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.

This has been discussed a billion times already ;) Some things just don't scale well accross multiple cores, if they scale at all. As an example, for physics simulations, interactions can become a major nuisance when you have parallel processing in mind (they are a nuisance for all kinds of calculations, anyway).

So along with the current trends towards hundreds of low-performance processor cores, making individual cores faster is still a good thing for some problems, as long as the bus bottleneck and some relativistic issues concerning the size of electronic circuitry can be worked around ^^
