I'm not sure where this 1080 comparison popped-up from, bu I think it means GTX1080...which would actually be terribly poor performance for next gen system aimed at 4K that is supposed to launch in 2020 and last at least to 2026.
I'm not sure why some people keep talking about "GTX 1080" performance. PS5 and Next XBox will use a much more efficient and advanced technology, which is not ready yet.
Teraflops alone means nothing. Furthermore, hardware in a close environment can produce far better results than the equivalent hardware into a PC.
