Hm, something about the new Haswell chips caught my eye.
"On the floating point side, Intel's new Fused Multiply Add (FMA) extension includes both 256-bit and 128-bit instructions. Compared to the conventional separate multiply and add instructions in SSE, FMA doubles the theoretical throughput. In addition, the fused instructions eliminate the intermediate rounding stage which can improve accuracy for some approximation algorithms."
Would this change anything for Stata? (Not before Stata 14 anyway, I am afraid.)

(I also wonder if AVX2 and TSX changes anything.)
