Core Ultra X9 388H vs Core i9 14900KS: which should you choose?

Core Ultra X9 388H — 16-core Intel processor (4P+12E) scoring 132 single-core and 1343 multi-core in Cinebench 2024, with a 15 W TDP.

Core i9 14900KS — 24-core Intel processor (8P+16E) scoring 144 single-core and 2443 multi-core in Cinebench 2024, with a 150 W TDP and 36 MB L3 cache.

Core Ultra X9 388H vs Core i9 14900KS: Core i9 14900KS leads in multi-core performance. Core Ultra X9 388H is slower than Core i9 14900KS by 8.3% in single-core and slower by 45.0% in multi-core (Cinebench 2024). Core Ultra X9 388H draws less power (15W 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 132, 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 1,343 in Cinebench 2024. Its 24 cores (8 performance + 16 efficiency) give it real headroom for heavy parallel jobs.

Power and platform

The Core Ultra X9 388H is the more efficient chip at 15 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. Figures reflect the leaderboard snapshot on the page date.
