Was to be expected that it had some mix of different architectures, The GPUs of PS4, XBO, X360 and PS3 all were built in such a way.
And the PS4 Pro has some features from the RDNA architecture as well, if I'm not mistaken.
But it's still a bit weird that they mixed both aechitectures instead of going with a full RDNA2 chip. We'll see if the rumor/leak is true or not.
Please excuse my bad English.
