Sapphire HD5770 Vapor X Edition 1GB

Today we are using a Keithley Integra Model 2700/E and we are measuring power consumption at VGA card inputs, not full system drain. To test load we first fire up Crysis Warhead at high image quality settings then we follow up with the synthetic Furmark which loads the GPU beyond game engine levels … Furmark is not a particularly realistic reading, but its interesting to document.

The Sapphire HD5770 is taking a little more power across the board, but its barely noticeable, a few watts at idle and 4 or so at full load situations. Less than 90W when gaming is a particularly impressive figure.
