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.

You are correct, I was just giving an example as to why really large L1 caches are not only useless but become problematic, touching on the fact that these cores are used in SMT in which case context in the L1s actually has an effect.

Oh, OK, I didn't notice the part about SMT.
