Insider Daily. 80% of developers do not have access to dGPU part yet. Mistercteam explains it all.

Insider: Ok heads up this is a big clue. the sort of thing we are looking for is. four very specialized gfx cores that can only be accessed via the metal xdriver. Full stereo only available after 25/30 to majority. 80% of developers only have low access.

These cores have access to all the 8 core cpu threads if need be. But two of each cpu threads do have a specialist purpose. They also have a boost ability for a special type of graphics code. Not yet seen on pc.

Mistercteam is correct in his findings but is still wrong in Others. The reason things look strange when you measure the silicon. Your looking for a massive dgpu that is just sitting there w2w or 2.5D.. the design is strange.  But I will say nobody has seen the final design aspect. Like i said when I seen the last design a few months back before calibration.  The gfx cores and cpus were siting next to the main soc silicon. I say keep digging. Just dont expect any thing less then 1.31tf or 5.31tf

the last thing do not think of this dgpu as one big gfx core it doesn't have to be with 8/10mb of specialized esram attached.. with the guest mmc it should help.. host/guest :)

Also ms have green light now. They could come early. But it will all make seens 29/30 no matter. And tier4 enabled.

Insider: Like I said the sony 3$ attack dogs are on to this blog.. stay strong. And the sony kind have to all ways attack personal aspects of people don't player there games
This magical 30% of power there   console "had" .its a real shame cant be transferred to logic and reason in there brains.
Sony had to sell there head office to fund ps4 development and marketing.
Parasite is correct in the change in gpu. But its not just a 9000 seires its a combination. And its not physically a single chip. :)

Mono is only access Main SOC
Stereo is when they can access Both gpuSOC  + MainSOC
Stereo will be enabled after 25/30
80% still using mono driver

It is why (highly possibility) that why BF4 & Ghost & Wdogs still have to presented on PC specced X1 devkit
as they waiting stereo driver to be enabled,  by the time it is enabled, BF4 ad other demanding games
can use full power of X1. and infact better on some part than the PC version as it was tier4 (later on i will explain)
also inline with parasite, about BF4 info

Ok so this is a confirm that per CPU on dGPU can have more than 2 thread per core, it is like i said SMT4 + SMT2 (for GFx) totalling 48 operation (my explanation is to simplyfy things, basically he explain cpu on dgpu SOC not cpu on mainSOC)

so with this info  probably 2.5D , the smaller dies will be 22/20nm remember 22/20nm is 2 times denser than 28nm
even if you see it small it is certainly 2 times the size of it at 28nm , so 175mm^2 on 22nm is about 350mm^2 on 28nm

the dGPU is cosist of 2x smaller wafer (see diagram below)
each smaller wafer in 22nm hold: 4CPU core power ISA + 1152 ALU
so dGPU = 2x4CPU + 2x1152 ALU
the TF = 2304 x 2 x 0.8 = 3.6 TF , plus MainSOC will be 4.8 TF (inline with parasite)

The dGPU will have 9xxx tech and customized, the MainSOC will be 7xxx or 8xxxx
(not a single GPU, dGPU is splitted)
on reality the GPU series wont be from same PC/mobile verision as it will be highly customized
the reality is dGPU is supposed to be Tier4 (GCN 2.0+)

*) remember latest GCN 1.1 are tier 2, with VI is supposed to be tier2 or tier3, tier 3 will have new function probably will be disclosed for DX 11.5, probably Tier4 are new advanced tech that wont be available on PC or tier3 yet, basically dGPU will be new architecture.

insider: the last thing do not think of this dgpu as one big gfx core it doesn't have to be with 8/10mb of specialized esram attached
i agree so dGPU will use eSRAM through guest/host MMU the other 8/10MB is certainly for use on dGPU but from 47MB
(side note :7970 use 12MB SRAM/eSRAM)

*) 22nm SOI is about 2 times denser than 28nm
now for the diagram if we believe it will be 2.5D and remember this is speculation .
