SiSoft Sandra 2004 64-Bit

The 64-bit version of Sandra 2004 has been available for a while, but we did not have an Operating System to reliably run with the 64-bit version.  Sandra 64-bit runs fine on the XP64 preview.  While Sandra is a Synthetic Benchmark, we were curious to see if there would be any performance difference in memory, CPU Arithmetic, and Multimedia benchmarks between the 32-bit and 64-bit versions.  Everything was kept the same; we even used nVidia drivers close to the same version number.  The only difference is Sandra 2004 tests were run on XP Pro, while Sandra 2004 64-bit tests were run on XP 64-bit Preview Edition.

The 32-bit vs. 64-bit results in Sandra are very interesting.  Even in this pre-release version of XP64, the Athlon 64 CPU and Memory Performance is higher than in 32-bit Windows XP.  Mips, which is based on ALU tests, is more than 10% faster, and Integer and Float tests in the Sandra 2004 Multimedia benchmark is 1% to 6% faster.  The only area without increased performance in 64-bit is the mflops component of the Arithmetic benchmark.  If we look closer, this benchmark is a combination FPU performance and iSSE2 performance.  While Floating Point increases some 11.6% in the move from XP to XP64 Preview, the Intel SSE2 results decrease by about the same amount.   The net result is virtually no change in the composite mflops.  We do not know if this is because Intel SSE2 is penalized by 64-bit operation or whether XP64 and/or Sandra 2004 64-bit benchmark require some optimizations for 64-bit performance.    

Super Pi

Super PI is very simple - it calculates the value of pi.  In the benchmark you can select the number of placed for calculation, and we used 2 million places as used in memory tests at AnandTech.

As you can see, Super Pi was exactly the same result in both 32 and 64-bit.

    Have any of you tried to hook a printer up to the windows 64 bit?My daughter is trying to find a printer thats compatable with it
