Our Verdict on Each

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.

Offers the best single-thread performance of the locked 7th Gen i5s, but the 4-core/4-thread limitation makes it a poor choice for modern multi-threaded workloads.

Best for: Upgrading an older LGA 1151 system where maximum single-thread speed is needed without overclocking.
