Intel has delayed delivery of its long-awaited Pentium IV processor, according to PC makers.
Two PC manufacturers said Intel notified them that the processor would not be ready for delivery by the end of October, as expected, while a third said Intel indicated it may not arrive by then.
Other suppliers said Intel had told them that the processor would ship three weeks late.
Reports last month said that Intel had suggested a release date of 30 October. The problems with Pentium IV are faults in the i850 Tehama chipset which is affecting graphics performance.
An Intel spokesman said, "We have always said that we would release the Pentium IV processor in the second half of 2000, and that is on track," although he did not reveal exact dates.
Intel will be hoping that Pentium IV, which is expected to be introduced in 1.4 GHz and 1.5 GHz version, will solve some of the problems that have plagued the Pentium III, as the company improved the clock speed. A recent example of this was when Intel had to recall the 1.13 GHz Pentium III processor because of a serious problem.
