I was recently reading Tracy Kidder’s excellent book Soul of a New Machine.
The author pointed out what a big deal the transition to 32-Bit computing was.
However, in the last 20 years, I don’t really remember a big fuss being made of most computers going to 64-bit as a de facto standard. Why is this?
384bit is the memory bus width. AMD’s Fiji (r9 290x) had a 512-bit bus in 2013. Not to be confused with data types used for calculations.
