Yesterday Lisa Su from AMD announced that big Navi is going to be announced next month (and there have been far too many announcements about announcements). But meanwhile, in Asia, there's always a guy that has something to show. And as it turns out, that would be a photo of big Navi.

The photo shows the backside' of the allegedly a Big Navi prototype PCB. You can see that Big Navi indeed is big as well as eight memory SMT traces with paper labels "Typical XT ASIC" references for a "16 Gb Samsung GDDR6 memory." 

Also, excellent cooler :) (again prototype sample)

That's a 256-bit memory interface then. The chip thus should be paired with 16 GB of GDDR6 memory; we don't think AMD would be silly enough to go with 8GB. It's an engineering sample of some kinds, hence all the paper labels and such. Well, we'll see it at the October 28 launch.

Here is an alleged photo of AMD Radeon Big Navi Radeon RX 6000
