Core Ultra 9 285H Specifications

BGA16 cores / 16 threads

Intel's flagship Arrow Lake-H part for premium laptops: six Performance cores, eight Efficient cores and two Low Power Efficient cores make 16 total, running 16 threads since Hyper-Threading is dropped from this generation. Boost reaches 5.4GHz with 24MB of Smart Cache, inside a 45W base power that peaks at 115W maximum turbo. The Arc 140T integrated GPU and an onboard NPU aim it at thin, AI-capable laptops rather than desktop-class thermals.

3rd of 23 models in the Laptop CPU catalog on Boost clock. Tied 3rd of 23 models in the Laptop CPU catalog on L3 cache — 6 models share this figure.

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 14, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Reviewers report strong single-core and multi-core performance that keeps the chip competitive with AMD's best mobile offerings, with especially quick everyday responsiveness.
  • Its Arc 140T integrated GPU is singled out as one of the most capable integrated graphics tested, handling 1200p gaming at usable frame rates.
  • Efficiency is described as genuinely improved, with light office and video workloads sipping battery and performance barely dropping on battery power.

Commonly criticised

  • Its 13 TOPS NPU falls short of the Copilot+ threshold and leaves the entire H and HX line behind AMD and Qualcomm on AI capability.
