As Ray knows, processors are getting more powerful at a very slow rate. Mere doublings and triplings in speed are what we're seeing in the newer generations of processors. (And these require multibillion dollar wafer fabs to build.) A 400 MHz Pentium II, or a 767 MHz Alpha, or whatever, is significant for a lot of business applications--faster transaction processing, better video processing, etc.--but it ain't meaningful for breaking ciphers.

According to trade reports, the 21264 will be available at 800MHz by mid 98 but the die size (a .25 micron die) will need a signficant shrink to make the speed practical (heat and power consumption will be monsterous). It will need a die shrink to a .15 or .18 process in order for 800MHz + Alpha CPUs to be inexpensive enough to produce in volume. A smaller die size
I predict DEC will eventually shift from the Alpha, despite its nice architecture, to the Intel line of processors. Many of us believe the DEC lawsuit, and Intel's countersuit, are negotiating cards in DEC getting a better bargaining position.
increases the number of chips that are "good" per waffer and decreases the finished chips power consumption and heat dissipation. Other methods for dealing with CPU speed (which don't address power or heat directly) include using CMOS alternatives like BiCMOS and Gallium Arsenide. Gallium Arsenide is very expensive, and the element Gallium is a rare earth element, so high production using it is not possible.
This is pure bullshit. The "rarity" of a so-called rare earths material has nothing to do with the economics of production. GaAs is available. What is important is that the overall knowledge about silicon production is so much better, from a production standpoint. And that at small geometries the distinction between Si and GaAs tends to vanish.
