The NVIDIA RTX 3080 is the objective winner of this comparison, securing victory in eight out of thirteen measured categories. Its most significant technical advantage over the NVIDIA GTX 1070 is its FP16 performance, which is 29670% higher. This massive disparity in computational capability establishes the newer card as the superior option across the majority of the evaluated specifications, despite the older model maintaining a lead in specific memory-related metrics.

Users prioritizing raw computational power and modern performance should select the NVIDIA RTX 3080 to leverage its substantial FP16 advantage. Conversely, the NVIDIA GTX 1070 remains a viable choice for those who specifically require the 69% higher memory clock speed provided by that hardware. Your decision should depend on whether your workload demands the extreme processing gains of the newer architecture or the specific memory clock benefits offered by the older card.
