Question. Does the 800mm^2 include HBM?
As Denial says GTX die will be much smaller. GP100 is 610mm^2 and GP102 is 471mm^2. Full size GTX Volta may be more around 560mm^2. Which is not a huge jump from GP102. Vega is rumored around 520mm^2 for reference and the users in here talking about how expensive the Volta cards will be based on die size think Vega will be retailing for $300.

show me the next xx60 card!

But the article is worded like GP100's 610mm2 is just the die only. So I'm not sure.
According to PC Perspective the max interposer size is 830mm2.

Apparently the die mm2 includes the HBM2/Interposer. So the actual die is smaller. Also the tensor units are why FP32 is low given the die size itself. The tensor units most likely won't be on the gaming cards - or will be severely cut down. Along with the FP64.
Edit: I guess I could have appended this to my previous post. Sorry.

Nerdgasmic. I want one with hacked drivers 🤓

So ~15Tflop for GV100, midget high-end GV104 ~ 12Tflop?

Yeah, I was about to say its probably with HBM interposer,..
Im sure normal GTX variant will remain in the same price range 699$, 1080Ti settled to ~700- 750€, just like 980Ti after 1-2months.

The big news I'm getting out of this is that Volta has had a third process switch and it's now again at 16/12nm. Which means it will most likely come for consumer products earlier than the end of Q1 2018, as initially predicted.
The gaming teraflop numbers aren't exactly crazy though, an overclocked 1080Ti will get close to these. That's pretty much a 2GHz 1080Ti. It's not as huge a leap as I imagined it to be, so I'm curious what different things the actual architecture holds. They seem to have gone very wide this time, I wonder if other architectural details are different or this is "just" a wider Pascal.
Interesting times ahead. And yes, that chip is massive.
About the die size, isn't Vega 530-560mm2 and 12.5Tflop? What I'm reading wrong here? Are the tensor parts that much of the die size? It seems like they aren't, considering that the increase of SM from 56-80 seems to be almost proportional to the increase in die size.

Has some more information about architectural changes.
Seems like PRMinister was right - they kind of copied AMD's implementation of thread scheduling although it isn't clear how similar it is to what AMD does. Probably won't find out till closer to launch.

Its hard to conclude anything about GTX line from this GV100 data. Two being completely bifurcated and GV100 carrying significant amount of extra weight. One of few things they do share is:
Volta SM (Streaming Multiprocessor)
New mixed-precision FP16/FP32 Tensor Cores purpose-built for deep learning matrix arithmetic;
Enhanced L1 data cache for higher performance and lower latency;
Streamlined instruction set for simpler decoding and reduced instruction latencies
higher clocks and higher power efficiency.

I'll get excited when the software catches up to the hardware. I've fallen for the hype of hardware too many times, to just sit on it playing console ports. Sounds impressive, but until I see a game that NEEDS it, I'm not impressed. Why buy a V8 if you're only driving to work?

Holy crap it really is 815mm2. And TSMC has made 12FFN exclusivly for Nvidia.
According to JHH: It's at the reticle limit. You cant make a bigger die. Getting one working die per 12'' wafer is - unlikely
