http://en.wikipedia.org/wiki/IBM_z196_(microprocessor)
Highlights:
-IBM revealed more details of its 5.2-GHz chip on Tuesday, the fastest microprocessor ever announced, the z196.
-Contains 1.4 billion transistors on a chip measuring 512 square millimeters fabricated on 45-nm PD SOI technology.
-It has four cores, and each core has six RISC-like execution units, including two integer units, two load-store units, one binary floating point unit and one decimal floating point unit
-Each *core* contains a 64KB L1 instruction cache, a 128KB L1 data cache, a 1.5MB private L2 cache per *core*, and each *processor* shares 24MB of L3 cache, and a shared 196 MB L4 cache can be added
- The design allows each processor to share cache across two SC chips, for a potential total of 192 MB of shared L4 cache. In total, a z196 processor can have 376 MB cpu cache (L1 + L2 + L3 + L4) that it can address before hitting main memory!
Seems pretty sweet and all on 45nm! Now, I just need an Intel or AMD chip that will do 5.2Ghz and not cost tens of thousands of dollars
