[2nd attempt after several hours]
PIII's were 100mhz and 133mhz bus. Most of the PIII's ending in "33" or "66" were 133mhz bus (633mhz, 733mhz, 766mhz, etc). There are also 50, 55, 60 (old Pentiums and some Pentium Pro CPU's), and 200mhz bus. In the case of the 200/266 & 400mhz, these are not actual bus speeds. I don't know why AMD (200 & 266mhz) and Intel (400 & 533mhz) call it that. I've never looked into it before or given it much thought. They still operate on a much slower system board or memory bus. The 200 & 266 are 100 & 133mhz mobo buses respectively. The 400mhz FSB P4's are 100mhz bus; and the newer faster P4's w/533mhz FSB CPU's are 133mhz board bus. For an example; the P4 1.6hz is so called "400mhz FSB", yet it uses a 16x multiplier, which of course is 100mhz FSB. (Whomever posted the original question: Win95/98/SE/ME does not "see" dual CPU's. So if you're using a dual CPU setup, you have to be using NT, 2k or XP to benefit from it). -Clint Happy New Year to all & God Bless Clint Hamilton, Owner Want to exchange links with us? http://OrpheusComputing.com � ----- Original Message ----- From: <[EMAIL PROTECTED]> Howdy... There is one fallacy I see in all of this, as most people are not fully familiar with how multi-processor systems work. First off, a multi-CPU system executes a program on only one processor, otherwise several problems due to missing information. Now in regards to bus speeds, they were 33, 66, 100, 133, 266, and finally 400. I cannot comment on whether the P3 was a 100 or 133 MHz bus, but regardless, it was an advancement over the P2. I just wonder what is going to be done with the Itanium and trying to keep it backwards compatible with the Celeron, Xeon, and Pentium series. I think AMD has won the battle, AND the war. Richard -----Original Message----- Of Peter Kaulback The P3 800 will be much faster than the dual P2 333, as the P2 is the first generation of the P2 class which sported the 66 mhz system bus while the P3 has the 100 or 133 mhz bus (correct me if I am wrong on the exact figure:)). Secondly for a dual you should double the ram to compare against a similar single cpu system. If you can afford it then try to get a dual P2 400+ mhz system.
