It's the memory controller and cache subsystem. Series S talks directly to gddr6 and doesn't need nearly as much die space as all the L3 and big DDR5 memory controllers as the Ryzen APU in the steam deck.

Yes, a 192bit bus will be non competitive even with gddr7.
I upgraded to a 6950xt to play at 4k above 60fps and it works great. Couldn't be happier. Even ray trace in most games, except a few of the heavy hitters.
That's right the 390 was a 512 bit card. And it was a beast. I had a 7970 that lasted for a long time as a capable GPU.
My favorites were the 512bit bus monsters from 20 years ago. With raytracing being so memory and power intensive it kills me that we haven't gotten a monster like the 8800gtx again
Modern CPUs have 512bit registers, and don't need bigger memory addresses. Not sure what the issue is.
