As I am not allowed to express my opinion about these specs, I'll just ask:
Is this good or bad?
Compared to PS360: good.
Compared to PS4/720: bad.
The GPU ifself is just 50% better than the Xenos/RSX... it's expected better GPUs in Durango (300% better) and Orbis (500% better).
Of course... that's just GPU specs... no "special sauce" or fixed units that help the overall performance of the system.
