Why is CPU usage low on YouTube in IE 11, but high in other browsers?

Question

YouTube

IE11

Yandex browser

In Chrome and Firefox, the same as in YaB (what with hardware acceleration, what without; what with NVIDIA, what with the CPU)

Answer 1

Because IE uses hardware acceleration, and a lot of developers in Google and Mozilla either can't or don't want to implement it in their browsers. Therefore, IE must have on all weak computers where hardware-accelerated video decoding is implemented. For example, on the n3450 processor, which is in many laptops and mini PCs, only IE saves the situation, YouTube even spins 4k smoothly (plus battery savings and no heat), while chrome and the rest can’t even 1080p60!

Answer 2

As already noted above - the point is in hardware video acceleration. I have been using Edge for YouTube for a long time, because even when watching 4k, the processor load is minimal. It saves battery power very well, and most importantly, the cooling system does not make noise while watching. Even on a dead Atom Z3735F, you can watch [email protected] without dropping frames:

I have never seen anything like it on Mac, let alone Linux.
To achieve similar results in Chrome, you can install the h264ify extension, which will force the default VP9 codec for Chrome to be switched to H.264. This will offload the processor, but with this extension it will not be possible to set the quality above 1080p.

Answer 3

what exactly is bothering you? ie does not actually contain anything. and the other listed browsers on webkit are, in fact, a kind of combine functionality in addition to the browser. well, it is logical that such applications and resources will eat accordingly

Answer 4

Probably because IE does not have a billion extensions and additions, as in the same chrome or FF
