Dunno, the vast majority of phones, tablets, laptops, and desktops have had 64 or 128 bit wide memory interfaces for decades. Apple has a high profit market and a vertical market, unlike the competition. Apple skipped GPUs and did it their own, and the GPU is the primary justification for the 100, 200, 400, or 800GB/sec available with today's apple silicon. Don't think Intel, AMD, or phone/laptop/desktop ARMs (from anyone but apple) have any near term plans for great memory bandwidth. Sad. Obviously AMD can do it, they ship a much nicer memory interface on the PS5 and XboxX, but don't ship anything over 128 bit until you move up to $$$$ workstations with the threadripper (256 bit), threadripper pro (512 bit) or Epyc/Genoa (768 bit) wide memory. Even the Epyc/Genoa socket @ 460GB/sec doesn't match the M2 ultra (800GB/sec), despite the bare CPU being more expensive than most of the Mac studios sold.
