Except it's not. There is a current clear benefit from 64-bit registers - the amount of RAM commonly used in desktop computers has exceeded the number of bits addressable with 32-bit registers. It might be a while before we need to go to 128-bit memory addresses, given that (according to wikipedia
), the estimated total amount of digital data stored worldwide in 2010 was 2^70 (~1.2 zettabytes).
Do you have an actual reason for needing 128-bit arithmetic on your CPU? Or do you just think larger numbers must be superior, because, well, biggerer is betterer, duh!?
edit: 128-bit technology already exists, of course. GPUs commonly use 128 or 256 buses and have done for years. The Cell processor also has a number of 128-bit registers, for that matter.

You need a good business case for architectural changes - "just because" doesn't tend to cut it.
