Some of us remember what happened when a few sites had early benchmarks of an engineering sample of the original Athlon. The final silicon proved to perform a lot better. Note: the site may be kind of slow probably for the obvious reasons. Thanks to one of you who e-mailed the link. The names have been changed to protect the innocent.
Update Damage: This is really fun, but I am a little concerned about their memory latency numbers. They haven't specified what units those numbers are in, but latency numbers come out of programs like cachemem in CPU cycles. Obviously, processors with higher clock speeds will see more clock cycles pass per second than processors with lower clock speeds. One must convert those numbers into comparable units, such as nanoseconds, in order to compare CPUs at different clock speeds. I do expect the Athlon 64 to have low memory access latencies because of its integrated memory controller, but I don't think the gap will be so great as the X-bit numbers would seem to indicate.
Just my two cents.
