In this review, we're testing the Core i5-8400, which is extremely interesting given its $190 price tag as it's the first six-core Intel processor under the $200 mark. Its clock speeds may be rather restrained, and you lose out on the overclocking feature of the pricier i5-8600K, but six cores should still amount to something.

Intel Core i5-8400 Final Verdict Overall, the Intel Core i5-8400 is a great choice for gamers specifically. Given the price point of around $200, someone looking to build a gaming PC will be very satisfied with this CPU. It provides near i7 performance in games, while nearly half the price.

Tom's Hardware Verdict The Core i5-8400 brings a powerful six-core design to the mid-range, offering class-leading gaming performance and competitive performance in heavier applications. More expensive models offer more performance in both categories, but the Core i5-8400 is easily the pound-for-pound gaming champion.

Integrated graphics made the Core i5 8400 a decent choice for professional systems, while the improved performance made it one of the best budget gaming CPUs on the market. The lack of manual overclocking potential is a shame, but the quality of Intel Turbo Boost largely makes up for it.
