9x333, 8x375, or 7x428 on a Q6600 - Which is faster?

[graysky]

Since I'm suffering from insomnia and have nothing better to do at 2 AM, I compared 9x266 @ 1:1 (so memory was 533 MHz) and 9x266 @ 3:2 (so memory was 800 MHz) on my Q6600. All other settings were held constant; timings are 4-4-4-10.

All the apps run faster at the higher ratio:

Two synthetic benchmarks:
-Super PI mod (16 M) ran 6.2 % faster (10m 3.125s vs. 9m 25.859s)
-Winrar internal benchmark (101 megs) ran 23.6 % faster (1329 KB/s vs. 1643 KB/s)

Three real-world benchmarks:
-Winrar running my backup batch (about 1.3 gigs of files and then generates 5 recovery volumes) ran 15 % faster (133 s vs. 113 s)
-x264 encoding a 720x480 mpeg-2 ran 4.3 % and 0.4 % faster on the first and second passes respectively (126.95 fps/33.92 fps vs. 132.36 fps/34.07 fps)
-Photoshop resizing 44 files (2472x3296 --> 768x1024) then applying USM ran 5.2 % faster (58 s vs. 55 s)
