In terms of overall gaming performance, the Intel Core i3-8100H 4-Core 3.0GHz is massively better than the Intel Core i5-3210M 2.5GHz 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 i3-8100H 4-Core was released over three years more recently than the Core i5-3210M 2.5GHz, and so the Core i3-8100H 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i5-3210M 2.5GHz when running the latest games.

The Core i3-8100H 4-Core has 2 more cores than the Core i5-3210M 2.5GHz. With 4 cores, the Core i3-8100H 4-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

Both the Intel Core i3-8100H 4-Core 3.0GHz and the Intel Core i5-3210M 2.5GHz have the same number of threads. The Core i3-8100H 4-Core has one thread per physical core, whereas the Core i5-3210M 2.5GHz uses hyperthreading and has 2 logical threads 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 i3-8100H 4-Core and Core i5-3210M 2.5GHz 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 i3-8100H 4-Core has a 0.5 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 i3-8100H 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 i3-8100H 4-Core has a 512 KB bigger L2 cache than the Core i5-3210M 2.5GHz, 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 i5-3210M 2.5GHz has a 10 Watt lower Maximum TDP than the Core i3-8100H 4-Core. However, the Core i3-8100H 4-Core was created with a 8 nm smaller manufacturing technology. Overall, by taking both into account, the Core i3-8100H 4-Core is likely the CPU with the lower heat production and power requirements, but there really isn't much in it.

The Core i3-8100H 4-Core and the Core i5-3210M 2.5GHz both have an on-board GPU, which means that they will be capable of running basic graphics applications (i.e., games) without the need for a dedicated graphics card.

For an in-depth GPU comparison, click on the GPU comparison icon that you can find throughout Game-Debate:

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 Intel Core i3-8100H 4-Core 3.0GHz is a mid-range laptop CPU based on an enhanced version of Intel's 8th Gen 14nm++ Coffee Lake microarchitecture. It offers 4 physical cores (4 logical), clocked at 3.0GHz with no turbo boost capabilities. It 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. This processor also supports DDR4 based RAMs with maximum memory support of 32GB. It has a configurable Thermal Power Design, ranging from 35W at 2.6GHz up to 45W for 3.0 GHz. It is on par with competitor processors. Among its many features are Intel Enhanced Speed Shift, HyperThreading, Turbo Boost 20, and Virtualization Technology. It integrates Intel UHD Graphics 630 on board. It has a base frequency of 350MHz which can go up to 1.0GHz, as well as offering DirectX 12 support. This CPU is likely to offer below average computational performance and should be suitable to play most modern AAA games in 2019. It may be the bottleneck for games which favour strong threaded performance.Core i5-3210M 2.5GHz is a middle-class mobile processor based on the 22nm, Ivy Bridge architecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 2.5GHz, which may go up to 3.1GHz and 3MB of L3 Cache.
Among its many features, Turbo Boost and Virtualization are activated and the processor has multiplier unlocked.

The processor integrates mildly powerful Graphics called Intel HD Graphics 4000, with 16 Execution Units, initially clocked at 650MHz and that go up to 1100MHz, in Turbo Mode which share the L2 Cache and system RAM with the processor.
Both the processor and integrated graphics have a rated board TDP of 35W.

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