You can take a look here for a detailed comparison of many Nvidia GPUs in terms of GPU encoding power and speed.

Is there a AMD GPU equivalent to CUDA to use this speed improvement on AMD cards too?

@Kleinrotti Seems the high core count works pretty good with AVX2 code.
Maybe it would be nice to have a checkbox in the future, to use AVX2 or CUDA. To prevent a bottleneck for high core count CPUS.

This is pretty normal when using 10 Bit instead of 8 Bit. Encoding takes a lot longer then.
-
Everything is fine, only H264 QSV is supported by this CPU/IGPU.

That's really strange, some days ago i compiled Voukoder myself and I had this issue too. But after a re compile this issue was gone.
Maybe you could try this Voukoder Version. It's compiled with ffmpeg 4.3 and Nvenc SDK 10. This Version works for me without this issue (Ignore the Rav1e Codec).
Just replace this dll with the same one in C:\Program Files\Voukoder.

As you can see in the logfile, the vEncoding, aEncoding and vProcess times are fine (this is what Voukoder is processing). But there are very high spikes at vRender times, that's what Adobe needs to send the frame to Voukoder.
In this case Adobe needs 1,18 seconds to send the frame to Voukoder. This could be caused by effects, color corrections or other applied things in Premiere.

Maybe you are using the broken Voukoder 6 Version where nvenc is bugged on some systems.
You could try this pre release version of Voukoder.

You can click on the small "+" symbol next to the descriptions "standard", "rate control" ... . The available options will be shown then.

Sorry, only the GT 1030 does not support NVENC encoding, the GT 710 supports H264 YUV 4:2:0 encoding.
Maybe you are using the broken Voukoder 6 Version.
You could try this release candidate version: Download

These cards do not support Nvenc encoding. Take a look here.
-
Maybe some old saved profiles of Voukoder cause this? Can you try to delete all saved profiles in Premiere/Media Encoder?

Increase the bitrate or decrease the crf/qp to improve the quality.
-
AMD GPUs currently don't support 10 Bit hardware encoding. The current models only support 10 bit decoding.

Ah ok I understand, you are using the COM interface to avoid licensing conflicts because of the closed source part of the Voukoder Connectors. This way the library is not used directly as shared or static library and does not conflict with licensing. So we need something like COM on Windows on MAC or linux too.
-
Would it be possible to use Voukoder as a shared library instead of using COM? This way it could be used with mac or linux, or I'm wrong?
-
If you want detailed performance comparison of hardware transcoding (NVENC) just look here. But keep in mind that this data cheat does not compare performance of one encoding, its comparing how much encodes the GPUs can run simultaneously.
If you only encode one source, the encoding speed between a 2080 and 1660 is pretty much the same.
-
As far as I can see in the log file it has nothing to do with NVENC I would say, because the vEncoding times are fine.
Whats very high are the vRender times. That's the time Adobe needs to render the frame and send it to Voukoder (NVENC). Something in your Project will cause this I think.
