Our Verdict on Each
An incredibly efficient 6-core CPU that delivers excellent everyday desktop performance with near-silent operation, perfect for compact builds.
Best for: Building a silent or compact PC where heat output is the primary concern.
Read the full reviewA slight step up from the 12500, offering higher clock speeds for a noticeable bump in single-core performance.
Best for: The Core i5-12600 is an excellent buy for users seeking strong out-of-the-box performance without overclocking. Its higher base and boost clocks over the i5-12500 make it slightly better for gaming. If you need integrated graphics for troubleshooting or basic display tasks, this CPU covers you. However, if you plan to buy a dedicated GPU immediately and want to save money, the i5-12400F is a better value. However, if you value the higher clock speeds and UHD 770 graphics, the 12600 is a well-rounded investment that won't bottleneck mid-range GPUs. Pair it with a B660 motherboard for optimal cost efficiency and features.
