As per my search,the below is the compatible one for R-820 DELL servers.

75W NVIDIA Quadro 2000GPUs

Except this,any other CPU cards like mentioned below is compatible to R 820 ? If its not compatible,could you help me to get the DELL R820 compatible cards from Intel/NVIDIA ?

 

GeForce RTX 2080 Graphics Card | NVIDIA 

 

Thanks,
