Dear Professor:

I prepared a GPU workstation to perform AMBER calculations. A problem bothering me is that the cost of RTX30 series graphic cards are three times higher than their official releasing price at the present. And I noticed that Tesla k80 has reduced to an acceptable price for me.
I looked up informations for k80 and RTX3090 below: k80 contains 4992 CUDA cores, GPU Boosting frequency 875 MHz, 8.73 teraflops single-precision performance with NVIDIA GPU Boost; and 3090 contains 5248 FP32 CUDA cores, GPU Boosting frequency 1695 MHz, 35.7 teraflops single-precision performance.
My concerning is how much difference of AMBER performance between k80 and RTX3090 supporting? Which technical property is crucial for AMBER running speed and precision?
Thank you for your guiding.
Best Wishes
