The AMD RX 6800 is the objective winner of this comparison, securing victories in ten out of fourteen measured specifications. Its most significant advantage over the NVIDIA RTX 2070 SUPER is its VRAM capacity, which is 100% higher. This substantial increase in memory provides a clear technical lead for the AMD RX 6800, establishing it as the superior hardware option based on the provided data points.

Users prioritizing maximum memory capacity should choose the AMD RX 6800 to leverage its doubled VRAM advantage. Conversely, the NVIDIA RTX 2070 SUPER is the better selection for those who prioritize power efficiency, as it maintains a 14% advantage in TDP. Selecting between these two components depends entirely on whether your specific build requirements favor the increased memory headroom of the AMD card or the lower power draw of the NVIDIA alternative.
