I was just looking at THG's Opteron/Workstation tasks review and thinking...
Well, A64 will use the same core as Opteron, right? So let's assume that, per clock, A64 performs identically (which is probably <i>not</i> the case, because of the single-channel DDR). And let's also assume that scaling the clock rates scale the performance numbers linearly, i.e. perfect scaling. So let's try to preview A64@2.0Ghz's performance...
Now think about the benchmarks we saw that compared the 3.0Ghz P4 on Canterwood and a single 1.8Ghz Opteron. I'll give you a little reminder:

*-test results obtained through linear scaling.
Now what about those numbers?... Isn't Opteron's architecture supposed to be equal or better than A64's?... Is my scaling absurd?... Is A64's performance at same clock superior to Opteron's?... Hm...
If I'm not crazy, A64 will very likely be trounced by Prescott at 32-bit. Anyone disagree? With a reason?...
