Tenchusatsu, Thanks for the info. Translating this to Thunderbird vs. Willy, it means that Willy's quad pumped 100 MHz system bus will have 50% higher burst transfer rate, but in some cases, double pumped 133 MHz Thunderbird will have an advantage, cutting the overall Willy lead over Thunderbird to less than 50% overall. A question for the thread: Does anybody know if every Thunderbird chip will be 133 (x2) MHz FSB capable? Joe

Re: No, there are significant differences between quad-pumping a 100 MHz bus and double-pumping a 200 MHz bus... Tenchusatsu, Thanks for another informative post. Regards, Dan

Hi Tenchusatsu; Re quad pumped versus double pumped buses. Suppose you had a double pumped system, but you replaced the system clock with a half frequency clock, and also put a 1 to 2 clock multiplier on each chip. The result could be called a "quad pumped" bus, but it would exhibit all the behaviour of a double pumped bus. That is, request signals, cache snoop signals, bus arbitration, etc., would still be running at the same frequency, all that would change was the system's main clock. But then again, who cares, it's just words. -- Carl
