I have always preached that uniform hardware is a significant advantage for consoles, but there are those on here who will not admit this is true at all to any extent.
It's a basic misunderstanding.
It is much easier to optimized for one hardware configuration than it is for 20,000 of them.
There will always be an advantage to bespoke hardware that is successful at the level needed to program games specifically for it. Steam deck verification, for instance, is a gift provided by uniform hardware. As much as some are loath to admit it, it's true.
