I was quite surprised by HD 3000s beating out Geforce 310s and Radeon 5450s, but then I noticed the clock speed, and I wasn't so surprised anymore.......
On graphics where the only performance output you care about is in one metric, unlike in CPUs that's split between single and multi-threads, it doesn't matter.
It may be high frequency, but they still can fit that in a 17W CPU and maintain about ~80% of the performance of the one that goes into 35/65/95W designs, meaning it still uses very little power.
Advanced power management techniques have rendered the argument "high frequency designs need more voltage, thus more power" mostly useless.
Here, 6990 vs 590: http://www.anandtech.com/show/4239/nvidias-geforce-gtx-590-duking-it-out-for-the-single-card-king/1
Different amount of ROPs, TMUs, shader units, clock speeds, memory frequency, yet in the end they perform about on par and use about the same power.
Performance/Power Design Target X: (Design Black Box - where they can do whatever they want but need to meet the other part of the equation)
