M2 Ultra vs Core i9 14900KS: Core i9 14900KS leads in multi-core performance. M2 Ultra is slower than Core i9 14900KS by 12.5% in single-core and slower by 21.5% in multi-core (Cinebench 2024). M2 Ultra draws less power (80W vs 150W base TDP).
Gaming and single-threaded work
Games and everyday responsiveness lean on single-core speed. The Core i9 14900KS leads there with a single-core score of 144 versus 126, 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 Core i9 14900KS is stronger, posting 2,443 multi-core against 1,918 in Cinebench 2024. Its 24 cores (8 performance + 16 efficiency) give it real headroom for heavy parallel jobs.
Power and platform
The M2 Ultra is the more efficient chip at 80 W versus 150 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.
