Finally from Sandra 2007 we have Sandra 2007 Power Management Efficiency

Benchmark the power management efficiency of the processors. Shows how efficient the power management of your processors is. The ability of the processors to step-down in frequency and voltage at different workloads is measured. The more a processor steps down in both frequency and voltage the better the score at the specific workload. The test stops when the workload is too great the processor even at 100% efficiency.

The ALU/FPU score is a geometric mean based on the whole range of workloads; thus the power of the

processor does matter in obtaining a higher score.

The Power Efficiency score is a geometric mean based on the supported workloads only. Thus the power of the processors does not matter. (Higher is better)

For both processors I have the Cool and Quiet and/or Speed Stepping turned off.

Hmm, I see a pattern here, the X2 seems to have a very large advantage over the 631.

Now for Super Pi 1M

We know what Super Pi does, I am calculating pi to 1 million and seeing who is fastest here. Technically this is Super Pi mod 1.4.

Here again we can see that only by overclocking the 631 can we see it beating the X2.

Now let’s see how long it takes to encode or re-encode a video file. The file is an AVI file that is being converted to MPG. It is 3 minutes and 48 seconds long, with 5720 frames and is 70.5 MB in size.

Even at 4 GHz the Intel 631 can’t compete. One thing to note is that (normally, automatically) TMPGEnc does utilize both cores of a CPU for the recode process, how it handled the Intel CPU I’m not sure.

You may notice that I didn’t run any gaming benchmarks or 3dMark stuff as my X2 system has a 7800GTX in there and against an ATI Radeon x1300 there wouldn’t be much competition, and I didn’t really want to remove my 7800 from my liquid cooling loop just to re-install it yet again….
