Lake microarchitecture. The 'T' suffix designates a low power draw variant of the Core i3-9300. It offers 4 physical cores (4 logical), initially clocked at 3.1GHz, which may go up to 3.7GHz using 4 cores with Turbo Boost. The i3-9100T 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 i3-9100T CPU offers below average gaming performance in 2019 and may be 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, although may struggle with the most demanding AAA titles. Performance may become bottlenecked if playing at 144Hz and 1080p or lower screen resolution.1. Note that these are also dual core, but under the Pentium brand. 2. Based on Westmere microarchitecture 3. All models support: MMX, SSE, SSE2, SSE3, SSSE3, Enhanced Intel SpeedStep Technology (EIST), Intel 64, XD bit (an NX bit implementation), Intel VT-x, Smart Cache. 4. G6951 can be unlocked to enable "extra features", which are present in the CPU but deliberately crippled, with the purchase of a $50 upgrade card.
