I did not deny that letting the RTX card do both is better

The encoding engine runs on different parts of the silicon, not with the Cuda, tensor nor RT cores. As long as your card doesnt hit the power limit, it shouldnt affect frame rates

Dear LTT community,

I was wondering if anyone has done, or seen, any side-by-side comparisons of recordings using an RTX card vs a GTX on OBS. I have both types of cards, and was wondering if I should use my GTX for encoding, or if I should switch my main gpu, and use the RTX for encoding.

Obviously the newer card will render games better, but if there's a massive difference in recording qualities, I may have to switch to better my streaming/recording quality.

 

I will post a similar question on the OBS forum, and if I find any results, I will update this post.

Thank you, LTT & LTT Community.

Ltt already did an encoder comparison though the resent cards. 
Newest is better. Like all of history.

So would you recommend switching cards to use the newest for encoding?

Or at least link me to that comparison so that I may decide for myself?

No difference from 1650 Super to Titan RTX, if that's what you're asking about

1070 VS 2070, I assume there'll be a big difference.

I would test this myself, but I since I'm missing a power cable, I just wanted some feedback from the LTT community.

Then you should ask "Pascal versus Turing", not GTX vs RTX because GTX can also be Turing.

 

In this case Turing is better, I've seen its results being comparable to x264 fast while Pascal is more like x264 veryfast

While this is accurate, couldn't one run games on a 2070 while simultaneously using the nvec encoder, without a massive drop in performance? So you only need the one card running?

Exactly. NVEC was built to be a one gpu solution, so if it works for you, then just run it as it is.

So until I get a red message on OBS, or frame drop, I won't change anything. Thanks @Jurrunio and @FakeNSA for your help.

I’d get the latest encoder you could assuming you only wonna use the gpu encoder for whatever you’re doing.
