Re: "One anonymous person posted on a messageboard that a 1.5GHz P4 will do 524 in specfp2000 and 502 in specint2000 with the 5.0 compiler. Of course, this IS a random person so it should be taken with a BIG grain of salt. But the numbers fit the speculation that P4 isn't too good in integer clock for clock. THe fp score seems reasonable because of SSE2" Those numbers are far far ahead of anything AMD has dreamed of and are world class, even in FP, and those numbers still may be conservative, we'll just have to wait and see.....<G> I think it's time to realize that regardless of the IPC, the real issue is total performance from a given process. Who cares if the IPC is slightly lower, if the overall performance is higher? EP

Of course, this IS a random person so it should be taken with a BIG grain of salt. I have reason to believe that those numbers are accurate, or at least in the ballpark. > But the numbers fit the speculation that P4 isn't too good in integer clock for clock. It's not that bad in integer. But in defiance to Elmer's suggestion that the score here is "far far ahead of anything AMD has dreamed of", I have to say that it is not leagues above everything that we see today, and the specint score will likely be approached if not matched or overcome by AMD's highest offering at time of solid product availability. > THe fp score seems reasonable > because of SSE2. The fp score is great, but I don't know if it's because of the compiler taking advantage of the double precision floating-point SIMD. I'm not completely sure whether i5.0 does or not (and if that, I'm not completely sure if it does it well). However, what does give Willamette a huge boost in performance is the really, really high bandwidth between the cpu and the memory. Specfp really, really loves memory bandwidth, I've been told.     -JC
