Kash - Re: It will be interesting to compare with SPEC numbers for the workstation K7's with 8MB full speed caches running DDRDRAM at 266Mhz. If they get these clocking in the 700-800Mhz range I suspect it will smoke the current top dog. I seriously hope you don't think that. If you do, maybe you should take a look at SPEC.org numbers: HP9000/N4000 (440MHz PA-RISC 8500) SPECfp : 48.7 / 51.4 SPECint: 30.8 / 34.0 OUCH! Let's take a look at some speculative, approximate K7 numbers and then let's mess it up completely by doing some totally unwarranted linear extrapolation (from 550MHz --> 800MHz): SPECfp : 23 --> 33.5 SPECint: 25 --> 36.4 As you can see, the K7 (err.. Athlon) may get close in integer, but it won't get ANYWHERE near the PA-RISC in floating point. And I certainly wouldn't call this 'smoking the current top dog'... Ok, ok, so this isn't the K7 with PC266 DDRDRAM and 8MB full-speed cache (which may be DDRDRAM), but I still don't see how you are going to make up the HUGE gap in floating point performance. --fyodor
