Which is better, Pascal or Turing Nvidia NVENC for streaming at OBS

[PCForStreaming]

From doing research we know now that NVIDIA gpu produce better performance for streaming now. For a start I was wondering how GTX 1070 or 10xx series (pascal) compared to 16xx series (turing) like 1650super/1660.From looking at benchmark it is clear that 1070 can gives much better FPS in games compared to 1650 for example because of course they are 2 items of a very different price, 1070 is way more expensive.

 

But look at this video, he tested and said that his GTX1080 perform worst in streaming compared to 1650super. It absolutely producing worse. He siad he can only stream up to 900p60 with GTX1080 compared to 1080p60 using 1650super. Looks like the game dropped a lot of FPS if he do streaming with his GTX1080. Please continue reading my post, I include the video link down below.

 

From this I heard that 1080 produce worst when streaming compared to 1650 because 16xx series and in this case 1650 has a dedicated chip to encode streaming and 1080 don't eventhough both have NVENC. This chip allow 16xx series to save their VRAM for the game instead of having some of them taken for encoding the stream which happen on the 1080 because it doesn't have the dedicated stream encoding chip.

 

So I am asking for anyone who have streaming experience with both cards 1070/1080 vs 1650super /1660 or 10xx series vs 16xx series. Is it true that even 1650 super will perform better in streaming compared to 1070/1080?

Turing is better for streaming that has been proven however the 1070 will provide more fps maybe going for the 1660 super might be the best overall.

I don't own any of these GPU but the answer is no. FPS drop is not significant when you record/stream with NVENC, at least on the streamer side. 

 

Also he said 1080 don't have dedicated encoder chip which is wrong.

Thank you, I was wondering as well because isn't that NVENC in the first place is a technology for encoding with dedicated chip on the GPU. GTX 1070 and 1080 have NVENC so they got to have the chip as well embedded inside them.

But still like it's just so confusing because I can not find any video that prove streaming with 1070 or 1080 is a smooth sail. They are just showing benchmark of games. But not while streaming or comparing the streaming results compared to 16xx series like GTX1660super

It has a hardware encoder that works separately 

Both Turing and Pascal 

Which one has better quality ? 

The new nvec on Turing is by far better 

Even exceeding x264's quality.

Turing all the way.

 

With pascal there were some quality issues such that x264 looked a little better (IMO) even though it would have a lesser performance hit overall (compared to x264).

 

Turing is the best of both worlds.  I get almost no performance drop, and its very hard to tell the difference between a x264 medium and Turing (at least I cant tell).  Main difference is my CPU gets to spend all its energy pushing frames.

Thank you, this been really helping me to push my choice leaning towards GTX16xx more.
Is this also including GTX1650super which is using Volta NVENC, how 1650super compared to 1660 in terms of the streaming results?

And also with better quality is it means smooth movement on the image?? Because I notice in some video on the Youtube of like stream clips compilation of a game let's say Valorant. Some clips do have significant smoother image movement. It's like it is moving in better FPS.

If in my end I can only see up to 60FPS at most why I can notice that some of this clips look like have far more smoother/higher FPS?

No 

Only the 1650 non super uses the old volta encoder

Can you give me an article, webpage, or video that is saying this?
I cannot find this on NVIDIA  encode decode GPU support matrix
https://developer.nvidia.com/video-encode-decode-gpu-support-matrix

It only listed 1065 as Volta NVENC

The 1650 super 

Uses the new nvec. 

The 1650 (non super ) has the old volta encoder.

The GTX 1650 Super however uses the Turing NVENC engine as it is based on the TU116 rather than the TU117 used in the regular GTX 1650.
