They've had the consoles for yonks now, it doesn't seem to have inflated their bank balance any.
They haven't gone bankrupt with them not having consoles could probably have happened by now. Bulldozer was a really terrible decision for them.
There is also something else people have missed here - have you noticed how the consoles share many of the features of their desktop GPUs quite early on?? The PS4 is the same uarch as AMD Hawaii and even has 8 ACEs too.
I would argue that hints AMD is using its console contracts to help fund some of their GPU R and D too.
