AMD Polaris HEVC Encode/Decode, is this 'really' good for Streamers?

I have a question thats been bugging me for some months now, when i saw this article i was thinking, wow really? As the codec on current AMD cards are pretty bad for streaming, reading how Raja is claiming 4K streaming with Polaris, im kinda wondering how 'good' the quality will be?

So Raja said this a couple of months ago..

Raja Koduri, Senior Vice President and Chief Architect, Radeon Technologies Group

In summary, it’s fourth generation Graphics Core Next. HDMI 2.0. It supports all the new 4K displays and TVs coming out with just plug and play. It supports display core 4.3, the latest specification. It’s very exciting 4K support. We can do HAVC encode and decode at 4K on this chip. It’ll be great for game streaming at high resolution, which gamers absolutely love. It takes no cycles away from games. You can record gameplay and still have an awesome frame rate. It’ll be available in mid-2016.

HAVC? Must be a typo as it is HEVC. From what i've read, HEVC is H.265 that basically does the same quality as H.264 at half the bitrate.

I have seen Raja also make these claims in a video since that article, of which i cant seem to find the video now.

So Youtube supports H.265 already, and it will only be a matter of time when Twitch supports it too.

Anyway, does this mean the H.265 on Polaris is gona be as good (or better) as the H.264 on a CPU when it comes to streaming?

Does it support it though? I've tried uploading a H.265 video and it refused to accept it or render it.

I can't find anything online about YouTube supporting it, as they use the VP8 and VP9 codec for most of their content after you upload in H.264.

Although I do hope Polaris does deliver on it's encoding and rendering promises.

I read somebody on Reddit saying YT supports it but then i shouldn't really believe everything on there :)

I do keep hearing about VP9 though, so i guess we have to wait and see which comes out on top.

How good recording and streaming is will decide which camp I end up in with my next purchase. Really hope AMD has something as good as Nvidias shadowplay.

Yeah im hoping it'll be good (because current AMD quality is just not good enough for 3500kbps, which twitch non-partnered streamers are limited to) else its gona mean a CPU upgrade for me, even though my 2700K is fine for streaming at the moment.

VP9 is okay, but quality wise it can be all over the place. Although even a 4K video at 45Mb/s on YouTube is still worse quality than 1080p 15Mb on a computer sadly.

They really have to adopt it eventually as quality wise it matches it while using less bandwidth.

In regards, to AMD for streaming; I had a great experience with it in 2013-2014, although I was using FirePro D700's at the time.

I've already decided to go for AMD this year, and their dedicated hardware is one of the reasons. I just hope it's as good as they hype it up to be.

You can already stream using the h264 encoder on all gcn parts using certain software.

Not quite true as there are limitations to h.264 decoding abilities per each gcn.
H.264 is limited to 1080p on gcn 1.0/1.1
H.264 4k is supported by tonga/fury gcn 1.2.

H.265 is only supported by carrizo/fury at the moment but hdmi2.0 is only available with carrizo.

OP also compared to h.264 on a cpu, when it can already be done by gpu. But overall hardware encoded h.265 would be superior to both.

I compared to the CPU h.264 cuz the quality is just really bad on my 7950 at the same bitrate, i have to do something like 5000kbps on my GPU to get similar quality as my 2700K at 3500kbps.
 
This is very interesting.
Myself and a friend stream Dark souls 3 to each other. Would be nice to actual see the little details.
 
Damn, hardware encoding/decoding at 4k is serious bizness. I've seen maxwell nvenc based encodes at 1080 and they looked fine, great. With Polaris and Pascal, both NV and AMD are upping the ante pushing the res limit to 4k. This is great for everyone!
