How powerfull are the next consoles going to be?

It depends if PS4K uses Polaris 36 CU version. Polaris 10 has 232 mm^2 chip size which is close to PS4's 212 mm^2 chip size GPU.

AMD plans for Polaris 10 is affordable R9-290X level GPU (R9-390's current price is $299) i.e. meeting the minimum PC VR GPU standard.

NX, MS and Sony may ride AMD's 14 nm FinFET Polaris wave.

PC owners has Vegas 10 (64 CU Polaris)

Remember

Polaris's 36 CU ~= Hawaii XT's 44 CU ~= Fury Pro's 56 CU

Vegas 10's 64 CU ~= slightly below 2X Polaris 36 CU.

Vegas 10 seems to target Fury Pro Duo (two Fury Nano GPUs in one card).

What part of "we'll see" don't you understand? Stop replying to me. Also, Vegas 10 is a year away.

Why did you get involve in this topic?

@ronvalencia: Ah, thank you. So even if they were willing to up the size of the GPU how would they cool it in the PS4 while maintaining that form factor and cost? AMD GPUs don't have a reputation for being very cool. Has that changed significantly where the GPU could be placed in a small low cost console?

For PS4, Sony effectively used 7970M i.e. the mobile version of desktop 7870. The old 7970M's power consumption is around 100 watts. If the pattern holds true, Sony may again select AMD's best mobile GPU to power PS4K.

Besides Apple's IMac 2015 (with mobile Tonga XT), AMD did not give PC desktop users any mobile grade GCNs i.e. these mobile GCN grades are reserved for embedded, laptop OEMs and Apple (special treatment).

From the paper spec, Polaris 36 CU is 2X over PS4's 18 CU, but it's much faster e.g. beating R9-290X in AMD's own benchmarks.

7970M = 212 mm^2 chip size with ~100 watts.

Polaris 36 CU = 232 mm^2 chip size with ~??? watts. Mobile version would be aiming for 100 watts.

Polaris 40 watts (7870 GE performance level) just replaced my 34 watts 8870M (same design as desktop 7770, 10 CU) on my Samsung ATIV Book 8 laptop i.e. that's about 2.5X performance per watt.

Mobile Tonga XT's chip size is 366 mm^2.

For PS4.5, you need a new GPU with around 250 mm^2 with 100 watts limit.

14nm FinFET mobile Tonga XT 32 CU (GCN gen 3) vs 14 nm FinFET Polaris 36 CU (GCN gen 4).

Tonga XT doesn't meet the minimum for PC VR gaming GPU.

Polaris 36 CU meets the minimum for PC VR gaming GPU.

The Ori and the Blind Forrest dev has confirmed that NX is nothing more than a handheld that connects to your TV. It is drastically weaker than XBox One.
