PS4 PRO is using RX480(a bit downlocked though) that came out at the end of 2016,same time as PS4 PRO was released.RX 580 was also released just before XBOX1X and they went with that GPU. So if new AMD 7nm GPU Vega comes out in late 2018/middle 2019 i don't see why they wouldn't go for that. The mid range 7nm Vega should be at least comparable to RX 56 which has 10.5TF but it consumes 210W which is a bit high.A mid range Vega should have about 10-12TF while consuming not more than 150W. We just have to wait until next year when AMD releases 7nm GPU and pay attention to their mid range GPU line-up.I bet we'll get something like RX 670 that has 12TF while consumes less than 180W. That could possibly be GPU for ps5. Just to mention RX 380 had 3.4TF while RX 480 had 5.8TF.That's 70% Teraflop increase in just 1 year.So there is a possibilty that next flagship RX 680 will have above 16TF while RX 670 around 12TF. AMD knows we're gonna need horsepower increase for 4K which is slowly becoming mainstream.In 2 years most midrange cards should be powerful enough to run 4k on medium settings.Plus "double the power(12TF) of XBOX1X would be a good advertisement
).
As far as CPU goes,it doesnt need to be THAT powerful becuse i think next gen will be 4k 30fps not 60fps.7nm AMD Zen 2 design is complete and shipping will start at the end of 2018/beginning 2019.Mobile 7nm custom PS5 with 8 cores(maybe even more?) would still be leaps and bounds better than old Jaguar cores.
Receipt for winning console generation is NOT about having the most powerful console. I think Sony and Cerny know that now and they surely will make console that will be manufactured and sold for 399$.Not too weak but definitely not very powerful.
2019 release
Mobile 7nm cpu @2.0ghz
10TF GPU
16GB GDDR6
But here i am,hoping for 499$ 2020 release with powerful 7nm 8core CPU@3.0ghz,16TF GPU and 24GB GDDR6. That would be a true next gen and we would start seeing some truly groundbreaking graphics,physics,destruction,population,density of open worlds games,better AI.
P.S Sorry for the long wall of text,beginning of next gen excites me,after that i'm all set for next 6 years
