From sandra site:
"The (E)MMX, 3DNow! and SSE(2) versions compute 2/4/8 Mandelbrot point iterations at once - rather than one at a time - thus taking advantage of the SIMD instructions. Even so, 2/4/8x improvement cannot be expected (due to other overheads), generally a 2.5-3x improvement has been achieved. The ALU & FPU of 6/7 generation of processors are very advanced (e.g. 2+ execution units) thus bridging the gap as well. We found it useful to see the differences between the old and new versions of CPUs within a family as well as comparing similar CPUs from different manufacturers (e.g. Intel vs. AMD)."

mean to say that particular AMD processor onli allows 4 Mandelbrot point iterations whereas the Intel processor allows 8 Mandelbrot point iterations???

I guess a stands for AMD and I stands for Intel. If you look at what Sandra site says it seems that only 2.5-3 at the same time are achived (per core). And yes Intel has better SSE implementation.

Not quite sure, but pentium should be better. First, it uses sse2 and second it uses x8 in integer test and still scores onl ~12% lower score. In float test they scores very similar but intel still has sse2.

Right on target. I think it would be better said that we are doing omething and at the same time we don't know what it MEANS. In case of benchmarking it means that we are supposed to know how it affects on coputer performance. For example, will better sse3 scores means that my computer will faster open word documents (I know this is trivial, it will not, but I am too lazy to think of some working example).
