Are CPUs with more cores better for gaming?
CPUs with more cores are not always better for gaming. Most modern games make efficient use of between 4 and 8 cores. A large number of cores can be useless if the game is not designed to exploit them. Processor frequency, finesse and architecture are often more important, as they directly influence the performance of gameplay-related tasks. For the majority of gamers, a processor with 6 to 8 high-performance cores is sufficient, except in the case of intensive multitasking such as streaming or video editing in parallel.
How to choose the right processor for gaming?
The best gaming processors (CPUs) for PCs in 2025 are distinguished by their optimized processor architecture, clock frequency (expressed in MHz) and number of cores (dual-core, quad-core, hexa or even more). Whether you opt for a powerful Intel Core processor (e.g. Core i3, Core i7 or a more recent generation) or an AMD Ryzen processor, the most important thing is to check the chip’s compatibility with your motherboard (socket, chipset, BIOS) and RAM.
The balance between processor power and graphics cards (NVIDIA GeForce GTX or AMD Radeon) is crucial for smooth visuals at Full-HD and beyond. Intel processors, whether from older ranges (Sandy Bridge, Ivy Bridge) or more recent generations, often feature Turbo Boost technology to increase processor frequency according to processor load. AMD processors offer similar features for overclocking the processor and taking advantage of every available thread.
To identify the best processor for your needs, it’s a good idea to consult a benchmark or price comparison site, and look at benchmarks and cache memory (L2 cache, or even more). Also consider thepower supply (in watts) and cooling: a high-performance ventirad or suitable fan will prevent the more powerful processor from overheating. Recent motherboards generally feature PCI-Express ports, essential for accommodating a high-end GPU (graphics card) and benefiting from an optimized configuration.
Depending on your budget, you can aim for an entry-level or mid-range processor, or even a new processor specially designed for demanding games. Intel Pentium or AMD Athlon processors are suitable for a more modest configuration, while high-end Intel Core i7 or AMD Ryzen processors are aimed at gamers looking for the best processor performance. A gamer PC equipped with a dedicated processor and sufficient RAM will offer you a significant gain in fluidity and power for all your favorite 2025 titles.
