Intel has launched Tiger Lake CPUs.
Intel and NVidia down. AMD to go.

And everything supported 10-bit decode that I know of, so we may finally have a codec that can be 10-bit always (although SW decoders are still somewhat slower with 10-bit).

Didn't Samsung throw their hat in with AV1 awhile ago now?

They usually announce their next Exynos flagship SoC around the end of the year, so we might see some action with them too.

The COVID business slowdown seems to have impacted the production timeline of Rockchip RK3588 and perhaps the Amlogic S908X which also have AV1, but I think that there are at least weaker S905X4 chips in the wild with AV1 capabilities too.

I'm still holding out hope that the newly awaited "Sabrina" Android TV dongle from Google will use S905X4, despite early claims it uses the older S905X2.

Pretty sure it uses the S905Y2 which doesn't even have ethernet.

Qualcomm really is the elephant in the room... without hardware decode on popular Android devices AV1 will be a tough sell for OTT service operators I think.

An interesting slide from nVidia.

Using latest Chrome M85 and YouTube 8K HDR 60fps AV1 content, a Core i9 9900K managed to decode in SW only 28fps with a 85% CPU utilization whereas an Ampere AV1 HW decoder manages real-time performance of 60fps without bothering CPU at only 4% utilization.

The only thing missing is the HW decoder's utilization during the achievement.

No surprises there. 8kp60 AV1 decode is absolutely punishing, especially considering the mention of HDR which means 10 bit...

It's extremely impressive that the new RTX 30 series will handle it in hardware!

This is why a hardware decoder is so important for mobile devices with limited power, thermal headroom and fewer cores.

And for premium content licensed with HW DRM requirements. AV1 would be useful for YouTube and Twitch way before premium services. Particularly as most premium playback devices already have HEVC, but YouTube and Twitch are mainly watched in browsers, which are mainly Chrome and Firefox, and only have H.264 as a baseline.

Chrome and Firefox have had AV1 decode for nearly 2 years now, sheesh.

Not with studio-grade DRM. And with SW decode and the performance/power challenges thereof.

Hello,

Just a very quick message to let you know that I finally could have an answer from a AOMedia founding member company, and I thank them very much for their time, and so no surprise, they confirmed me that NHW is not of consideration/interest for AOMedia.NHW could have been a tool for AV1/AV2, but the tools quality is evaluated with PSNR and SSIM curves, and NHW has very too bad PSNR and SSIM results -but again despite this, I still find that it is visually more pleasant because it has more neatness...-.

So NHW will definitely stay a hobby (will have to slow down my work on it in the next months), but if you found time to take a look at NHW and if you would have advice/suggestion about it, do not hesitate to post it on the NHW thread, or send me an email.

Cheers,
Raphael

https://github.com/xiph/rav1e/releases/tag/v0.4.0-alpha
- This is a new big release of rav1e after 7 months making the encoder sensibly faster and better.

AV1-decoding with RTX 3080 compared to GTX 1080 and RTX 2070: https://youtu.be/lTRbLnWdqwk

How smart to compare HW decoding of AV1 using 3080 to CPU AV1 decoding using 1080 and 2070 Super which the video subtitles say it's a 2080 card.
And HW AV1 decoding is not using NVENC that this incompetent guy thinks.
It's using NVDEC.
The NVENC part (HW encoding) of Ampere cards is identical to Turing cards.
The only thing useful of this generally useless clip is that YouTube's AV1 8K60fps clips utilize about 47% to 54% of AV1 HW decoder of Ampere card which I think is impressive and a metric for AV1 HW decoder of Tigerlake Xe GPU and AMD RX 6000 series to beat.

Benchmark seems legit even if they don't know the lingo. Damn, the 3080 is one hot, power-hungry card. Hopefully it'll be optimized in drivers eventually.

No need to buy 3080, I'm sure they are going to release 3060 and possibly 3050 card.
And there is also Xe from Intel.
Personally, I'm going to wait for a budget RDNA2 card hoping for at least 4K 10bit AV1 acceleration or even better (like 8K60fps)

I'm a bit curious to what you are referring to?

From what I've seen, yes the power draw is high under load, but efficiency is rather good for an top of the line card, although its not that impressive for an die shrink generation, and both stock cooler and third party seems to keep it under 80 degrees at rather low noise levels.

It's a bit of a shame that CUDA for GPGPU and Nvenc is so superior (at least at an software support level), havnt been able to consider an AMD card for years.
