Fyo,

Your "guess" is 100% spot on ;)

What made me hesitate and say "guess" is that I am not sure if Athlon can pass the critical word, without waiting for the rest of the cache line to fill. In case the whole cache line has to be filled before the processing can continue then that would be the true latency, and DDR could catch up a little. The cache line for Athlon is 64 bytes, which is a product of 8 memory transfers, 8 bytes each. DDR can do the other 7 transfers (after the first one) faster than SDR.
