Some of us haven't been overbuilding PSUs
I have a nice 120W TGP 1060 currently do go with my hungry CPU. ~200W is kind of what I'm looking for max. Nvidia used to be efficiency kings, even on a less than cutting edge process - I was expecting better now they finally moved to a smaller node.. only we now know that was not such a good node.
Cat linked an answer in Reddit on that one:

The FP32 throughput is doubled when you aren't doing INT32 so Nvidia are counting that as double the cuda cores, but it's not actually double the cores so performance isn't the same as scaling previous gen.
