HT = ~72GFlops
No HT = ~86GFlops

FWIW even though using SMT (HT) gives lower Flops it uses more power, ~10% more on my 860, so is probably more stressful than the higher Flops on separate physical cores.
I hope I understood you right, so here it goes (actually, added UnCore variations):
1-LinX_HT_4000-3200-2000_77.65_GFLOPS
2-LinX_HT_4000-3600-2000_78.99_GFLOPS
3-LinX_HT_4000-4000-2000_79.82_GFLOPS
4-LinX____4000-3200-2000_87.03_GFLOPS
5-LinX____4000-3600-2000_87.64_GFLOPS
6-LinX____4000-4000-2000_88.74_GFLOPS

1. 2. 3. 4. 5. 6.
