The NVIDIA RTX 3090 is the objective winner of this comparison, securing victory in nine out of thirteen measured categories. Its most significant technical advantage is its FP32 performance, which is 510% better than that of the AMD RX 480. While the latter component remains competitive in specific areas, the former demonstrates a clear lead in raw computational capability across the majority of the evaluated specifications.

Users prioritizing maximum computational power should select the NVIDIA RTX 3090 to leverage its substantial lead in FP32 performance. Conversely, the AMD RX 480 is the appropriate choice for budget-conscious buyers, as it maintains an 87% advantage in MSRP. Choosing between these two components depends entirely on whether the user requires the superior processing throughput of the newer hardware or the cost efficiency offered by the older model.
