Hi
I always try to build a period-correct PC, and I read a lot of related articles. However, there are some gaps in my knowledge, and I feel that the Wiki and CPU World also use incorrect dates in some cases. For example, the Pentium III roadmap. It seems to me that they had a planned roadmap and an emergency roadmap related to the direct competitor Athlon. These affect the available CPUs on the market.
Like... dates from the Wiki:
Feb 1999 - Pentium III 500 Katmai
May 1999 - 550
Jun 1999 - Athlon 600 (the clock war started)
Aug 1999 - P3 600. It uses 2.05v instead of 2v. I'm not sure if it was in the roadmap origially.
Oct 1999 - P3 Coppermine 700, 733 release
Dec 1999 - P3 800
March 2000 - 850, 866 (planned), 1000/133 (emergency)
May 2000 - 933 (planned)
Jun 2000 - 1100 (emergency)
Jul 2000 - 1133 (emergency)
1000/133 - It was initially released in limited quantities, available only to major OEMs for months. Practically, you could not purchase and build your own PC with this CPU until late 2000.
1133 slot1 - This CPU does not exist. In the middle of 2000, Intel could showcase selected CPUs with special microcodes to ensure stability.
Higher-clocked FCPGA CPUs - These were not available until late 2000 because Intel aimed to promote the 820 with RDRAM, and the 815 was only available with Socket 370.
Higher-clocked CPUs with 100 MHz FSB - The BX was also competing with RDRAM. They were delayed until late 2000; the highest-clocked 100 MHz CPU was the 850 since March.
So, this is a theory based on articles, and I haven't really found any clues regarding when and how the higher-clocked 100MHz and the FCPGA versions were released. Please help me find sources to clarify the dates. I am mostly interested in the top-of-the-line CPUs, such as:
1000/100 Slot1 (November 2000?)
1100/100 FCPGA (2001?)
1133/133 FCPGA (2001?)
It would make sense to me if Intel stopped blocking the faster, SDRAM-related CPUs (Slot1 with 100MHz and FCPGA) after the release of the Pentium 4 in November 2000, and these CPUs were available around this date on the market.
