RTX A5000/A6000 Simultaneous NVENC Sessions?

[j1144]

Hi,

I am looking to build a Threadripper Pro streaming recording workstation. Looking to ISO record 4 inputs from A7S III at 4K60P, a 1080p input from another computer, livestream, and record the livestream output.

How many simultaneous 4K60P NVENC H.265 encodes can the graphic cards handle?

I have been searching for weeks but haven’t found an adequate answer to build a system around.

Many thanks!

Hello @j1144 and welcome to the NVIDIA developer forums!

May I refer to another recent post where I answered a similar question?

Nvidia A2 and A10 video encoding performance benchmarks and performance recommendations?

Hi there! Are you aware of our Video Codec SDK? As part of the documentation you will find also an overview of raw encode performance compared across different GPU generations. Look for “NVENC Performance” on the NVENC Application Notes. Another bit of information is the GPU NVENC/NVDEC support matrix, where you can see that T4 and A2/A10 have the exact same number of NVENC chips (1) and capabilities, just different Chip generations. So other differences aside, you should still expect the same…

If I make a rough estimate regarding your requirements I think the A6000 might be hard-pressed to even manage 4 encode streams at 4k60. For that kind of throughput you will likely need a multi-GPU setup or dedicated Hardware.

Thanks!
