In terms of overall gaming performance, the Intel Core i9-9880H 8-Core 2.3GHz is massively better than the Intel Core i7-7920HQ 4-Core 3.1GHz 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 i9-9880H 8-Core was released over a year more recently than the Core i7-7920HQ 4-Core, and so the Core i9-9880H 8-Core is likely to have better levels of support, and will be more optimized for 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 i9-9880H 8-Core has 4 more cores than the Core i7-7920HQ 4-Core. 8 cores is probably excessive if you mean to just run the latest games, as games are not yet able to harness this many cores. The cores in the Core i7-7920HQ 4-Core is more than enough for gaming purposes. However, if you intend on running a server with the Core i9-9880H 8-Core, it would seem to be a decent choice.

The Core i9-9880H 8-Core has 8 more threads than the Core i7-7920HQ 4-Core. Both the Core i9-9880H 8-Core and the Core i7-7920HQ 4-Core use hyperthreading. The Core i9-9880H 8-Core has 2 logical threads per physical core and the Core i7-7920HQ 4-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 i9-9880H 8-Core and Core i7-7920HQ 4-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 i7-7920HQ 4-Core has a 0.8 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 i9-9880H 8-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.

Both the Core i9-9880H 8-Core and the Core i7-7920HQ 4-Core have the same TDP of 45 Watts, and were created with the same manufacturing size of 14 nm, which means they will affect your yearly electricity bill about equally.

The Core i9-9880H 8-Core and the Core i7-7920HQ 4-Core 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 i9-9880H 8-Core 2.3GHz is a high-end CPU based on Intel's 14nm Coffee Lake refresh microarchitecture. It offers 8 physical cores (16 logical), initially clocked at 2.3GHz, which may go up to 4.7GHz using Turbo Boost. It does not feature an unlocked multiplier and therefore cannot be overclocked using traditional methods. It has 16MB of L3 Cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. It also has 2MB L2 cache and 512KB L1 cache. This processor also supports DDR4 based RAMs with maximum memory support of 128GB. It has a maximum Thermal Power Design of 45W (including the onboard GPU). It is a fairly power efficient processor. Among its many features, HyperThreading, Turbo Boost 2.0 and Virtualization are activated are enabled. It features Intel UHD Graphics 630 integrated GPU with 350MHz base clock and turbo boost frequency of 1.2GHz. Video memory will depend on the amount of RAM paired with CPU but the maximum limit is 64GB.The Core i7-7920HQ 4-Core 3.1GHz is a power efficient mobile CPU based on the 14nm, Kaby Lake architecture. It offers 4 physical cores and 8 threads, initially clocked at 3.1GHz, which may go up to 4.1GHz and 8MB of L3 Cache. Among its many features, HyperThreading, Turbo Boost and Virtualization are activated. The processor integrates Graphics called Intel HD 630, initially clocked at 350MHz and that go up to 1.1GHz, 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 45W. Its performance is very good and will not the bottleneck in modern AAA games.
