How many concurrent streams can Quadro RTX4000 transcode (e.g. 1080p, 30FPS, H264)?

Hi,

(https://developer.nvidia.com/video-encode-decode-gpu-support-matrix ) indicates that unlimited NVENC sessions are possible on Quadro RTX4000. However, for any practical use, one should know the possible throughput (of course, under certain known conditions) that can be achieved even before we buy. We couldn’t find enough data on the performance. For example, if someone could point out to performance/related information it will be helpful. For example, how many parallel streams can be transcoded (or any similar type of video streaming application) for streams of 1080p, 30FPS, H264, Basic Profile can be considered as one such use case. As long as we know how many concurrent encoding sessions are possible in any kind of application, even that is ok to get some idea. The Whitepapers and other technical notes from NVIDIA doesn’t seem to provide this. Any help in this regard will be appreciated.

Thanks!

Completely outside my area of expertise, but this table provided by a 3rd party seems to indicate 27 streams (of a particular kind) for the Quadro RT 4000:

I don’t see a detailed explanation of how the table entries were determined and what system configuration was assumed, so I would take this data as nothing more than an order-of-magnitude guesstimate.

NVIDIA offers some performance data for the Tesla T4, which you may want to extrapolate to the Quadro RTX 4000:
