Apple M3 vs Intel Core i9-12900K: which should you choose?

Apple M3 — 8-core / 8-thread Apple laptop processor (2023) with a boost clock of 4.05 GHz and 22 W TDP.

Intel Core i9-12900K — 16-core / 24-thread Intel desktop processor (2021) with a boost clock of 5.2 GHz and 125 W TDP.

Apple M3 vs Intel Core i9-12900K: Intel Core i9-12900K leads in multi-core performance. Apple M3 is faster than Intel Core i9-12900K by 15.1% in single-core and slower by 28.7% in multi-core. Apple M3 also draws less power (22W vs 125W).

Gaming and single-threaded work

Games and everyday responsiveness lean on single-core speed. The Apple M3 leads there with a single-core score of 3,050 versus 2,650, 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 Intel Core i9-12900K is stronger, posting 16,400 multi-core against 11,700. Its 16 cores and 24 threads give it real headroom for heavy parallel jobs.

Power and platform

The Apple M3 is the more efficient chip at 22 W versus 125 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.
