Now we can understand

IIRC there was an announcement here (poss Arstech) which described the new chipsets which Intel was introducing.

And mirabile dictu, there are upcoming chips *which have no HT*. Cannot remember if the i9 does or doesn't, but the i7 is the other way round. And this does not depend on the core count.

So now we know why THAT has happened. No HT -> no slowdown from contention for the FPU, probably minor slowdown relatively but obscured by a clock speed jump, of course.
