AMD VEGA Die-shot Photo
Well, GPU shot really. Check it out, I checked with AMD if this is a real photo and not a fakes one. It is the real thing though. The VEGA shot shows a thing or two, you can count the 8 blocks that gold the 64 GCN units x 8 NCU units = 512 times eight blocks is 4096 shader processors.
At the bottom the two blocks are the HMB2 stacks, two of them and yes that is 8 GB in total, have a peek. It's rumored to be 500 mm2.

This was shown to be a marketing slide mockup and not a real die shot.

Yeah but It is one of the nicest ways I have seen die info represented for a CPU or GPU. Kind of neat to superimpose it over the actual chip(not just the die).

HBM2 dimensions: 11.87 * 7.75 mm
That taken converted to pixels and reverse pixeling of GPU die makes it 25.17 * 19.57 mm.
So ~493mm^2 ... Comparing to Fiji ~596mm^2 ... Hmm, Kind of Big.
With Ryzen AMD puts 4.8B transistors into ares of ~195mm^2. That could place Vega around 12.1B transistors. That's good 36% more than Fiji.
Where are they? What are those things I do not see on image? Even IMC should save transistors due to using 2*HBM2 instead of 4*HBM1.
Or did AMD decided to use "dead die" and has "empty space" (just matter not actual transistors) in between certain parts to reduce current leakage, improve cooling and achievable frequency?

This seems to happen with Threadripper.

Curious how does DEAD DIE work in terms of an insulator? It acts like an internal heatsink passing thermal waste / energy out to lid then to the heat sinks for dissipation?
