Intel has upgraded the front end of the Skylake core to allow a dispatch of six micro-ops at once, up from four on Haswell. This allows the queue to be quicker, but also the dispatch of micro-ops from the queue to the execution units has increased to six.

This will allow for fatter dual threads in a core which has for example improved throughput by over 20% in a spec subtest.

p.s. this subtest also has been decomposed to work on more than one core in single-thread mode.
