Our take on the Intel Core Ultra 9 285K

The Intel Core Ultra 9 285K is Intel's flagship desktop CPU for the LGA1851 socket. It has 24 cores (8 performance, 16 efficient) with 24 threads, boosts to 5.7 GHz, and uses a chiplet design that runs cooler and draws less power than the previous generation. Reviewers praise its strong multi-core performance and efficiency, but note that it trails the best gaming CPUs from AMD in some titles. It suits creators and multitaskers who want a fast, efficient all-rounder.
