Open a large page on your phone and time it. Now open the same page on your laptop/desktop while connected to the same wifi and time out. The laptop will be able to render the page faster than the phone. This also holds true with the 3GS since the proc is 50% faster and memory is double.
It's more than a 50% clock speed increase. The processor has L2 cache, and a better architecture. Like Anandtech said, it's about like the comparison between a 486 and a Pentium. The Pentium 90 was faster than the 486 DX4-100 for the same reason.
I've also heard reports that the processor actually jumps up in speed to meet demand.
