Is it the usual memory divided by two so only 16GB per chip? ("Only" lol). Would be nice if they solved the non-shared memory issue, but my assumption is they haven't.

I shudder at the potential cost.

Infinity Fabric on a GPU....
Many assumed that would happen at some point.
Got me thinking whether NV would go the dual GPU route again too given that RT has caused a slowdown in raw FPS increase this generation. Would be a good time to revive SLI :).

Looks quite impressive albeit as pro cards.

When I saw the info this morning apple the Apple and 28 cores I did wonder why not AMD CPU, although would have to be 32 cores.

The Mi50 and Mi60 You a which are the same as this VEGA duo already had infinity fabric.

This is AMD's version of NVLink. This just provides faster data transfer for Compute applications.

Finally IF connecting two GPUs.

Now that we've seen this, I'd be surprised if by mid 2020 we don't see a bunch of multi GPU in the consumer space from AMD.

It just makes sense, for the same reason it does on the CPU side. More smaller dies = better yields = lower costs and better bins = higher performance, competitive advantage, and lower cost to consumers.

As bigger Navi is obviously coming, and 'next gen' next year I highly doubt Vega 20 Duo gets a consumer launch.

Question is, do they wait for Next Gen, or do it with Navi?

As I've said before, IMO the driver side of things making this work and getting software to treat it like a single GPU really shouldn't be a big deal at all, it was about scaling IF to the bandwidth and latency, over longer traces that are needed for graphics. As they now appear to have that solved finally, I think the rest is a fait accompli.

Also wonder if this now means that, per old rumours, PS5 and XBN will be multi GPU.

You HIGHLY underestimate the challenges of mGPU. This works because it's dedicated to compute tasks. Both AMD & Nvidia already off-loaded mGPU support to game developers going forward, and I don't see that changing.
