Recently this has come to light during my own research into mobile GPUs that are currently available on the market as I've been considering replacing my aged i5-520M laptop with 5650M GPU. I had even placed an order and paid for a machine but after reading much about the issue (none of it from AMD themselves other than "For those with 7970M - Enduro issues are also being investigated;" by http://twitter.com/CatalystCreator back on the 9th of August 2012) I cancelled before the unit was completed and shipped. This is mostly a problem for Clevo 170EM/150EM based laptops which have no way of bypassing the Enduro graphics switching unlike Alienware products which have a hardware switch.
Basically there is something very wrong with this immature technology. Users are finding under utilisation of their cards (for example Battlefield 3 64 person multiplayer fps dips with lower recorded GPU utilisation) when it should be going flat out. Even worse is when the graphical settings are lowered to try and allow for more fps to be pumped out by the GPU the situation does not improve. It is as if the Enduro tech is deciding that the lower workload required at lower resolution or graphical settings means it can lower utilisation further. This means that someone with FPS issues at Ultra settings can drop to Medium settings and not see any improvement in output.

Many owners of systems with 7970M graphics cards are now concerned with AMD's reluctance to comment on the problems that they are just going to try and sweep it under the carpet and move on to the next generation of GPU with the next generation of Enduro, perhaps one that works. No one is exactly sure if the problem is even something that can be overcome with a software/driver or whether it is a hardware issue that the Clevo based laptops are stuck with.
