M3 Ultra vs Core Ultra 5 250K Plus: which should you choose?

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 5 250K Plus — 18-core Intel processor (6P+12E) scoring 139 single-core and 1853 multi-core in Cinebench 2024, with a 125 W TDP and 30 MB L3 cache.

M3 Ultra vs Core Ultra 5 250K Plus: M3 Ultra leads in multi-core performance. M3 Ultra is slower than Core Ultra 5 250K Plus by 4.3% in single-core and faster by 48.6% in multi-core (Cinebench 2024). Core Ultra 5 250K Plus 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 5 250K Plus leads there with a single-core score of 139 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 1,853 in Cinebench 2024. Its 32 cores (24 performance + 8 efficiency) give it real headroom for heavy parallel jobs.

Power and platform

The Core Ultra 5 250K Plus 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.
