Core Ultra 9 285K vs M3 Ultra: which should you choose?

Core Ultra 9 285K — 24-core Intel processor (8P+16E) scoring 141 single-core and 2261 multi-core in Cinebench 2024, with a 125 W TDP and 36 MB L3 cache.

M3 Ultra — 32-core Apple processor (24P+8E) scoring 133 single-core and 2753 multi-core in Cinebench 2024, with a 140 W TDP.

Core Ultra 9 285K vs M3 Ultra: M3 Ultra leads in multi-core performance. Core Ultra 9 285K is faster than M3 Ultra by 6.0% in single-core and slower by 17.9% in multi-core (Cinebench 2024). Core Ultra 9 285K draws less power (125W vs 140W base TDP).

Gaming and single-threaded work

Games and everyday responsiveness lean on single-core speed. The Core Ultra 9 285K leads there with a single-core score of 141 versus 133, so it is the marginally better pick for high-refresh gaming — though at typical resolutions the GPU usually decides frame rates.

Content creation and multitasking

For rendering, compilation, video export and other all-core workloads, the M3 Ultra is stronger, posting 2,753 multi-core against 2,261 in Cinebench 2024. Its 32 cores (24 performance + 8 efficiency) give it real headroom for heavy parallel jobs.

Power and platform

The Core Ultra 9 285K is the more efficient chip at 125 W versus 140 W, which means less heat, quieter cooling and lower running costs under sustained load.

The verdict

Both are credible choices in the processor comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology

Processors are compared on Cinebench 2024 single-core and multi-core scores from published leaderboard results, alongside core configuration (performance + efficiency cores), base TDP, L3 cache, PassMark CPU Mark, 1080p gaming scores and street pricing where measured. Cinebench reflects rendering-style workloads; gaming performance depends heavily on the GPU and the specific title, so treat single-core standing as directional. Figures reflect the leaderboard snapshot on the page date.
