IIRC, Google's server boards run normal processors. It's just the
board was customized to work off single+12V  voltage, with a battery
sitting in between to act as a UPS. The reason was a single +12V
battery per server was cheaper than a huge UPS for a bunch of servers.
Google also use enough boards that it was economically feasible for
the manufacturer to make design changes to an existing board design to
support this.
