First generation Fusion APUs are based on a GPU (R800, Radeon HD 5000 series) that's three generations ahead of the ones in PS360, though it's also fairly stripped down because it's on the same die as the CPU, and there are heat constraints and such... but IIRC the one used in Fusion's going to be comparable to a 5600-series one, so that would handily out-muscle either of the GPUs of the HD Twins, and offer newer features that they don't.
That being said, however, this rumour is likely not true.
