Intel's flagship $589 Core Ultra 9 285K headlines its new Arrow Lake' Core Ultra 200S series, leading the charge with 24 cores melded into a completely new chiplet architecture that comes with plenty of new leading-edge tech, like 3D Foveros packaging, support for new DDR5 CUDIMM memory tech, and the first dedicated AI engine fused inside a desktop PC chip.

Intel says it has root-caused the problems plaguing its Arrow Lake processors and that performance-boosting updates are now available.

Linux might be the better operating system for Arrow Lake CPUs, as the Core Ultra 9 285K runs faster in the latest version of Ubuntu than it does Windows 11 24H2.
