From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've wanted to buy an upgrade to my RX580 for years now, but I'd really like AV1 encoding support. With OBS finally supporting AV1 on all platforms (?), this actually makes sense. But I'm once again reminded how bad the used market for GPUs is in my country atm, so I'll wait for a while longer.
Now we just have to wait until platforms like Twitch support the codec too. It’ll be a huge leap, when they do
YouTube already has it, wouldnt hold my breath for twitch. they still havent had h265 support, and its not like thats brand new or amything.
Isn't that due to that codec requiring royalties? Half the reason there is such a bit push towards av1 instead of h265 is that there is no royalties involved
That's because H.265 is patent encumbered. Firefox doesn't support H.265 at all and Chrome only supports it if the hardware does. In order to support accepting H.265 input from streamers, Twitch would basically have to pony up the compute resources for full-res realtime transcoding for every H.265 stream to H.264 -- either that or put up with a lot of bad press surrounding people not being able to stream at full res anymore.
AV1 would introduce a similar hardware requirement because not everyone even has AV1 Decode, and even fewer have AV1 encode. AV1 encode would only be available on people on gpus using the latest generation, blocking anyone buying previous generation stuff (so no AMD 6000 or older, or Nvidia 3000 or older, and non Intel Arc products).
All (recent) major browsers I'm aware of have software AV1 decode as standard, so the receiving end wouldn't be a problem apart from higher CPU usage. As for encode, obviously this wouldn't be universal -- just streamers who had the computing power (hardware or software) for realtime AV1 encode would be able to take advantage of that on Twitch.
the browsers have the software, but not the hardware decode step.
software decode, especially for mobile, would be battery draining and no streaming service would realistically would use it without the userbase having hardware decode support.
for pcs, av1 hardware decode is amd 6000 or newer, amd phoenix apus, nvidia 3000 or newer gpus, 11th Gen intel cpus or newer.
for mobile, its only like a small portion of the phones released in the past year and a half or so.
for iphone, the list is the iphone 15 pro max. and for the other devices, things using the M3.
as long as the world is a mobile first mindset, theres no way theyre going to ask evwryone on mobile to take a significant battery loss just for a higher resolution stream.
Isn't h265 proprietary? Maybe they just didn't want to pay license fees
Got a 6700XT second hand about a year ago when the price finally came down from astronomical ridiculous crypto bubble crazy, to almost reasonable. Just looked and they're still going for the same price. Thought this would have dropped a bit by now, but I guess not.
Yes, I've also had an eye on the 6700XT, but I made the bad decision to wait for the new gen and hopefully a price drop for older GPUs. The stable used prices are probably because of people who bought at exorbitant prices who don't want to sell their GPU for nothing, combined with the new gen having the same price to performance ratio.
Now with the 7600XT having 16GB VRAM, I've thought about buying until I noticed it only supports PCIe 4.0 x8, which is half the bandwidth on my PCIe 3.0 x16 slot. It's a B350 board I want to upgrade to a 5800X3D and use for years to come. This means I'm basically forced to either go with a 7700XT, or go with an older 6700XT.
Anyway, waiting years for a new gen isn't an option either, so I'll stay frustrated for a while longer.
Fun coincidence, 16 lanes was one of my concerns as well when I got mine. I'm also on an old AM4 motherboard. Currently have a 3900X CPU which is plenty for my needs for now, but it's good knowing I still have an upgrade path to an X3D. AM4 has been an awesome platform in terms of upgradability :)
