PS5/XBox One 2020 are RDNA 2.0 based GPUs. Nothing Apple will do will match that level. They are both custom AMD SoC with Zen 2/RDNA 2.0 designs.
Does that imply the assumption Apple will do nothing?
There is nothing special about RDNA 2.0. Ray Tracing isn't API / anything GPU specific either. Apple could add Ray Tracing if it seems fits. ( Not saying they will as I dont see how RT will work on Mobile at the moment )
Why not adopt industry standard Vulkan instead of making developers learn another API?
Which "industry" is using Vulkan as Standard? It isn't even standard on Android.
I understand the "Dream" of having a cross platform Graphics API. I was once there too wanting OpenGL to be industry standard. But it simply doesn't work. It never did, and possibly never will.
