This reminds me when Intel "tried" to sell overclocked PIII (Coopermine) @ 1.1GHz (IIRC) and then recalled it when it failed because it was an effective overclock (processors were unstable and overheating).
(It worked up to 1.2GHz, maybe 1.3GHz when they went to Tualatin based PIII - those also kicked the behind of higher clocked Willamette P4s)
Well to be fair pretty much everything kicked the P4, the only way for it to compete was "let's go higher" (clock wise). Then they reached the higher ghz barriers and were in deep trouble until they figured out to re-purpose their core-m mobility chip into what become the basis for all their desktop core and i* cpu. Meanwhile AMD was owning everything.
Without their anticompetitive behavior, Intel would have lost their place back then already.
