Core i9 14900KF — 24-core Intel processor (8P+16E) scoring 129 single-core and 2071 multi-core in Cinebench 2024, with a 125 W TDP and 36 MB L3 cache.
M3 Ultra vs Core i9 14900KF: M3 Ultra leads in multi-core performance. M3 Ultra is faster than Core i9 14900KF by 3.1% in single-core and faster by 32.9% in multi-core (Cinebench 2024). Core i9 14900KF draws less power (125W vs 140W base TDP).
Gaming and single-threaded work
Games and everyday responsiveness lean on single-core speed. The M3 Ultra leads there with a single-core score of 133 versus 129, 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 2,071 in Cinebench 2024. Its 32 cores (24 performance + 8 efficiency) give it real headroom for heavy parallel jobs.
Power and platform
The Core i9 14900KF 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.
