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.

A reliable workhorse in its day, the i5-6500 delivered excellent value for locked mainstream builds, though its 4-thread limitation renders it obsolete for modern heavy workloads.

Best for: The i5-6500 is only viable today if you are repairing an older LGA 1151 system on an extreme budget or building a basic home server. It can handle web browsing, office applications, and retro or esports gaming adequately. However, buying one new or even used at a high price makes no sense. Modern entry-level chips like the i3-12100F obliterate it in single-core and multi-core performance while offering a modern platform with an upgrade path. If you already own this chip, keep it as long as your tasks remain basic, but do not invest money into this platform expecting a noticeable uplift over your existing setup without moving to a newer generation.
