"..to be honest about performance, everyone ... knows that when software is optimized for the P4/RDRAM, performance is order of magnitude better." Those determined to believe this need to examine some facts. Take a P4 with two RDRAM channels and specifically designed dual-pass compiler: spec.org Compare the numbers to an AMD Athlon 1.2GHz single-channel DDR system, compiled mostly with Pentium MMX optimizations: spec.org Only 2 P4 numbers exceed Athlon by 2-something times, several others are 2%-50% better, and in five benchmarks the 1.2GHz Athlon wins against 1.5GHz P4. I do not think this qualifies as P$ is "order of magnitude better". More, as it was mentioned before elsewhere, these scores come from a very specific applications where the compiled code is optimized only for the particular set of data. No off-the-shelf applications have this luxury, and never will. So I would not translate these SPEC2000 numbers into real-life "standard equipment" applications too directly.

Ponderosa, if you want to be honest about performance, everyone, (other than those determined not to believe it), knows that when software is optimized for the P4/RDRAM, performance is order of magnitude better. It is easy to optimize the software so, I'd say that it is just a matter of time before P4/RDRAM wins the upgrade cycle and becomes standard equipment. From 1997: if you want to be honest about performance, everyone, (other than those determined not to believe it), knows that when software is optimized for the Alpha, performance is order of magnitude better. It is easy to optimize the software so, I'd say that it is just a matter of time before Alpha wins the upgrade cycle and becomes standard equipment. Scumbria
