Can your PC stream 8k 60fps videos without stuttering? It's more demanding than you think!

I first tried this with a desktop that had a i7 6700k stock and a AMD 7850.
The video would play, but only at about 10fps and the poor 6700k and 7850 were at 100% load

Still waiting for the 3950x, so tested this with the second system

8700k 5ghz
2080ti

70% CPU load and 30% GPU load, but at least the video is a smooth 60fps on this system even if it's very taxing!

 
Yeah, zero dropped frames with an 1800X and a 2070 Super. The CPU is essentially idle though, since the GPU is doing all the heavy lifting. The video engine portion is at ~75% usage according to GPU-Z. Also using Firefox, though I don't know it makes any difference.
 
How can you tell if its working properly, seems to play smoothly on my work PC, CPU not utilised much, GPU about 70%......8700(non k) with an onboard intel gpu....
 
Try running two copies then, on my PC having two tabs with the video playing I got 100% CPU load and 50% GPU load and both videos just stutter like crazy
 
No problem here , smooth as anything.

Using standard Microsoft Edge.

GPU is about 75% utilisation
CPU barely tickled at about 5%

3700X / 2080 Super

I can run two side by side in Edge (the non-Chromium one) with zero dropped frames. Firefox grinds to a halt trying the same thing and only plays audio.
 
The better benchmark is the cpu benchmark.

1) use only Google Chrome
2) turn hardware accelerate off in settings (Chrome)
3) Play the 8k60fps video. Check if it set to 8k60fps.
4) your internet bandwidth has to be sufficient enough.

I know the 1950x has trouble doing this. I wonder if the 3900x and especially 3950x plays it smoothly.

seems to play no problem on laptop gpu, UHD620 probably has some acceleration, I am assuming when it says 4320p60 it is actually decoding that, as I only have a 1080p screen it is hard to be sure.

No, stutters a lot and CPU did not go past 1.56GHZ till I changed Windows Power Mode to Max to force 5GHZ but GPU (Titan Xp) took all the load so it is GPU based AFAICS.

This was in Chromium Edge Dev.
 
Ah my last one wasn't 8k, it actually has to show the 8k badge, you have to force quality to 8k, you can see what it is running turning on stats for nerds, still the intel GPU is doing all the heavy lifting. 10 dropped frames were when I tabbed out to bring up task manager.

If I disable hardware acceleration, it is a mess and the CPU dies on its arse.

Tried it on my 2920x CPU with GPU acceleration disabled, it looks like it can only manage 30fps as it is dropping most of the frames.

The 1080Ti handles it as well as the iGPU, ~80% load no dropped frames.

Did you used Chrome or Edge? Using the later got 60fps at 8k fullscreen. Using Chrome was a mess.
 
I used Firefox.

couple things: this test only works of your internet is fast enough, the video was be playing and not buffering to see accurate system load and also you need to make sure you set the quality to 8k 60fps or it may default to a lower resolution
 
It needs proper hardware acceleration either in the CPU or in the GPU. And an 8K monitor do display what you are streaming.
Have you got an 8K screen?
