High CPU Usage from Youtube?

So I recently noticed that Youtube was using a lot of CPU resources, which I thought was abnormal. I was reaching about 3-5% CPU resources idling with ~8 chrome tabs. The instant I opened a single youtube tab and played a video, CPU usage spiked to around 25% on my 3610qm. Is this normal? (It's also increasing CPU temperatures as well.)

 

This is normal with Chrome because its hardware acceleration sucks so it mainly uses CPU when playing back video. Try the same video in IE11 and you'll notice that your CPU usage is lower and GPU usage is higher.

 

Yes video streaming is cpu intensive. My 4710mq actually can't stream 4k60fps as its too intensive. But that's normal.

 

I don't think anything can stream 4k 60fps using chrome right now.

 

Maybe like an extreme desktop cpu? I would hope a 5960x could.

 

Well if a 3.5GHz haswell i7 holds under 30fps in a 4K 60fps video (but it holds 30fps in a 4K 30fps video; don't even get me started on how retarded that is) then a 3GHz 5960X won't hold 60fps XD.

Of course, overclock it until the cows come home and maybe. But...

oh wait, I actually know somebody with a 5960X that they bought like 2 days ago.

>_>.... <_<....

I'll see what I can do.

 

What about a 4790k then if its clock speed based?

 

4790K isn't going to be able to do it. If clocking it at 3.5GHz doesn't let you get 30fps, you couldn't likely clock it high enough to get 60. The 5960x has a chance because it has double the processing power (cores/threads), but since its basic clockspeed is lower, it needs an overclock to keep up.

 

For what it's worth I am able to easliy stream 4k 60fps in Chrome on my 5820k @ 4.5



It's not stressing much out either. Internet connections aside I find it hard to believe you guys are having trouble on quadcores at reasonable clocks.

 

Well that's a good 2x as fast as most CPUs ppl have in their laptops. What's your CPU usage like during playback?

 

I was trying to gauge it quickly and unscientifically before I left for work. Threads and cores were mainly around 20% with a split second spike to 75%. Not sure if that was from other background processes though.

 

This is the reason I look forward to Edge in Windows 10. If there's one thing that Microsoft do really well in their web browsers it's hardware acceleration. IE11 makes much better use of the GPU when rendering videos than Chrome or Firefox. If the UI and navigation features weren't so clunky it'd be my default browser.

 

Plays fine for me on my M6700 in IE using Windows 8.1 CPU usage at ~20% as well, the CPU is running at a steady 3.4-3.42 GHz, the university's internet connection is having hiccups sometimes though. Aside from that, GPU usage is in the 25-30% range.

CPU usage in firefox is more in the 30-40% range though and the GPU is working a lot less, ~5%, not to mention that in IE the GPU was clocking at 800 MHz core 1000 MHz GDDR5 and the core is only at 400 MHz in firefox.

IE gets points for GPU acceleration.

I don't have Chrome installed, so I won't be trying it, but it seems that other browsers do fine with 4K in youtube so far on decent laptop quad cores.
