A little would probably go a long way I imagine. I mean all the cache that takes up tons of die space are on the chiplets. The GCD is all logic... even if they decided to go up to 350mm or so the amount of extra horsepower would be impressive. I don't know if they will... heck this might be it for this gen. I think of it like early zen. As ground breaking as zen 1 was, it was the follow ups that took the idea and ran with it. I think this gen they where probably conservative. Make sure it works they couldn't afford to have a generation fall on its face. Knowing how Su dealt with Zen though I'm sure they already have the next gen well on the way... cause they probably are going to use the exact same cache chiplets. I wouldn't be shocked if they already had very early engineering bits for the next gen.I am really thinking this time we are going to see little bigger 7950xt. They can do a lot with the refresh. The rumors of higher core count navi might be bigger chip. I mean GCD is only 300mm so so much to work with there. They can have a big refresh even before RDNA 4.
