Core i9 12900HX vs Core Ultra 7 265HX: which should you choose?

Core i9 12900HX — 16-core Intel processor (8P+8E) scoring 112 single-core and 1269 multi-core in Cinebench 2024, with a 45 W TDP.

Core Ultra 7 265HX — 20-core Intel processor (8P+12E) scoring 125 single-core and 1598 multi-core in Cinebench 2024, with a 45 W TDP.

Core i9 12900HX vs Core Ultra 7 265HX: Core Ultra 7 265HX leads in multi-core performance. Core i9 12900HX is slower than Core Ultra 7 265HX by 10.4% in single-core and slower by 20.6% in multi-core (Cinebench 2024).

Gaming and single-threaded work

Games and everyday responsiveness lean on single-core speed. The Core Ultra 7 265HX leads there with a single-core score of 125 versus 112, 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 Ultra 7 265HX is stronger, posting 1,598 multi-core against 1,269 in Cinebench 2024. Its 20 cores (8 performance + 12 efficiency) give it real headroom for heavy parallel jobs.

Power and platform

The Core i9 12900HX is the more efficient chip at 45 W versus 45 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.
