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.

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.

nVidia managed to sabotage OpenCL leveraging nVidia's Vice President who is also the President of Khronos group, which is in charge of OpenCL.
He literally butchered the latest version of OpenCL in order to make CUDA the single greatest GPGPU API.
But all these are just malpractice and market manipulation very well known to be handled by the leather-jacket-man.
Regarding HW encoding SW, I could easily say that VCEEnc app for AMD cards is on par with NVEnc and QSVEnc for nVidia and Intel.
But I was referring to AV1 HW decoding here, which all of the modern GPUs support.
And Ampere's HW encoding is exactly the same like Turing.
They didn't change it.

NUC's are great except they are extremely overpriced. Quite often you can buy a laptop with the same configuration a lot cheaper than the NUC.

True. Still, NUCs are pretty well made, and offer 100% Intel hardware and drivers. Depending on the application this can be very preferable to a laptop. The integrated display, keyboard, mouse, and battery of a laptop can also be preferable in certain cases

Not only that, cheap laptops does not come with great io like this (especially Thunderbolt), and the sku:s with the higher end igpu.

Tbh were i live nuc have always offered rather good value tbh, i got a kaby lake one on release, I dont even think there were any laptops with hdmi 2.0 port at that point, which was pretty much a must for that machine.

Nuc is a nice concept, but ultimately a failed one, because they didn't push it hard enough. I'm surprised they even continue making these. The volumes are low and Intel isn't a motherboard/bios manufacturer...
