Jep the difference is roughly 1 Watt and without Audio overhead and with default EVR (0.5W-1W still optimizing measuring) we are @ 5W (Intel Decoder) and 6W (Lav Video) (though if you calculate all the issues with DXVA2 into that with different renderer special adoption of Splitter ect i find this 1W very acceptable
