Whether a card is better strongly depends on used applications. CUDA oder Tensor core softwares benefit very much from Nvidia cards. (It may be that you do not use such so AMD cards are an option, if also drivers are stable for your use case.)
The Nvidia GeForce RTX 4070 Super retails for the same original price of US$599 as the RTX 4070 while offering nearly 21% higher shader counts. We evaluate how this benefits synthetic benchmarks and games in comparison with other cards, particularly against Team Red's offerings such as the Radeon RX 7800 XT that retails for US$100 less.
