As you wish. 
It is the Exponetial X704 PowerPC Processor. 533MHz.  The Process
is BiCMOS.  Unlike Intel's BiCMOS process, The entire core-logic
is bipolar. Only CMOS is the cache.  Most of the RISC CPU's are 
strait CMOS.  Intel's BiCMOS Process uses very little bipolar logic
mostly CMOS.  Voltage and power consumption i don't know yet but I would
assume not more that about 40-50Watts at between 2.9 - 6 Volts 
This probably would not be much of a concern for integrators because
the PowerPC comes usually built into the SystemBoard Some also soldered
onto a daughter card.  Rumor has it that the X704 can emulate X86
instructions
faster than the fastest PentiumP5 but that remains to be proven to me.
