Using chrome with a 1070 hardware acceleration enabled.
Let me see you do this and game on a 4c8t CPU.

you have a picture of a 4 core doing it right above you, 10% cpu for that being streamed in 8k.
 
The difference being edge handles it better. The difference being I can use chrome to watch 4k/8k videos whilst gaming whilst a 4 core cannot.

so, the 4 core shown above only using 10% cpu power streaming an 8k video doesn't prove how little cpu power background tasks take.


lol...ok I'm done,- you win...off to buy an 18 core as apparently I need 8 cpu cores just to watch YouTube on a second screen LOL.....thanks for the laugh!

Yet you chose to ignore the person with a 4690k at 100% also.....
Selective reading and hearing.
 
Edge is using AVC, and Chrome is using VP9. VP9 is usually more cpu intensive on videos that can't be hardware decoded (quicksync only supports upto certain 4k profiles, off the top of my head).

@gavinh87, can you give the stat's window a screenshot after a full play through. Interested in dropped frames under AVC and VP9?
 
Not sure what they are doing to get such low utilisation on the Intel there. Mine is 60-70% at 8K with i7 4790K @ 4.36GHz

Edit: A standard HD video on YouTube utilises 10-12% utilisation.

Because hardware decoding kicks in on standard HD, hence low cpu as all it is doing is passing the data across. There are no hardware decoders for 8k yet afaik.

Will do this when I get chance.
 
Is B2 stepping likely to include improvements to the memory controller? I'm too scared to buy atm because I can't spend 3 weeks farting around with frequencies and latencies finding stability...

Who knows. It doesn't take that long to find stability, not now the bios is better anyway. Latency means little to ryzen right until you hit 3200 then it has a part to play.

Technically speaking for best stability you should wait till is end of life. Unless your in a hurry, wait a few more months, or even zen+.
