I want to start this one off by ensuring that everyone is aware that this is not a review of the Radeon RX Vega 64 Liquid Cooled Edition.  What this is however is a look across 15 games the performance delta between the ‘balanced’ and ‘power save’ settings.  RX Vega 64 launched two months ago as of the date of this publication on August 14, 2017.  Having been available since then there are plenty of comprehensive comparative reviews, I urge you to seek those out if you’re looking for in depth comparisons.

One of the most critical aspects of Radeon RX Vega 64 has been its power consumption, which seems to be sensitively effected by clock rates, so we wanted to explore AMD’s built in solution to help reduce power draw.  That is our main focus with these results.
