Well, that part of it may not be entirely accurate (some would still consider it to be high-end), but the specs sure are.
78xx series is not enthusiast level
They aren't... an enthusiast product would be the 7970 (Ghz) card. Compare the specs in the OP with this, and there you go. PS4's GPU is slightly stronger than the 7850 on the PC, which is a mid-range card in every sense of the word.I was referring to the specs of the GPU, not if the claim that it was an "enthusiast GPU" was accurate.
