Nvidia’s Integration Dreams

Re:Nvidia’s Integration Dreams by kiddico on Tuesday September 15, 2020 @06:39PM (#24487560)

I've heard everyone complain about drivers for amd, and (though I realize anecdotal evidence is no evidence at all) in my experience those people are full of crap.

I used the Fury(Fiji) and the VII(Vega 20) on linux and windows, and haven't expereinced any of the crazy shit people have claimed. Such as....

>(Navi's H264 encoder is still broken entirely as far as I know, it provides less than realtime encoding speed and extremely poor quality), so if you want to stream with AMD you have to use your CPU and crush your framerate

Where did you hear that? Not even slightly true. I used GPU encoding on both cards (@1080p, 60fps, 5500kbps, 1 second keyframe interval, 'quality' preset, full deblocking filters, and pre-pass turned off because I'm not insane) with zero issues. I would have liked to see more of an improvement in the VII's quality vs the Fury, but I wouldn't go as far as calling it non-functional.

I don't know who managed to get any of those to encode at less than realtime. I've done 1440 at 15500kbps to another machine for re-encoding and I can still play star citizen on High@60 fps with the same pc that's encoding.

And for the record, I also have a GTX 1660, 1080, and had a 770 before the Fury. I'm not fanboying, just relaying my experience.

Edit: Just to be clear, I'm not saying Navi is good to go. I'm refuting the general statement "if you want to stream with AMD you have to use your CPU and crush your framerate"

edit3 (lol): I 100% have no way to refute anything navi related. Looks like they completely changed the encoding engine in navi: https://en.wikipedia.org/wiki/Video_Coding_Engine#GPUs. Equally so, that chart incorrectly lists the VII as having version 4.0 instead of 4.1, so it may not be that trustworthy. I can't say until I have a Navi card to play with.

I had a 5770 and a 290x and both had periods (2013 for the 5770, 2018 for the 290x) of about a year where the latest drivers would randomly bsod on windows if you played a game on one monitor and watched a hardware accelerated video on the other.

It turns out anecdotes are different for everyone, that doesn't make them full of crap.

Indeed, wouldn't have included it if I didn't think the same.

I do however think making a blanket statement which has direct anecdotal evidence refuting it is pretty much bunk.

I don't know what kind of reply you're expecting. You've managed to use two AMD cards and not have driver crashes? Uh, good for you, but that doesn't mean the rest of us are "full of crap". I've also owned two AMD cards, and for both of them the drivers were flaky, on Linux and Windows. I'm sure they're not broken for everyone, but they were broken for me. Maybe if I bought another AMD card I'd get lucky this time around, but I'm not going to take the risk.

That was an intro to the second half of the comment which exclusively focuses on video encode capability. I Didn't directly refute that driver quality sucks. From the original:

"those people are full of crap" is a pretty direct insult. You shouldn't make that kind of accusation when you're not able to substantiate it or even willing to stand by it.
