"The Power8 chip is implemented in IBM's familiar high-k metal gate processes, which include copper and silicon-on-insulator technologies in a 22-nanometer process. The precise transistor count was not given during the presentation, but the Power8 chip weighs in at 650 square millimetres; this is a bit bigger than Power7+, which used a 32-nanometer process, had 2.1 billion transistors, and a surface area of 567 square millimetres."

a 22nm SOI chip with a die size of 650 sq mm. goddamn thats a hell a lot of transistors. i don't know what the yields on that chip would be like. but they must have a lot of redundancy built into the chip. and a lot of salvage SKUs

Go find a picture of POWER7/7+/8 package. It's huge.

good lord, the complete CPU is like the size of a que card.
and the silicon itself is what, a 1-1.5" wide?
