The Core Ultra 9 285K is Intel's flagship desktop CPU for the LGA1851 socket and 800-series motherboards. It pairs eight performance cores with sixteen efficiency cores, runs unlocked, and adds an NPU for on-device AI work alongside PCIe 5.0 and DDR5 support. It suits gamers and creators who want strong multi-threaded throughput and modern connectivity. Against AMD's X3D chips it trails in some games, and early firmware held back its full performance, but it is a capable all-rounder for heavy multitasking and content work.
