I think IO transfer speeds are more relevant now, an SSD paired with extremely high BW memory will be more important than a large pool of slow memory tied to slow HDAny historical pricing data on memory between those generational periods?

I am curious that since 7nm process has 2.56x power efficiency
Only one pool of DDR4 is absurd for a gaming console. It's way too slow.64GB of DDR4 in a SDK is more than possible. 32GB of GDDR6 in a console is laughable at this point and time.

I think that is quite beliveable they will go HBM2 to compensate the power excess.Today I'm leaning more to the ~9TF rumored PS5. We'll know more about Navi at E3, but we already know that it uses GDDR6 and I suspect that that it will use a 256-bit bus and the 14 Gbps memory variant. I suspect that the rumored CU counts (40) and clock speeds (1.8-2.0 Ghz) are probably close (so a 9-10TF GPU). Which would lead me to believe that the for more teraflops, we'd need a much higher bandwidth (and hence a bigger bus).
I don't see a 384-bit bus showing up in a PS5 (maybe Xbox if there truly are multiple SKU's with a premium one). Too big for a new and expensive process. So I think a PS5 will have 256-bit bus with 16-Gbps GDDR6 to provide the additional bandwidth for the CPU. The teraflop count will be what the power dissipation allows (max being what's in the Radeon 57xx). Maybe the PS5 GPU will have some additional minor features, but I think that the majority of the work going into Navi for PS5 will center around area and power optimizations. While still important, area and power consumption are not as important for consumer GPU's as they are for consoles.
Yeah for some reason I think the 8GB hbm rumour is true
I would bet my left kidney it wont be a single digit Tflop for PS5 regardless of how efficient those Tflops are, if purely for marketing purpose. I think for power dissipation they'd rather go for a bigger form factor and vapor chamber than skimp on Tflops since you can always do shrink revisions with future fabric. Jason from Kotaku also heard about numbers way higher than 8 Tflops for PS5 so there's that.Today I'm leaning more to the ~9TF rumored PS5.

Not talking about the yakuza, but reddit post...Already mentioned above.
What reddit post? Your link is talking about what the Yakuza guy said.Not talking about the yakuza, but reddit post...

Okay, watched the video for a few minutes and there's a reddit post at 10 minutes. If that's what you wanted to talk about, you should have linked to that.
Anyway, yes, it was covered Saturday. Not discussed here as there's a separate thread for churning through the limitless rumours of the internet in this pre-release trolling era where randoms like to make stuff up for no good reason.
I enjoy researching graphics related topics on an academic level and working on my GPU-based Photon Mapping renderer ‘Epicurus‘. I’m especially interested in global illumination algorithms, analyzing the physical properties of various natural optical phenomena and staying updated on new techniques used in the graphics field
