The AMD RX 9060 is the objective winner of this comparison, securing victories in eight out of fourteen total specifications. Its most significant advantage over the NVIDIA RTX 3090 is its AV1 Encoding capability, which performs 100% better. While the competition holds a substantial lead in other areas, the superior encoding efficiency of the AMD RX 9060 makes it the more versatile option for users prioritizing modern media processing and streaming workflows.

Choose the AMD RX 9060 if your primary focus is on AV1 Encoding performance for content creation and media tasks. Conversely, select the NVIDIA RTX 3090 if your workload relies heavily on raw processing power, as it offers a 486% advantage in Shader Units. This massive disparity in shader count makes the NVIDIA RTX 3090 the clear choice for users whose applications demand high-density parallel computing resources rather than specialized encoding features.
