The process used on some older 486
computers to triple the internal processing speed of the CPU
while maintaining the manufacturer's original clock speed for I/O transfers. In
most cases, clock-tripling would normally yield a lower than 100 percent
overall system performance boost (e.g., 30 to 70 percent), not an actual
tripling of the clock speed as suggested by the name.
