Ace's Hardware heeft van bronnen bij Intel vernomen dat er problemen zijn met de trace-cache van de Willamette / Pentium IV. Verder zouden de op dit moment bereikte kloksnelheden erg laag zijn en zou het chippie vol bugs zitten:
Sources of ours told us today that Intel seems to be experiencing problems with the trace-cache in Intel's upcoming Pentium IV. The CPU taped out last month (November '99), 5 months later than planned.Intel's 7th generation CPU seems to be reaching very low clock-speeds at this point in time. On top of that, Intel's engineers still have to sort out a lot of bugs. The Pentium IV does not seem to work properly right now ("they still don't have enough bugs out of it to sample it").
Our sources at Intel did not want to comment on this rumour, but they admitted that "Pentium IV is an extremely advanced design but is unfortunately not on schedule". I personally hope Intel engineers will sort it out on time, because it would unbelievably interesting to compare the Pentium IV and the Athlon Mustang clock for clock and see what technically makes them better or worse than their competitor (I am drooling here).
