Why no hardware acceleration on RX480 !? (4K@60 Youtube in Chrome)

[BrightShadowDK]

when i watch 4K@60 Youtube my CPU peaks at 100% and the GPU uses only 13-15%
(on my 1050ti it's the other way around: it plays Youtube in 8K with a dual core G4560)

System:
i5-6600

RX480 4GB (got the same problem on 2x RX470's)
16GB
Win10 Pro (ver. 2004)
Google Chrome + ABP + Gallerify

Did "DDU" and installed RADEON Software/Driver, and tried to disable and reactivate Hardware Acc. in Chrome..
(can't get it to work ever on any system with a RADEON GPU.. on NVIDIA it works Plug and Play..)

If I'm not mistaken, Polaris (which the RX 480 is based on) doesn't support VP9 decoding which is what YouTube uses, only Vega and Navi GPUs do from AMD's lineup.

This sounds insane.. a 1060 grade GPU that can't decode Youtube !? WTF.. can anyone else confirm this ???

Ok.. the RX cards are dead to me  my pc is mainly HTPC: so now i extracted the nice "Sapphire RX480 4GB Nitro Plus" and swapped in an older "Gigabyte Windforce GTX 960 4GB" and now the pc decodes 4K Youtube using 30-60% of the GPU and 20-32% of the CPU..

so now i got most of my CPU resources back to do other tasks  
(but im properly gona invest in a RTX 3050-3060...)

The RX 480 was a gaming focussed card, not a multimedia card. It was also extremely low priced for a good gaming card. (partly due to the lack of hardware decoder/encoder development)

I was following the GTX 10-series and the RX series intense when the launched and both was marked as gaming cards but i never heard this..

so what functions do ryzen cpu's don't allow? NO Netflix or facebook

BTW.. you write "RX480 was.." like it was 20 years ago  it's only just been 4 years..

The GTX was a multimedia card as well as gaming, and it was priced higher across the board due to it.

 

Ryzens don't have restricted functions in the sense you imply.

 

4 years and 3 (almost 4) GPU architectures ago. Polaris was heavily criticized for its lack of multimedia features, which is why later cards had more refined multimedia functionality. AMD learned and changed, don't hate on them just because you got a card from before they learned.
