The AMD RX 6800 XT is the objective winner of this comparison, securing victories in ten out of fourteen measured categories. Its most significant technical advantage is its FP32 performance, which is 54% higher than that of the NVIDIA RTX 2080 Ti. This substantial lead in raw computational throughput establishes the AMD RX 6800 XT as the superior option for users prioritizing modern processing capabilities and overall hardware efficiency across the majority of evaluated specifications.

Users who require maximum raw processing power should choose the AMD RX 6800 XT for its clear lead in FP32 performance. Conversely, the NVIDIA RTX 2080 Ti remains a viable alternative for specific workloads that benefit from its 38% wider memory bus. Selecting between these two components depends on whether your primary technical requirement is the superior computational output of the AMD card or the memory bus advantage offered by the NVIDIA hardware.
