Megahertz isn't everything!
Most people think "Yeah look at my awesome 2.2Ghz processor I jsut got!', butt little deos he know that Mhz isnt the only factor in processor speed. While comparing many benchmarks I notices that the Athlon 1900+ and the 2.2 P4 Intel have similar performance specs even though the AMD is only running at 1.6 Ghz. This is because the performance of a CPU is determined on: (work per cycle) * (clock speed (Mhz)). This means that if a 2000Mhz Intel does a work of 4 units per cycle and an AMD running at 1400 Mhz does a work of 7 per cycle, you'll notice that the Intel scores 8000, while the AMD scores 9800. This is why AMD can have a cpu running at a lower clock speed than Intel and still have the same amount if not more performance.
