The AMD RX 9070 is the objective winner of this comparison, securing victories in eight out of fourteen measured specifications. Its most significant technical advantage over the NVIDIA RTX 3090 is its memory clock speed, which is 107% higher. This superior clock frequency provides the primary edge for the AMD RX 9070, establishing it as the more capable component across the majority of the evaluated hardware metrics.

Users prioritizing memory performance should select the AMD RX 9070 for its substantial lead in clock speed. Conversely, the NVIDIA RTX 3090 remains the preferred choice for tasks that rely heavily on parallel processing, as it offers a 193% advantage in shader units. Choosing between these two components depends on whether your specific workload benefits more from the faster memory clock of the former or the significantly higher shader count of the latter.
