<Ten, if latency is four clocks, then four 200 MHz clocks is half of four 100 MHz clocks. Or does the 200 MHz only apply to the throughput?> The 200 MHz clock speed applies to throughput. Latency stays the same. So if the number of clocks between the read request and the first chunk of data was seven on the 100 MHz bus, that number will increase to 14 on the 200 MHz bus. Actually, the K7 bus is a 100 MHz double-pumped bus. That means that the requests, snoops, and other protocol stuff occurs at 100 MHz. The data is transfered on both edges of the clock, much like AGP 2x. So, like you said, the 200 MHz clock really does apply only to the throughput. Tenchusatsu
