What do you mean by this? Doubling the size of what given number?
The labeling of CPU is sometimes confusing, there is a AMD 2400
in this box but its frequency is just close to 2000 MHz according
to /proc/cpuinfo. Perhaps this was meant?
This is indeed intentional. Back around the time when AMD introduced their
XP line of processors, the AMD and Intel processor design philosophies were
going in two completely different directions. The best way to explain it in
layman's terms is this:
The "hertz" number, or "clock rate" of a processor tells you how
many "cycles" it goes through every second. How much "work" is done in a
given "cycle", however, is variable. Intel chose to produce processors with
very short cycles that did little bits of work, whereas AMD chose to
produce processors with longer cycles that did more work.
True, "Hz == Hertz" is a SI unit named after the German
scientist Heinrich Rudolf Hertz means 1/second (second^-1). IMHO
AMD CPU usually outperform their Intel counterparts easily at
least under Linux. That's why I use them. ;-)
