3D Mark 11 (Physics)
by Anand-Lal-Shimpi (Jun, 2013)On average I measured a 15% increase in the subset of game tests I was able to run in Taipei, and a 13% increase in performance across our 3DMark tests.
3D Mark 06 (CPU)
Passmark
by Anand-Lal-Shimpi (Jun, 2013)PCMark 7 and single-threaded Cinebench show a 3 - 6% increase in performance, while multithreaded Cinebench and x264 show a 3 - 5% decrease in performance.

The combination yields a peak sequential throughput of 665MB/s, which is pretty fast for an Ultrabook.
Under heavy load I wouldn’t expect any substantial increase in battery life, however most notebook usage models boast significant periods of idle time.
