If the other rumor is true, and the GPU is integrated on the CPU, they might be using an older GPU because it was the best option when they began the work needed to design an integrated chip ...

And in an intergrated chip you want as low power and effeciant use of space possible meaning a more modern achitecure is a must. And would make bassing it off an older desktop GPU even less likely as you would basically need to change everything about it to get it to work well on a SoC. AMDs Trinity GPU core would be the best bet bassed on the 7000 series it is already designed for a SoC and has a groundbreaking CPU/GPU linking system that promises much better performance and would be perfect for SoC bassed console, again that makes the IGN rumour look suspect.
