Let me be clear: the same settings for conversion with h265 nvenc, 2 different video cards ... 3070 or 3080 ... will one perform faster than the other? I know that in nvenc, the card doesn't really matter ... or am I wrong?
It varies depending on generation of hardware. Quality and filesize will also be worse on older generations of hardware.
Within a generation of cards, performance will mostly be the same. 3070 -> 3080 as your example
A quick terminology correction:
x265 is a software implementation of hevc, sometimes referred to as H.265
nvenc (h.265) is a hardware implementation of hevc
To be clear, Nvidia cards do not accelerate x265
You don't get any of the quality or file size benefits that x265 has over NVEnc
one more question: in h265 nvenc, does the speed it works with matter, low vs default?
is it the same thing as when we use the processor or the conversion with nvenc, is it special ??
The nvenc presets in their current iteration are a bit "broken". They have a new preset system we'll be implementing later this year all going well which is hopefully a bit more like what x264/5 does.
However, "Slow" presets will typically be a bit slower.
3060 is fine for encoding only. I wouldn't be surprised if that card is bottlenecked by the decoding done on the CPU so don't be surprised if it doesn't run at full speed. Even my 1060 (in most circumstances, doesn't, peaking around 80% in the best case.). For full speed, you'd need to move away from HandBrake to something's an NVEnc only pipeline.
It's fine anyway, I can't wait for the new nvenc x265 presets
I asked, because at one point, I was surprised to see how a 1060 on x265 nvenc, runs with the same number of fps as a 2080TI
if you don't play games and just video editing and conversion, why spend so much money on an expensive video card when you can do the same with a cheaper one, right?

Maybe you can answer this question for me, thank you
have you made any changes regarding x265 nvenc? on slow it seems to go with more fps / s to the video cover and you changed the default to 22, where it doesn't make such a big file anymore?
Is that what you were referring to in an answer given above?
please answer me
Maybe it was a mistake, I had to say H265 (nvidia nvenc)
There are some changes, because, at slow speed, my video card processes somewhere at avg 130 fps.
Now it has increased to 400, the same settings ...
