What reviewers say

Reviews find strong gaming performance and substantial overclocking headroom, with six cores improving on the previous four-core i5 generation. Value depends on price and workload; the cheaper i5-8400 can offer similar gaming results, while Ryzen's extra threads suit rendering. Overclocking improves CPU-heavy work more consistently than GPU-limited games and increases cooling and power demands.
