Not only that, but there is roughly a 20% advantage in multiple specs in favor of PS5 or Series X, not just a 20% advantage in one direction. PS5's maximum GPU clock speed would give it roughly a 20% advantage in fill rate, geometry set up, culling, and other tasks. And when you look at the memory set up, Series X has about a 20% advantage in it's fastest memory and a 20% disadvantage in it's slowest. There isn't a single number that can define the capabilities of these GPUs, and these advantages and disadvantages can be leveraged or avoided to give quality results with proper optimization.
