What is included in "the CPU portion". Does that mean just the CPU or does it included all of the CPU support like memory, clocking, etc?

Fastest Processor Under 1W?

The Atmel AT91SAM9G20 consumes 80mW at 400 MHz. That leaves you some power budget for your memory, etc.
The Intel Atom Z500 at 800 MHz has a TDP of 0.65W, but by the time you add the necessary support chips, it will be significantly over 1W.
1W=500ma * 2v 500ma / 1000000 processors = 500na per processor but nano power pic means 20na, 40nw for deep sleep +-50na I/O pin leakage current lowest listed nanopower pic running I could find is 110uA current @ 2V and 1MIP

1mip/110uA * 2v = 1mip/220uW per pic
1W/220uW per pic = 4545 pic/W = 4545 mip/W =/= 1000000 pic/W
68 rows and 67 columns would be 4556 chips
parallel Forth processors @ 1.8V
700mip/7mw per core = 100mip/mw = 1mip/10uWpackaged with 4/24/32/40/48/144 core per chip
1 GA4 = 2800mip/28mw 8pin 1 S40 = 28000mip/280mw 88pin 1 144 = 100800mip/1W 88pinBest Wishes
