Leaks from some developers that are working the first round of PS5 games say their Sony supplied PC Dev kits have around 20TF. Those are not true console dev kits but mock PC dev kits made to give an early approximation of the real deal
First that these mock PC Dev kits usually have >2x the performance of the consoles' final hardware. It's the first time I've heard of such a thing. Dev kits usually do have 2x the RAM because of debugging, so perhaps he mixed things up?
So a Vega 56 crossfire rig, why not just a Vega 64 for better single gpu scaling since the "supposed" final spec is way less than 13.7 TF anyway?Posted June 20, 2018

Because your devkit needs to run early dev code, on early APIs at the performance level of your final product and your final product is based on a chipset architecture that likely includes new technologies, to approximate that without the benefit of those technologies, which could enhance bus performance, reduce bandwidth and/or accelerate other features, you sometimes to go crazy high.
I superlove this whole idea. I want to dream as a child again, I want to be truly excited about next gen consoles, I want to feel these emotions.I already did the math on that one. 20 TF Cell ubercomputer would fit onto the same silicon as an RTX2080 (going by transistor counts). Some still try to resist the One True Faith, but they'll come around when Cell2 (codenamed "Neutrophil") is used in PS5, the world's first real-time raytracing console, using techniques inspired by the world's greatest ever computer, the Amiga, and how it handled 3D in realtime (postage-stamp sized resolution...).
I agree that anything other than 10TF would be underwhelming. That would influence my preferred platform for sure.So a Vega 56 crossfire rig, why not just a Vega 64 for better single gpu scaling since the "supposed" final spec is way less than 13.7 TF anyway?
8-10 TF PS5 is gonna be highly disappointing, might skip it at launch if that's the case although I doubt that leak's authenticity.
There are sound reasons, but are they usual on GPUs for high-performance consoles, when the architecture is actually similar to the final one (Vega <-> Navi)? I remember reports on Wii U PC devkits having HD4850 graphics cards, but that console ended up being a low-performance device.
There's also the fact that there's no AMD GPU capable of reaching 20 TFLOPs or anything near that, nor there will be until late 2018 with 7nm Vega 20, so what could be in said devkit? Two Vega 56 that will scale up terribly and a Liquid Cooled Vega 64 would have better performance?
Perhaps one day this could happen, realistically, if programming for Cell was trivial for all game developers (which perhaps one day it will be) I think this would have been a potential good timeline.I already did the math on that one. 20 TF Cell ubercomputer would fit onto the same silicon as an RTX2080 (going by transistor counts).

Edit: There are plenty of funny numbers to be had with this idea. 80 Cell BBEs would fit on the silicon. Assuming no trouble connecting them up, you'd have 80x the attained ~200 GB/s SPE data access across the EIB, so 16 TB/s internal bandwidth. 160 MBs of SRAM local storage on SPEs and another 40 MBs for the PPEs' cache.

Heh yea A but B i had pondered about for some time. Had Sony kept with Cell, PS5 would be their 3rd generation and possibly have BC all the way back to PS3 titles to boot.Cell was before it's time. It hit consume hardware before highly parallelised multi-threaded code was prevalent in gaming and Cell relied on these techniques to shine. Had Sony stuck with Cell for PS4 it a) would still have been he wrong choice but b) would have been a whole lot less of an issue because parallelised code was something all devs had learnt during the seventh generation of consoles.

There was a dramatic shift it would appear around that time. Was mobile such a large threat to the industry such that MS went TV TV and PS wanted to go with easier to develop hardware ?Cell was 100% a good bet in 2004 when Sony committed to it for PS3 but equally was 100% a bad bet in 2010 when Sony likely committed to PS4 hardware. Everything is obvious with the benefit for hindsight.
