Petz, Analysis came from Patrick Tanner: Given the available data, I worked out the market share percentages for Intel and AMD. Percentages of Total Retail Sales Reported Calculated Reported <$1,000 >$1,000 TOTAL Intel 59% 71% 63% AMD 35% 29% 33% Other 6% * 4% Calculated: Sales of >$1,000 were 33% of all units. * - assumed all of 'Other' < $1000 Thanks for posting it. From this analysis, it seems AMD has 29% of >$1000 retail market. I think it is safe to assume, AMD gained close to 27% (assuming a prior to Athlon retail market share of 2%). That's phenomenal! A good data point for any body trying to figure out AMD revenues. Also, AMD stock is started taking off, after the commentary that was aired on CNBC about Flash demand. They clearly mentioned that AMD as the big player in FLASH and they also mentioned about the newcomers (compared to AMD) STmicroelct, and Atmel. What I learned from the CNBC blurb was that AMD makes flash devices specifically for the Cellular phone and other mobile markets, whereas Intel specializes in Flash devices for computer systems.

A much more serious Coppermine bug than "boot hang." From Pentium© III Processor Specification Update Release Date: November 1999 Order Number: 244453-009 E46. Snoop Request May Cause DBSY# Hang Problem: A small window of time exists in which a snoop request originating from a bus agent to a processor with one or more outstanding memory transactions may cause the processor to assert DBSY# without issuing a corresponding bus transaction, causing the processor to hang (livelock). The exact circumstances are complex, and include the relative timing of internal processor functions with the snoop request from a bus agent. Implication: This erratum may occur on a system with any number of processors. However, the probability of occurrence increases with the number of processors. If this erratum does occur, the system will hang with DBSY# asserted. At this point, the system requires a hard reset. Workaround: It is possible for BIOS code to contain a workaround for this erratum. [note that Intel does not say whether this has been done or how to do it!] Status: For the steppings affected see the Summary of Changes at the beginning of this section. end quote This table says this *hanging system bug* applies to ALL PENTIUM III processors ever made and that Intel has no intention of fixing it in any future steppings!!! You can also be assured that this bug is much more likely to occur with RAMBUS memory and COPPERMINE PIII's because these are capable of many more outstanding memory transactions. This errata first appeared in the October, 1999 specification. Petz
