((at the risk of sounding very silly)) there was that Transmeta Efficeon, which matched clock-for-clock performance of Pentium 3, and watt-for-watt was way, way ahead. it's core was 256bit VLIW (no idea if RISCy), and Transmeta's firmware translated x86 code dynamically into native format. if it was launched those days when multicore is a-OK, it'd shine; but back when desktops were singlecore and servers few-core-is, it fell flat because of singlecore performance :-( -- dexen deVries > (...)
