Odd that BGA processors are using 12V instead of logic level voltages.


Then they would need around 100A at 3.3 volts. The voltage drop
would be a big problem. I'm sure there is a DC to DC converter near the
chip, like used on computer motherboards.


I'm surprised they don't use some sort of liquid or heat-pipe plumbing to
remove all that heat. Wasn't it the CRAYs that used liquid Freon to flood
the processor cabinet to dissipate al the heat built up?
