Does the videocard affect the performance of Nvenc

[Optimal]

I was wondering if a higher quality videocard would affect how good your encoding is. And is it he gpu doing the encoding or a seprate chip on the card.

 

As an example, would a 2080ti give you better or equal performance to something like a 2060 and if the performance of the gpu effect the performance:

How much difference really is it beetween something like a 1660 and a RTX 2080ti while streaming in 1080p60fps for example?

I think it was either this video or another EposVox OBS video where he shows a chart with all the GTX/RTX cards with what NVENC hardware they have. 

 

 

IIRC, the 2080 down to 2060 all have the same NVENC chip.

The quality of the encode should not change based on the card, so long as we're talking cards that have the same encoder. The RTX 2060 and the RTX 2080 Ti should give the same quality assuming the same resolution, bitrate and content.

What may change is the hit in performance when using NVENC. The RTX 2060, depending on the game or content of course, may suffer more of a performance hit than the RTX 2080 Ti in the same content, but that's kind of a given because the 2060 is a weaker card.

It probably matters for how long it takes to render a video, i'm not sure but I doubt it has any effect on streaming, and the quality will be the same ofc (talking about cards that have a different amount of NVENC chips, or different generation)

 

Also, as you can see 1660 up to 2080 Ti all have the same number of NVENC chips

I've noticed that with my 780, I get slightly lower game performance when encoding on it.

 

But I don't know if NVENC is different on Kepler cards than Pascal or Turing(I know the latter both have better encoders).

I don't have an Nvidia card, but using Radeon ReLive does hit my performance a little bit on all of the cards I've owned, on my 7850, 580 and Fury X... even in TF2, apparently.

Basically, from what I've gathered, GPU encoding will hit your GPU a bit (well duh) but saves massively on CPU performance. Good enough of a trade-off if I say so myself.

That makes sense. Your stream can also suffer if your game is optimized to use all your cores.

Thanks for showing me this video I didnt find any «spec» related videos/posts so thats why i commented.

And thanks to everyone else for the amezingly quick response.
