Specs of NVIDIA's Ampere successor codenamed Lovelace seem to be already available and all signs point to a monster of a GPU. Going by initial rumors, it seems that the AD102 GPU will have 2x the number of GPCs compared to Turing and a 71% higher CUDA core count compared to Ampere, which seemingly yields nearly 66 TFLOPs of FP32 horsepower.
