What os are you using?

It seems like the gtx/rtx line doesn’t have the same issues that quadros do.

Its Windows 10 Professional build 1809. The GTX 1660 is the new Nvidia workhorse they have been pushing. Did you look at the Nvidia encode/decode matrix for your card? The reason I wen't with this particular one is it supports all varieties of encoding and decoding.

I am super familiar with the 1660. I don’t have issues with my 1080ti. There seems to be some issue with quadro p2000s though in Windows. Which I have in my server.

The p2000 handles everything that is out right now. But I’m aware the newer cards support more new features, and they are faster.

It could be just the increase in RAM and Cuda cores my card has over the P2000. Before the last couple betas i was only getting about 20 FPS when transcoding 10 bit media. Since then there have been 2 beta updates and and Nvidia driver update. Could be a combination of both that increased the transcoding.

The emby betas have helped and I saw an improvement with the newest quadro driver so both for sure.

And cuda cores and ram won’t matter. Ram would help if you’re doing many streams but I was doing one.

The card really only uses its nvenc nvdnc engine chip to do transcoding. The chip that’s in Turing cards is vastly improved.

Yes, I have seen a much better improvement from the Turing cards. Prior to the 1660 I was running a GTX 1050 and it was only doing half the FPS that I am seeing with the 1660 now. Both were 6GB cards, just different chip.

I just did some testing with 8bit and 10bit transcoding. The results I am seeing are below. 

 

8bit transcode using H.264 NVENC/DEC

 

270-280 FPS

GPU decode is 100% used

GPU encode is 45% used

 

10bit transcode using H.264 NVENC/DEC

 

56-78 FPS

GPU decode is 16-20% used

GPU encode is 17% used

 

Seems that 10bit transcoding has increased 2-3x in FPS. The GPU usage seems to correlate with that increase in FPS. But, it still seems that 10bit isn't fully utilizing the GPU to its potential. I am running the latest Nvidia driver (425.31 released 4/11/19) with a GTX 1660 6GB.

I posted similar results on the 4th, so I am glad to see I am not the only one having issues.

10 bit h264 or h265? 264 10 bit isn’t common.

I also see these results with a Turing 1660 card.
