 And why would the tdp increase so significantly when the chips get smaller and more efficient. GPU TDP has been stagnant, it's been around ~250 watt for the last 5-6 years for high end cards.

Here are two articles that explain nicely what is industry currently dealing with when it comes to sub-28nm proccess.

As I said earlier, I would expect to see 15TFLOPS GPU around 2018 for the similar price as what's inside PS4 right now, but I'm sceptical if they don't manage to switch to something new in time.

As for RAM, I remember a lot of naysayers on this very forum (always found that funny) saying how 8GB is insane and way too much for next-gen consoles before PS4 and XOne were revealed. While it is too early to predict what is going to be normal in 2018-19, 64GB really does not seem too much, IMO.


Thanks for the links, interesting read. I think silicon will not be replaced by graphene or other technology by the time PS5 comes out. Chips will not hit the node limits by 2020 with the way current ones are being delayed.
