Hardware transcoding quality

Driver issues can and will crop up regardless of the GPU you choose.

With regard to is the P2000 superior to QSYNC or Software. Software has the advantage if your media drops below 4Mbps, otherwise the P2000 and 9th Gen QS are equivalent in quality.

Since they added the toggle for disabling HW encoding, you can use it to get the best of both worlds if you have enough CPU, let the GPU decode and let the CPU encode.

All I want to know is if NVIDA HW transcoding is effected by this specific bug.

Can anyone confirm that with a Yes or No?

No (with 5 characters)

Ahh I see that you mention 9th Gen QS… I have been testing on both a 4th and then a 6th Gen Intel CPU so maybe that is why.
I bought an inexpensive P600 to test NVENC. I realize the 2 stream limit but this will let me see how it performs in this system. Then I can look into a P2000 possibly.

Edit… just tried on a work computer here with a 1050ti. NVENC seems to work great and I notice no blocks or anything when viewing transcoded HEVC to my iPhone over LTE. Pretty amazing actually. Wish I would have discovered this before getting the P600 - well it was only $70 so not that much out… however P2000 are fairly expensive going for 450+ CAD

Just for fun I patched driver on 1050ti and was able to run 5 simultaneous HEVC 1080p streams transcoded to 720p with no issues. I don’t expect the P600 to perform quite as good as 1050ti however. Makes me want to buy a P2000 now to fit in my Hyper-V system.

Just keep in mind it is the onboard RAM that governs how effective the card is with transcoding (# of transcodes) especially with HEVC 4K.

P600 arrived and I installed in my test system at home. Is pretty impressive and can transcode 5 streams no problem (I patched driver) and am sure can do more… these were a mix of 1080p x264 and x265 and transcoding to various eg. 720p, 1080p etc. and one on iPhone at SD 0.7Mbps. Impressive! It can do a 4K transcode but takes a while before the movie starts… probably due to the RAM limitation on card.
I am debating whether or not to move over my Plex Library on Hyper-V to this vs. buying a P2000 (I may just move library over anyways and duplicate it). I don’t really need that many transcodes and sort of want to move away from Hyper-V and my massive HP server at home.

Did you have to patch the driver? I was a little confused with the info about this, because it was mostly stated that the Quadro cards are free of the session limit.

Yes p600 has 2 encode limit restricted by Nvidia in driver. Only p2000 and higher models are normally unlimited.

Thanks for the info, so the information provided here seems to be correct then:

Yes I can only confirm what I have done on my P600 and 5 hardware streams no problem… that site claims I could do 7 1080p streams.

I may swap in the 1050ti from my other machine if I ever need more streams like that site claims eg. 14… which is closer to P2000 performance. Only benefit I see in getting P2000 now is support for Hyper-V - even 4K transcode on P2000 isn’t significantly better for the price offering only 1 stream more than a 1050ti. As time goes on and maybe patch stops working then the P2000 may be more realistic price to buy, but for now its too much $.
