The gap has not closed - the gap has moved.
The new mobile GPUs are close to Desktop performance from 2 years ago. The new Desktop GPUs are nuts.
2 years ago, mobile GPUs were close to Desktop performance from 2 years before that.
For example, go to Vantage (I'm having trouble finding any gaming benchmarks of the 7970m):
http://community.futuremark.com/hardware/gpu/AMD+Radeon+HD+7970M/review
The 7970 tops the chart in performance, the 7970m falls just above the 470, so probably close to the 480 -- a 2 year old card.
Also check specs (7970/7970m):
Stream Processors: 2048/1280
Core clock: 925/850
It's the same architecture, so a card with fewer SP's and a 200w lower TDP can't be faster. It breaks the laws of physics. The 7970m is really a downclocked 7870.

Back from the grave and working on textures.
