Our Verdict on Each

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.

The i5-6600 was the ultimate locked gaming chip of 2015, boasting high boost clocks, though modern users will find its 4-thread design a major bottleneck.

Best for: The i5-6600 is a solid drop-in upgrade if you are currently running a Pentium or i3 on an LGA 1151 motherboard and can get this chip for dirt cheap. It offers a noticeable bump in single-core speed and cache over lower-tier Skylake chips, making your system feel much snappier for daily use and older games. It’s also a decent holdover chip if your main CPU died and you need a cheap replacement. However, buying this to build a new system is a mistake. Modern budget chips like the i3-12100F offer vastly superior single-thread and multi-thread performance, alongside modern platform features. Do not overspend on this legacy hardware; your money is better saved for a modern platform overhaul.
