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 traditionally had relatively slow processors, coupled to memory that was more than able to keep up with it...
It's low end machines which have faster processors that are severely bottlenecked by memory speeds, because buyers look at the processor speed and don't consider other aspects of the system...
I would be extremely surprised if IBM hasn't designed a suitably fast memory system to go with this processor.
