Core i9 12900HX vs M5: 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.
M5 — 10-core Apple processor (4P+6E) scoring 208 single-core and 1183 multi-core in Cinebench 2024, with a 27 W TDP.
Core i9 12900HX vs M5: Core i9 12900HX leads in multi-core performance. Core i9 12900HX is slower than M5 by 46.2% in single-core and faster by 7.3% in multi-core (Cinebench 2024). M5 draws less power (27W vs 45W base TDP).
Gaming and single-threaded work
Games and everyday responsiveness lean on single-core speed. The M5 leads there with a single-core score of 208 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 i9 12900HX is stronger, posting 1,269 multi-core against 1,183 in Cinebench 2024. Its 16 cores (8 performance + 8 efficiency) give it real headroom for heavy parallel jobs.
Power and platform
The M5 is the more efficient chip at 27 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.
