Transmeta Founder Talks Chips 153
gManZboy writes "Dave Ditzel, CTO and Founder of Transmeta (you remember Transmeta? weren't they supposed to kick some Intel booty?) sits down and speaks with Alpha and StrongARM chip designer Dan Dobberpuhl about the history of CPUs, where they're heading, and how the heck we'll keep up Moore's Law (if we can)."

DOBBERPUHL The power is dissipated mostly in the transistors, either as they switch or as they just sit there and leak.
You can calculate the dynamic power dissipation with the formula P = CV2f, where V is the power supply, C is the capacitance that is being switched, and f is the switching rate. There are some additional factors, but fundamentally the dynamic power is given by that formula.

How Moore's Law affects some computer users (Score:5, Interesting)
How Moore's Law affects some computer users as measured in the time it takes to do something, like render a page of a document on the graphical screen in a window opened for a word processor, is shown as an example here:
There will still be needed even faster CPUs for many things. The use of cryptography will certainly be increasing and that is a big need for more CPU speed. Larger, more bloated (in terms of steps of code, in addition to RAM and disk space), operating systems and applications will need faster (and larger) CPUs, too (though many have learned to avoid these steps to avoid the costs of upgrades to software and hardware).
But the market for faster CPUs will gradually be leaving behind more and more people who do the kinds of things that just don't need it. The threshhold has been reached for many, and soon will be for many more. Hopefully new and expanded uses will keep (or restore) the markets in a thriving condition.
