Both chips have similar (within an order of magnitude) die areas, frequencies, power dissipations, and external pin bandwidth.
If the GPU were truly 1000x more efficient than the CPU, then the CPU vendor could just take 1/1000th of a GPU and squeeze it onto their own chip to double their performance.
(In a sense the trend since the late 90's has been to do exactly this via vector extensions.)
