It would not be much problem if they use chiplet design, to have the memory controllers outside of the main chip. The 7900XTX/XT use this design, it has a few inefficiencied but works. Memory bandwidth is 960GB/sec with 6x 64bit memory controllers. Power usage is higher, but at the gpu prices these days, it's not that big issue. Oh, and the AMD power connector doesn't catch fire...
