The AIU (Integrated Artificial Intelligence Accelerator Unit) is a
portion of each chip in a z16, maybe about 1% of chip real estate, that
contains something they call the "Matrix Compute Array" containing 128
"Processor Tiles" (whatever those are). To me, those PT's make it look
more like a GPU than FPU. The AIU also contains controlling AI firmware
and has direct access to the chip's cache, something a PC graphics card
might have a bit of trouble doing.

I'm guessing that IBM uses FPUs which can reach speeds of 5 exa-FLOPs. I have
no clue how they are making the leap from computations to decision processing.
