Nvidia Pascal GP104-400 GPU photo surfaces and shows GDDR5X Memory

Nvidia Pascal GP104-400 GPU photo surfaces and shows GDDR5X Memory

Yet another PCB photo appeared with on it, a GPU seated. This time it is the  GP104-400-A1 GPU which which would be the 3rd Pascal GPU surfacing, and kind of seems to confirm a 980 Ti successor, the interesting find here is that is has gDDR5X memory tied to it. 

The GPU photo was posted over the weekend at wccftech and indeed is showing the new GDDR5X Memory. First, here's what we've been showing thus far in our tables, the GP104-200-A1 GPU we've already shown last week through a photo from Chiphell, however:
  

NVIDIA GeForce   Possible
name
Pascal Fab Board Date
GTX Titan X >> TBD GP 100 16nm Reference -> AIB TBD
GTX 980Ti >> GTX 1080 Ti GP 104-400 16nm Reference -> AIB June/July
GTX 980 >> GTX 1080 GP 104-200 16nm Reference -> AIB June
GTX 970 >> GTX 1070 GP 104-150 16nm AIB design June
GTX 960 >> GTX 1060 GP 106 16nm AIB design October
GTX 950 >> GTX 1050 GP 106 16nm AIB design October

As you can see there remains to be an indication for a GP 104-400 GPU. Whether that one ends up as GTX 1080 or GTX 1080 Ti remains unanswered, but the photo does confirm it's a revision 400 in existence. It could very well be that the GP104-200-A1 ends up as GeForce GTX 1070 and the GP104-400 GPU as GeForce GTX 1080. Both cards would get 8GB of graphics memory. Both GPUs hold roughly 8 Billion transistors.

The GP 104-400 GPU tied to GDDR5X DRAM memory is interesting as it does confirm that memory is available. GDDR5X is your standard GDDR5 memory however, opposed to delivering 32 byte/access to the memory cells, this is doubled up towards 64 byte/access. And that in theory could double up graphics card memory bandwidth. Early indications according to presentations show numbers with the memory capable of doing up-to 10 to 12 Gbps, and in the future 16 Gbps. So your high-end graphics cards these days hover at say 400 GB/s. With GDDR5X that could increase to 800 maybe 1000 GB/sec and thus these are very significant improvements.

Check the photo, these are unmistakably Micron GDDR5X DRAM ICs.

Looking forward to actual reviews, but all these leaks will (as always) fulfill their purpose of hyping things up. :)

Little too early for my taste.
Sure, we don't know exact details, but overall they've pretty much spilled the beans.

This could turn into a boring launch, unless there is some secret sauce, or unexpected surprise.

It's PS fake. Chip corners are rounded but green print/sticker perfectly rectangular and non shaded.

IMO GP104-150 is X70m for laptops

gp104-400 x80
gp104-200 x70

1500Mhz Core 980-Ti are already +35% or even +40% better than retail version (1075Mhz boost core).

They better bring some fat cookies to the table if they expect people to upgrade.
And how overclockable are those new ships gonna be compared to 9XX serie?
