Yes, HTT doesnt mean anything, but the cpu interntal clock does, I think. For the 305x9 it was at x3, for the 250x11 it was at x4. So it cant mean anything since it was higher for the 250x11 yet I got a lower score. Also at 305x9 my memory read/write tests showed about 70-100 more mb/s than at 250x11. Cache too. My ALU results didnt really change much, however the FPU test results were significantly higher.
EDIT: Notice how daddy's score was about 500 points higher than the guy below him who had the exact same cpu/speed, and an even higher memory speed, but daddy's internal cpu clock was higher so he got about 500 points more.
