Understanding Video Encode and Decode GPU Support Matrix

Hi everybody, I was reading Video Encode and Decode GPU Support Matrix | NVIDIA Developer and I´m trying to understand what “Total # of NVENCS” means. Number of chips is not, maybe threads? 2 NVENC double the performance of 1 NVENC? but they have the same number of chips, just 1.

“# of CHIPS” indicate number of GPUs present on the board.
“Total # of NVENC” indicate total number of NVENC hw engines present on the board.

With multiple nvenc engines aggregate encode performance scales up when running multiple encode sessions in parallel. Refer NVENC Application Note - NVIDIA Docs for more details.

Thanks.
