> Well, it's rather imprecise to compare the performance of MIC and a laptop CPU simply based on clock rate. IIRC, the current-generation MIC is using a low-power core design, based on the Atom series. It lacks advanced features like out-of-order execution which is commonplace in desktop CPUs.

No, the current generation KNC is based on much older core, the next
one KNL will based on Atom's core. That's part of the story behind
performance expectations. For ALU-bound computations we could try to
do better estimations using Intel's spec - if it is publicly
available.
