Hi Paul
I believe the Formac's card, when it mentions 300mhz is their RAMDAC converter...most
video cards, when they mention a Mhz number that high, its usually for that...some are
350mhz. That would be the digital to analog converter...where it transfers the digital
signal from the computer, into an analog one so a CRT monitor can display it. The
clock speed in a graphics processor works the same way as a regular CPU like the G4
and P3 or Athlon...it just handle graphics though...so the more cycles, the faster it
is....but usally, graphics chip makers like ATI and nVidia...instead of going for
faster mhz every year like in CPU's, they go for different generations of
processors.....example....Motorola went from the 68040 chip, to the PowerPC chip 601,
then to the 603, then the 604, then the G3, then the G4. ATI has gone from Rage to
Rage Pro to 128 rage to 128 Rage Pro to Radeon....with each processor different and
stronger.
