> The computer I'm writing this on has 64 GB of RAM, 1024 times as much. By comparison I have a 20-core Intel CPU with up-to 3GHz speed or somewhere around there, even pretending each core could run at that max speed simultaneously (which they can't), that's only 133-times as much CPU power.

This nerd sniped me a bit. Your calculation on the amount of CPU power is too low, because of the change in IPC, but for the things we have benchmarks for, it isn't multiple orders of magnitude off like I expected. Looking at Cinebench 2003, prime95, and a few other benches, I get somewhere between 300x and 850x faster for the modern CPU over the Pentium 3.

For me, the biggest change in performance in my life was going from spinning disks to SSDs. That change felt bigger than any other leap by a long shot.
