Intel has confirmed it is still on schedule to ship Merced sometime in 2000, with production samples going to its customers in June.
That follows claims from an Alpha developer on the comp.archnews forum that the Merced platform is dead.
According to the engineer, IA-64 has a number of features that will be very hard to implement. Predication, he says, is very complex with multiple outstanding loads that depend on the memory consistency model being used.
"Even the stuff that Intel has talked about aren't really simple to implement with any great performance. It appears Merced is dead. It rests on HP's chip in 2001 or 2002 to see where things really are. Three more years, do you really want to wait?" the message reads.
However, an Intel spokesperson said the Merced project was still firm. Rumours of its demise are untrue.
Meanwhile, reports on various hardware sites that Celerons are not locked against overclocking are also untrue, Intel is insisting.
Dr Tom Pabst, who edits Tom's Hardware Page, said he has definitive word from an Intel employee that the current generation of Celeron's do not have overclocking protection built in.
But an Intel spokesperson in the UK has re-iterated his warning to enthusiasts that they should not rely on it being possible to overclock Celerons.
He said that at the moment, a number of Celeron processors are available that can be overclocked. But as Intel increases its production, consumers will find chips are prevented from being overclocked.
