Core Ultra 9 285K Spec and Price in the United States

LGA185124 cores / 24 threads

Released October 10, 2024 · $599.00 MSRP

Intel's flagship Arrow Lake desktop part and its first LGA1851 socket: 24 cores split 8 Performance and 16 Efficient reach a 5.7GHz boost, backed by 36MB of L3 cache. Unlike the 14900K it replaces at the top of the stack, the 285K drops Hyper-Threading entirely, so its 24 threads match its core count rather than doubling on the P-cores. A 125W base power and 250W maximum turbo power pair with DDR5-6400 support and Intel Graphics for a fallback display. At $599 boxed, it targets buyers building around the newest desktop platform Intel ships.

Tied 5th of 65 models in the CPU catalog on Boost clock — 5 models share this figure. Tied 24th of 65 models in the CPU catalog on L3 cache — 6 models share this figure.

Guides for this category

How to choose a desktop CPUA chip's socket decides what it can go into; cores, cache and TDP decide what you actually get once it's installed.How many CPU cores you actually needWhy more cores is not more speed, how gaming and productivity ask for cores differently, and why a core count alone never ranks two chips.When a CPU price is actually goodWhy a chip's list price and discount percentage tell you little, what a processor's price does over its life, and how to read its tracked history.Laptop CPU vs desktop CPUA mobile chip with the same core count is not the same processor — what the power envelope changes, and why these parts carry no price.

What owners and reviewers say

Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • More energy efficient than before with great rendering performance and a built-in acceleration unit.

Commonly criticised

  • A costly new platform, not great at gaming, and only a sideways performance step.
