The Intel Core Ultra 9 285 is a 24-core desktop processor with 8 Performance-cores and 16 Efficient-cores, boosting up to 5.6 GHz. It suits high-performance desktop builds for demanding multitasking and productivity; it uses an LGA 1851 motherboard with an Intel 800-series chipset.

Recommended For

  • Desktop users who regularly run CPU-heavy work—such as compiling code, rendering, or processing large exports—alongside other open applications. Its 24-core layout suits parallel workloads, though results vary by application.
  • Organizations building managed business desktops that can use Intel vPro features, including remote management and security tools, with a compatible system configuration.
  • Builders assembling a new LGA1851 desktop workstation who want many CPU cores, DDR5 support, and integrated graphics for display output or basic troubleshooting before installing a discrete GPU.
  • Users moving between demanding desktop workloads and gaming who prioritize multi-threaded work over leading CPU-limited gaming frame rates, and plan to pair the processor with a discrete graphics card.
