Our Verdict on Each

By removing the integrated graphics, Intel created a highly affordable 6-core CPU that maximizes value for gamers who already own a discrete GPU.

Best for: The Intel Core i5-10400F is highly recommended for budget-conscious gamers building a 1080p system with a dedicated graphics card. By cutting out the integrated graphics, it saves money that can be better spent on a stronger GPU, making it an ideal pairing for cards like the GTX 1660 Super or RTX 3060. Its 6-core, 12-thread design ensures it won't bottleneck mid-range GPUs in most modern games. Because it is locked, you don't need to spend extra on Z-series motherboards or fancy coolers; a B460 board and stock cooling are perfectly adequate. It is perfect for students or first-time builders who want a reliable, plug-and-play experience. Avoid it only if you absolutely need integrated graphics as a fallback or if you plan on overclocking.
