ARM, Mips and SH all beat the pants off x86 in the MIPS/watt and also in
the FLOPS/watt department.
Nobody seems to be interested in clusters built with these
architectures. We started design on a 1TFLOP cluster a few years back
based on a 64/128 bit MIPS cpu by Toshiba (similar to the emotion engine
in the Playstation2). It would have fit into a single 19" rack and
consumed around only 6,000 watts.
