Currently I have i7 4770k CPU and I am using quicksync for streaming since some games like Archeage which I play now is very CPU hungry (up to 70% load for all cores for game only at 4.1Ghz overclocked CPU) Here on forum I found that HD5000 series may be better for encoding because of improved decoder/encoder at higher GPU series. Does anyone here have experience with streaming on HD5000 series? Is there really better picture at same bitrate? Currently HD5200 is only available at intel NUC form factor, but it could be good as dedicated stream server in pair with Avermedia Extremecap u3.

Re: Quality difference for Quicksync on HD4600 vs HD5000/520
zetmor .... hes got an i7 4770k at 4,1 ghz thats a quad core with ht so 8 threads this thing is powerful enough and is the top of the line cpu the next upgrade would be an 4930k which would be a 6 core with ht (12 threads) but also fucking 500 bucks.
quicksync on haswell cpu's is already pretty damn good its not as good as cpu encoding right now obviously but the result shouldnt be that bad imo

Re: Quality difference for Quicksync on HD4600 vs HD5000/520
In most cases slightly overclocked 3-4 th generation i7 CPU can handle 1080p@30 and veryfast preset. Quality difference comparing to QuickSync is noticeable. With 6 core CPU you can go "faster" preset and maybe "fast" but I doubt that. Quicksync is not that bad comparing to other hardware solutions: Aver capture card with builtin encoder and Nvidia with its Shadowplay.
I have tried Avermedia card, and to my mind there are 3 main problems:
-Aver hardware encoder provides very bad picture quality - for high motion scenes you need to set higher bitrate.
-Poor software support - Aver Recentral software for streaming is a crap comparing to obs/xsplit and is not an option comparing to them. Aver hardware encoder is supported by X-split only in addition to Recentral.
-You need to purchase extra hardware and software which you can use only for streaming (a good CPU will help you in many other things)
My thoughts:
Card is only good to use as a video source. Sometimes "game capture" or window capture is working bad depending on game and capture card works always. Aver Card with encoder + Xpslit costs 200usd+ and to my mind its much better to waste this money for fast i7 CPU and use it together with OBS - you will have much better results. Also there are cheaper capture cards available w/o hardware encoder.
Nvidia announced they will add streaming support right in time, I found this info the moment I was thinking what to get HD7970 or GTX680/780 card, after their promices to add support for streaming i went green side. Too bad they had numerous delays with streaming software support release, but at least they did it recently. The problems are same as with Aver:
-NVENC hardware encoder provides bad picture quality - sometimes I doubt it is really 1080p there, seems to be some downscale. Overall the quality maybe slightly better than Aver, but still worse than QuickSync.
-Poor software support - Only Geforce Experience is able to use this encoder.
My thoughts:
Overall its better than Aver card because you dont need to buy extra hardware, you will need to stick to "green side" but as their GPUs are good, its ok for this moment. I understand its still beta, but if they really want their encoder to become popular, they need to release a devkit so other software developer could use it too. At current situation, this program is useless, its missing many capture modes, required features and options. It is definitely FRAPS and all its clones killer, but its not a streaming software now.
*UPDATE* OBS can use it too!!! ver 0.60 build9 but the quality is still so so :(
As for GT3 GT3e (aka HD5000 HD5200 series) Intel says they have improved encoder even futher making it able to work with 4K video. This means encoder could be up to 4x more powerful (http://en.wikipedia.org/wiki/4K_resolution) than at top current gen (HD4600) As even now HD4600 quality is good, next encoder gen can be all we need to have good quality stream without extra system load. Software support for quicksync is OK. Too bad currently there are no desktop CPU with GT3e available, and the first will appear only at the end of this year. Also, at the end if this year Haswell-E will come to market, with 8 core CPU for ~600usd and it will allow to stream 1080p@30 with "fast" preset with no doubt. But if GT3e encoder perfomance will be improved, there is not much sense to purchase another 8 core monster... I would go 4930K but I know that 8 core will be available for same money at they end of the year and this stops me :)
