The NVIDIA RTX 4070 Ti SUPER is the objective winner of this comparison, securing victory in nine out of fourteen measured specifications. Its most significant advantage over the competition is its AV1 Encoding capability, which performs 100% better than the alternative. While the AMD RX 6900 XT remains a contender in specific areas, the superior encoding performance of the NVIDIA card establishes it as the more technically advanced option across the majority of the evaluated hardware metrics.

Users who prioritize advanced media processing and modern encoding workflows should select the NVIDIA RTX 4070 Ti SUPER to leverage its substantial lead in AV1 support. Conversely, the AMD RX 6900 XT is the appropriate choice for those who specifically require the 52% advantage in memory clock speed provided by its architecture. Your final decision should depend on whether your primary computing needs favor the encoding efficiency of the NVIDIA hardware or the memory clock performance of the AMD card.
