The Machine Room is Back!
This is the recovered Machine Room from 2005. Please don't expect wonders. The look and feel of this site is nine years old, and so is its code. Some of the functionality has been recovered while the rest of the site is modernised and restructured. Watch this space!

CPU clock rate is not a measure of a microprocessor's speed compared to other microprocessors. The comparison is valid only when comparing certain microprocessors within one family of chips. For example, the Zilog Z-80 at 3.5 MHz is slightly faster than the 6502A at 1 MHz, but not faster by a factor of 3.5. CPU (and computer) architecture is fundamentally important here. Having said that, this chart shows how clock rates (not computer speeds) have increased over the past decades. 'Speed' is a vector quantity: a computer may be incredibly fast at one thing, but dead slow at another. Plus, one microprocessor may execute commands in fewer clock ticks than others.
