Its even sadder that AMD/Intel have failed to take advantage of the price gouging. They could have released affordable 32GB-48GB cards with (afaik) no silicon changes.
The 7900 XTX is still somewhat reasonable where you can get it to work.
And the iGPUs are still pretty small.
We will see how Meteor Lake and Battlemage shake out, but I don't like the delay rumors.
If they intend to release an AI card, I bet they'll charge through the nose for it, just like Nvidia does.
But what they can do is double up the GDDR chips (which is what the 48GB pro cards do), kinda like running 2 DIMMS per channel on desktops. This requires a somewhat more expensive PCB and support from the memory controller, but AMD already supports this for sure, and I would be shocked if the Intel A770 die can't do it.
