Which one has more power and why? As far as I know only the PS5 runs on RDNA 2.0?
Although the RX-5000 models are RDNA-1 GPUs, the RX-6000 graphics cards are also based on RDNA 2. In addition, the XBox Series X also has an RDNA-2 GPU, even a slightly larger than that of the PS5 as far as I know.
In terms of performance, the RX 5600 should be similar to the consoles, but these could effectively perform better due to better optimization of the games. In addition, the RX 5600 does not have any ray tracing hardware.
