In terms of overall gaming performance, the Intel Core i7-7700HQ 4-Core 2.8GHz is massively better than the Intel Core i5-2430M 2.4GHz 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 i5-2430M 2.4GHz was released less than a year after the Core i7-7700HQ 4-Core, and so they are likely to have similar levels of support, and similarly optimized performance when running the latest games.

The Core i7-7700HQ 4-Core has 2 more cores than the Core i5-2430M 2.4GHz. With 4 cores, the Core i7-7700HQ 4-Core is much less likely to struggle with the latest games, or bottleneck high-end graphics cards when running them.

The Core i7-7700HQ 4-Core has 4 more threads than the Core i5-2430M 2.4GHz. Both the Core i7-7700HQ 4-Core and the Core i5-2430M 2.4GHz use hyperthreading. The Core i7-7700HQ 4-Core has 2 logical threads per physical core and the Core i5-2430M 2.4GHz 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 i7-7700HQ 4-Core and Core i5-2430M 2.4GHz 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 i7-7700HQ 4-Core has a 0.4 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 i7-7700HQ 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 i7-7700HQ 4-Core has a 512 KB bigger L2 cache than the Core i5-2430M 2.4GHz, 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 i5-2430M 2.4GHz has a 10 Watt lower Maximum TDP than the Core i7-7700HQ 4-Core. However, the Core i7-7700HQ 4-Core was created with a 18 nm smaller manufacturing technology. Overall, by taking both into account, the Core i7-7700HQ 4-Core is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

The Core i7-7700HQ 4-Core and the Core i5-2430M 2.4GHz 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.

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 i7-7700HQ 4-Core 2.8GHz is a power efficient mobile CPU based on the 14nm, Kaby Lake architecture. It offers 4 physical cores and 8 threads, initially clocked at 2.8GHz, which may go up to 3.8GHz and 6MB 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 sufficient for most modern gamingCore i5-2430M 2.4GHz is a middle-class mobile processor based on the 32nm, Sandy Bridge architecture.

It offers 2 Physical Cores (4 Logical), initially clocked at 2.4GHz, which may go up to 3.0GHz and 3MB of L3 Cache.
Among its many features, Turbo Boost and Virtualization are activated.

The processor integrates weak Graphics called Intel HD Graphics 3000, with 12 Execution Units, initially clocked at 650MHz and that go up to 1200MHz, 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.
