--- Comment #4 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Tests are run in FullHD.  BYT has (a lot) less memory bandwidth available than
Core machines, compared to the memory bandwidth taken by FullHD frames.  On
IVB/HSW, Batch0 test isn't memory bandwidth bound (at least as much as on BYT).
