The NVIDIA RTX 3080 12 GB is the objective winner of this comparison, securing victory in eight out of thirteen measured specifications. Its most significant advantage over the NVIDIA GTX 1070 is its FP16 performance, which is 30540% higher. While the NVIDIA GTX 1070 maintains a notable lead in memory clock speed, outperforming the newer card by 69%, the overall hardware superiority of the NVIDIA RTX 3080 12 GB makes it the more capable component across the majority of technical categories.

Users prioritizing raw computational throughput and modern processing capabilities should select the NVIDIA RTX 3080 12 GB for its massive advantage in FP16 performance. Conversely, the NVIDIA GTX 1070 remains a viable choice for specific applications that rely heavily on the higher memory clock speed provided by that architecture. Choosing between these two components depends on whether your specific workload demands the superior memory frequency of the older card or the vastly higher processing power of the newer model.
