One possible use case for heterogeneous CPUs that comes to mind is in laptops the same way AMD Switchable Graphics is used now: to save power when you don't need the performance.
However, I'm not sure if any energy efficiency benefits of this solution wouldn't be offset by the increased software and hardware complexity (which costs both money and battery power). If anything, it might be easier and cheaper for AMD to pair up its high-performance ("Steamroller") x86 cores with low-power ("Jaguar") ones instead.
