The GDDR6 chips seem to be a brand new batch. Normally the branding is parallel to the long edge. It's parallel to the short edge in the picture.
Nvm figured it out. The GDDR6 chips are see through. This is a shot from an unreleased CG trailer.

I've got another interesting disclosure!
The new consoles can support a new shader stage commonly known as "mesh shaders". The major differences listed between the console implementations and current PC hardware are as follows:
The new consoles don't natively support 'task' shaders. Task shaders can be emulated with indirect dispatch and a compute shader. A possible reason for omission in hardware support is that console hardware designers aren't convinced if there's any significant gains to be had in performance with a native implementation.
The console implementations of mesh shaders can support transform feedbacks/streamout where this isn't possible current PC hardware. Mesh shaders in conjunction with global ordered append which is another IHV specific hardware feature makes it trivial for the consoles to be compatible with vertex/geometry/tessellation shaders as seen in the traditional graphics pipeline. Current PC hardware implementation breaks this compatibility with shaders in the traditional graphics pipeline.

Cool. It can't be much wider than what they've shown. If the SOC width is just under 2.3cm then you maybe fit in just over another SOC's width.
Two separate memory pools?
10GB @ 556 GB/s, 6GB @ 336 GB/sAbsoluteBeginner

Knew 560GB/s total is too little for 12TF chip.Two separate memory pools?
Two separate memory pools?
same pool
different regions have different speeds. I assume this will be handled at the page allocation level
