It’s all about the perf per watt.

Mac on intel feels like it was about 2x slower at these basic functions. (I don’t have real data points)

Intel Mac had lag when opening apps. Silicon Mac is instant and always responsive.

No idea how that compares to Linux.

Apples CPUs are most powerful efficient however, due to a bunch of design and manufacturing choices.

But to answer your question, yes Windows 11 with modern security crap feels 2-3 slower than vanilla Linux on the same hardware.

When Apple released Apple Silicon, it was a huge breath of fresh air - suddenly the web became snappy again! And the battery lasted forever! Software has bloated to slow down MacBooks again, RAM can often be a major limiting factor in performance, and battery life is more variable now.

Intel is finally catching up to Apple for the first time since 2020. Panther Lake is very competitive on everything except single-core performance (including battery life). Panther Lake CPU's arguably have better features as well - Intel QSV is great if you compile ffmpeg to use it for encoding, and it's easier to use local AI models with OpenVINO than it is to figure out how to use the Apple NPU's. Intel has better tools for sampling/tracing performance analysis, and you can actually see check you're loading the iGPU (which is quite performant) and how much memory you're using. The iGPU's can also be configured to use varying amounts of system RAM - I'm not sure how that compares to Apple's unified memory for effective VRAM, and Apple has higher memory bandwidth/lower latency.

I'm not saying that Intel has matched Apple, but it's competitive in the latest generation.
