AMD's new 7nm zen2 based ryzen 4000 'renoir' laptop chips were announced today, they don't support AV1

Zen2 based...
Also AMD is always slow on HW codec, or instructions.

Is much more important on the next mobile SoC.

Zen 2 based doesn't require them to use any specific video decode block. They can release zen 2 chips with a newer video decode block that can decode av1.

Unlikely, the 'Renoir' 4000 series APU with Zen2 cores is likely to be the last major design with Zen2, with following low cost and embedded designs likely to be derivative.

It seems likely that the Zen3 based Cezanne APU (like 5000 series) will have AV1 decoding blocks, perhaps maybe the new discrete GPU's expected later this year too.

Media features are typically part of the GPU, not the CPU, as such Zen2 or Zen3 wouldn't make the key difference, but the Vega graphics on them would - which isn't even RDNA yet, so its rather old.

Renoir SoC has a special version of Vega at 7nm that has borrowed multimedia engine from Navi aka RDNA.

We have to actually run DXVAChecker to see real features and decoding speed.

OnePlus 8 Lite will support AV1 HW decode.

The normal or the PRO version doesn't because Qualcomm do not support it.

What is Qualcomms deal at this point?
Are they silently preparing another Patent Pool for AV1 like Sisvel, or are they just lazy and indecisive

new macbook air has been released, it uses a 10th gen intel processor, no info about AV1 decoding or not: https://www.apple.com/uk/macbook-air/specs/

10th gen Intel CPUs don't support HW accelerated anything in regard to AV1.

AV1 decode takes a lot of transistors, which are expensive. Are consumers willing to pay an extra $5-10 for a phone with AV1?

AV1 really didn't get anywhere near the kind of tweaking and tuning needed to make for efficient HW and SoC decoders like the MPEG codecs have. I'd expect AV2 to be a lot better in this regard. But VVC will provide better compression efficiency than AV1, with less of an incremental cost increase than AV1. Even if VVC costs $1 a unit in codec licensing, it likely would still be cheaper to a SoC vendor than AV1.

Plus Qualcomm spent all those resources on VP8/9 to never see it being used meaningfully outside of YouTube, and not providing any customer benefit beyond what H.264 already delivered.

Eh? Wasn't AMD and nVidia involved in AV1 development + several mobile SoC developers?

From that alone it would seem AV1 had more input from actual hardware vendors vs a theoretical hardware/transistor cost in MPEG development schemes as I've never heard of hardware vendors being involved previously.

Of course time itself was a significant constraint on AV1 development.

Honestly noone really expected wide-spread hardware deployment before middle/end of this year. That one SoC already has it and another doesn't seems perfectly normal to me. Adoption takes time, SoC development cycles take years. Something that is available today would've planned to include AV1 over a year ago.

People were also ranting that VP9 is even worse for hardware implementation
Lo and behold, Youtube started using it and every cheap chinese SOC managed to implement it

Still very much hoping for hardware decode.

This definitely can't be seen as anything other than a major blow towards AV1 adoption. If the latest Qualcomm SoC doesn't support it, why should anyone else care? :|

Maybe next gen? But I mean.. The bitstream spec has been out for years. I know there was an eratta that kind of reset the clock not that long ago but.... yikes.

If I was all-in on AV1 I'd be very nervous right about now. HEVC is delivering great results today, and LC-EVC and VVC both look quite promising in the near future, and hardware support is completely guaranteed for VVC.

just wait for nvidia this year.

and microsoft has to do there part too.

it took 19 month to get VP9 hardware decoding on maxwell the decoder was just not accessible just to show how this worked and there was no word about it too the card where just able to do that from one driver to another and the windows update 19 month after it release date...

BTW that 3 years after VP9 was released.

i don't see a reason to get nervous.
in the end it doesn't matter if youtube and/or what ever are forcing this type of content the hardware decoder will follow.

Intels upcoming Xe architecture presumably supports 12 Bit AV1 according to a new leak: https://videocardz.com/newz/exclusiv...-0-xe-graphics




RKl-S will use the smaller GT1 from Intels Gen12LP.

Now THAT is some good news (Intel). Even if it's decode only.
