Maximum FPS of decoder

I tested RTX 3090 decoder performance and got 1600 FPS for 1280x720 h264 video and 800 FPS for 1920x1080 h264 video. According this matrix, the RTX 3090 is 5th Gen of NDEC Generation and it has single NDEC chip.

GeForce RTX 4090 has the same decoding setup. Does that mean it also has the same decoding performance as the RTX 3090?

And what about NVIDIA A100 Ampere having 4th Gen having of NDEC Generation and 5x NDEC chips? Is it possible to find somewhere how many FPS it has?


RTX 4090 has similiar hardware decoder performance with RTX 3090.

A100 decoding performance is in Video Code SDK | NVIDIA Developer. It can support 83 x 1080p@30fps streams decoding simultaneously.
