IBM At the Hot Chips 2010 conference, IBM announced their upcoming z196 CPU, which is really, really fast. How fast? Fastest chip in the world fast. Intended for Z-series mainframe computers, the Z196 has a clock speed of 5.2GHz. Measuring just 512 square millimeters, the Z196 is fabricated on 45nm PD SOI technology, and on its surface contains almost one and a half billion transistors. My... Processor is bigger than yours.

Mainframes tend to have Terabytes of ram just for that reason even my schools compute servers that students use have 64Gb ram and 8x cores. Also wasn't it just the other week that that group demonstrated sorting and archiving 1Tb of data in a minute?

I believe there was a graph I once saw that showed a strong correlation between the speed of AI computations and the size of CPU cache. Such computations don't benefit much from faster access to data on an HD but do benefit greatly from data that can be accessed quickly from cache. What I'm trying to say is 1ms vs 100ms is still slow compared to 5-10ns or less.
