At the GTC China 2019 Conference, Nvidia’s CEO Jensen Huang took to the stage to demo their upcoming chip. He has claimed that their upcoming RTX 2080 Max-Q GPU is more powerful than 9th generation consoles.
So while they are technically right as Nintendo Switch is the only 9th generation console out currently, it’s highly unlikely PS5 and Xbox Series X will be weaker. Xbox Series X, from what is said, will be around 12TF of GPU power where as PS5 will sit around 14TF. So it’s clear that these GPUs are way more powerful than the GTX 1080.
PlayStation 5 and Xbox Series X launches in Holiday 2020.
