> The diagrams we show computer science students that purport to illustrate how the CPU, memory, and I/O devices are connected in a computer are woefully out of date and often represent an idealized computer from about 1970 or 1975. These diagrams are, of course, complete fictions when you're looking at a modern server, but people still believe them.
And yet, we still see the common misconception that CPU speed == clock speed.
> It is true that the days of upgrading every year and getting a free—wait, not free, but expensive—performance boost are long gone, as we're not really getting single cores that are faster than about 4GHz.
