Intel Core Ultra 9 285K
Intel's no-compromise flagship: 24 cores/24 threads on LGA1851, boosting to 5.7GHz at 125W with integrated graphics. The 24-core count makes it a productivity powerhouse for heavy creation and compute. It is not the efficiency or gaming-first choice, though, as the data flags the 9800X3D leading for gaming and the chip being a poor fit for power-frugal small-form-factor builds.

Ecosystem
Standards
Form factors & standards — interchangeable across compatible builds, not a platform lock-in.
Compatibility
Built around DDR5, Intel LGA1851. Make sure the rest of your build uses the same platform before you buy — mismatched sockets, mounts or standards are the most common return reason. Check it in the builder →
Upgrade path
A top-tier cpu — there's little to upgrade to within the category.
