Our Verdict on Each
Simply the best value high-end CPU on the market. It dominates gaming, crushes productivity, and overclocks beautifully.
Best for: The Core i5-13600K is the definitive recommendation for high-end PC builders who want maximum performance without paying flagship taxes. It is perfect for gamers pairing with RTX 4080 or RX 7900 XTX GPUs, as well as content creators who need robust multi-threaded rendering. Because it is unlocked, it rewards users willing to invest in a Z790 motherboard and a high-end AIO liquid cooler with exceptional overclocking headroom. It should be purchased by anyone who values performance-per-dollar above all else. The only users who should avoid it are those on strict budgets (who should look at the 13400F or 13500) or those building completely silent, low-power systems. The 13600K demands robust cooling and a capable power supply, but in return, it delivers a level of performance that redefines the mid-range segment.
Read the full reviewA capable 8-core CPU that trades raw clock speed for significantly lower power consumption, ideal for specific use cases where efficiency and thermals matter more than maximum performance.
Best for: Building or upgrading a very quiet, small form factor PC where low power and heat are critical, and the CPU can be found at a significant discount.
