> Now everyone suffers from increased heat and power usage

Why?

And wasn't sgx removed from newer cpus anyways? At least in desktop/mobile space...

>Why?

because undervolting usually results in lower power draw/higher power efficiency

But they said "everyone" - I imagine undervolting would only be done by people trying to hack the sgx, or maybe try to save a bit of power. So I'd assume 99.99% of users would be unaffected? Or did the cpu undervolt automatically before the update?

FWIW I have undervolted every laptop I've ever had. It's a huge win in terms of battery life and often performance as well because you can avoid ever hitting the thermal envelope. It can be a 30% boost if you have good silicon.

Yes, and that also basically killed Blu-ray support on desktop, because DRM couldn’t be implemented in an acceptable matter otherwise. Fun thing of course is, that you can probably crack any Samsung or $random_cheap_brand Blu-ray player but there are too many of them so there isn’t any group focused on a “big fish to fry”.
