HBM2 package size = 7.75 mm x 11.87 mm
... Looks like its between 530-560 sq mm . Right in between GP102 and GP100

architektura bude 8K ready, cip urcite nie.. uz len ta virtualna pamat...

"Vega is designed to handle up to 11 polygons per clock with 4 geometry engines."

The architecture was completely revamped:
- New command processor and ACEs to balance better the workloads.
- New geometry engine and rasterizer, 2.75x better than Fiji at same clocks.
- Rasterizer uses an on-chip cache instead of the vRAM, less power, better culling.
- New CUs, more IPC, more frequency, 2xfp16, 4xInt8, Vega will compete with 10000$ gpus.
- New pixel engine, new ROPs connected to L2, improvements with deferred shading.
- Primitive shaders substitute geometry and vertex shaders. The big question is if the drivers do it or progammers have to code their applications to use them.
- New memory controller, connected to VRAM, high bandwidth cache, L2 ,etc.

In some respects AMD has not significantly altered their shader core since the launch of the very first GCN parts 5 years ago. Various iterations of GCN have added new instructions and features, but the shader core has remained largely constant, and IPC within the shader core itself hasn’t changed too much. Even Polaris (GCN 4) followed this trend, sharing its whole ISA with GCN 1.2.

With Vega, this is changing. By just how much remains to be seen, but it is clear that even with what we see today, AMD is already undertaking the biggest change to their shader core since the launch of GCN.
