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.

Doubtful. The cost is very high. That's part of why companies like, say, Google, don't even consider them for their grunt work. if I were coming up with something scalable, today, I'd be looking at many cheap boxes, and handling fault tolerance with a proxy layer that caches workloads until they are sent back complete, with as much testing of data correctness as seemed reasonable (FI, if scaled out enough, sent each workload to two machines, and verify CRCs on their results, before returning the results).

There will be a continued demand for big iron (sometimes you'll just need throughput...and maybe need to run legacy code that isn't x86), but I don't think anyone will be moving towards them in any large numbers. Atom and Bobcat derived servers are much more the future, even if you treat cloud computing as a fad.
