I don't understand why you're making that distinction for Xbox One (actually it could also be made for Xbox 360 10MB eDRAM) but not for PS2 which had a 4MB of very fast memory eDRAM and 32MB of main memory, which was way way slower than Switch unified memory.
That seems like a pretty biased comparison, regardless of the importance of memory bandwidth in game rendering.
