While you are correct, the Kabylake processor that the Razer Blade uses is a low power 15W TDP chip. By nature this means that it is still slower than the range of 28W TDP Skylake processors the new 13" MacBook Pro family is receiving in this update. The 28W TDP variants of the Kabylake family is not yet available from Intel.
