Intel Core i5-12400F vs Apple M3: which should you choose?
Intel Core i5-12400F — 6-core / 12-thread Intel desktop processor (2022) with a boost clock of 4.4 GHz and 65 W TDP.
Apple M3 — 8-core / 8-thread Apple laptop processor (2023) with a boost clock of 4.05 GHz and 22 W TDP.
Intel Core i5-12400F vs Apple M3: Apple M3 leads in multi-core performance. Intel Core i5-12400F is slower than Apple M3 by 22.0% in single-core and slower by 21.4% in multi-core. Apple M3 draws less power (22W vs 65W).
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 2,380, 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 Apple M3 is stronger, posting 11,700 multi-core against 9,200. Its 8 cores and 8 threads give it real headroom for heavy parallel jobs.
Power and platform
The Apple M3 is the more efficient chip at 22 W versus 65 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.
