Hi all; P4 defective:

Test Uncovers Pentium 4 Flaw
By John Yacono, CRN 12/27/00
There is a flaw in the support chips for the Intel Pentium 4 that impacts system performance in some circumstances, the CRN Test Center has discovered.

Specifically, passing large amounts of data over the PCI bus can introduce latency -- or computing delays -- into the system.

An Intel Corp. (stock: INTC) spokesperson said the chips were shipped to motherboard and system OEM partners since the Pentium 4 launch Nov. 20.

Revised chips will be sent to OEMs in the next few weeks, but it will take time for them to pass OEM tests and finally be introduced into the channel. The speed of that process will depend on the OEMs.

When asked if streaming other high-bandwidth data types on the PCI bus, such as between SCSI cards, might also inspire system latency, Intel indicated that bus mastering devices would not be subject to the problem.

However, the Test Center has done the same DVD test on older, slower Intel-based systems without any dropouts.

That would indicate the latency introduced is significant enough to allow Pentium III architecture to outperform the Pentium 4 architecture for at least this form of DVD playback.
