Is this throttling in the chip itself? Or is it something that e.g. Linux (the kernel) needs to be taught specifically for make/model? Or some combination of the two? And is it possible that the in-chip limiter is more of an emergency limit, and hitting it regularly can result in long term consequences if the kernel doesn't do aggressive enough limiting?

I just see really different behavior with heat, fans, and kernel behavior between XNU vs Linux, and Windows vs Linux on the same hardware.

After seeing those benchmarks, I'm feeling even better about having just decided to go for an Aero 15.

I quite like Mac laptops, but I've concluded that I don't really need one. I'll just grab one of the new (rumored) Mac minis to continue MacOS development as needed.

The heat off that MBP reminds me of how hot my early 2011 15" MBP got. I suspect that the heat was the culprit for the GPU failures that gave the 2011 model its notoriety.

I thought that was gpu manufacturer issue? I recall Nvidia specifically had a lot of issues across many oems.

It was likely a bit of both, but there's one thing that can't be denied, apple products are built for form over function.

I keep seeing thermal issues come back to bite some of the smartest companies with products designed by the world's best engineers. Everything from batteries to laptops to phones is severely affected by heat, and improper thermal design can lead to some huge issues. For example, the biggest thing affecting battery life is thermal load. The biggest thing affecting the maximum sustained power of a laptop or phone is th…

That's really interesting. Do you have any suggestions on some further reading?

Macbook “Pro”.

This! They ought to rename it, and actually sell a professional laptop.

That would require a complete and total culture change. As it is, and I know Apple has a war chest, the clock is ticking on their survival.

"Pro" is a pretty broad term. I suspect the MacBook Pro is powerful enough for most professionals who need a computer to do their jobs. I use one professionally for software development, and it suits my needs just fine.

Sure - there are some professions out there that require more power than a MacBook Pro can offer. But is it really fair to say it's not "Pro" just because it can't meet the needs of 100% of all working professionals?

Macs dont even start running fans until you hit >80C.

I think the correct terminology is “don’t start running the fans at high(audible) speeds till >80C.

Apparently they don't start at all until 80C here: https://www.youtube.com/watch?v=wgeh7ZJRhZU
