Our Verdict on Each

A highly cost-effective 6-core CPU that delivers excellent value for 1080p gaming and general computing, despite its locked multiplier and older 14nm process.

Best for: The Intel Core i5-10400 is highly recommended for users building a budget to mid-range 1080p gaming PC or a general-purpose home/office computer. Its 6-core, 12-thread configuration provides excellent longevity for everyday tasks, light content creation, and modern gaming when paired with a mid-range GPU like an RTX 3060 or RX 6600. The inclusion of UHD 630 graphics means the system is functional even if a discrete GPU fails or is delayed in purchase. Because it is a locked processor, there is no need to invest in expensive Z-series motherboards or high-end cooling; a simple B460 board and the stock cooler are sufficient. This makes it an ideal choice for budget-conscious buyers who prioritize stability, reliability, and maximum value over enthusiast-level tweaking or extreme frame rates.

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.
