What amazes me is that so much a M2 Mac's resources would be used to render a website even if it rendered everything from scratch. There is almost no graphic content compared to a video game produced decades ago, and they would easily render a frame in 1/2 the time on decades old hardware

Well, raw graphical content is the easy part.

A live layout tree that has to be repainted and composited yet intersect with arbitrary layers like an accessibility tree and what would naively be N:N style calculations is completely different architecture.

Consider examples where people toy with the concept of replacing the DOM with a canvas but basic things like text selection don't even work anymore.

Keep in mind that the percentage in Activity Monitor is 100 % per core, so a 10 core CPU can go up to 1000 % usage. So 60 % means 60 % of a single core not of the whole CPU.

And it's sensitive to dynamic scaling as well, isn't it? So it's possibly not 60% of a core at max clock, but maybe of a core clocked to 800mhz or something.

I fell for that shallow analysis myself once when I noticed just how apparently bad the gpu usage was for a big of animation in a web page, until I noticed my 30% load gpu still drew as much wattage as it did on idle.

So it's 60% of the battery optimal usage? So 10 cores can get to 2000%?

Videos game rarely do any complex dynamic layout. That is where all the time is going
