I think that has the possibility to make it worse honestly. It’s not like the contents of the cache is duplicated. Instead it’s split across a ccx boundary and if the data is in the wrong cache you’ll be hit. Now clever thread management can help avoid this but so far the 9xxx series has shown terrible thread affinity choices with many existing games and apps. I’ll wait and see how the 3D cache helps here.

AMD claims that the 9000X3D series is the product that will provide the game performance increase expected by gamers for a new product generation.

Of course, that remains to be seen, but it is plausible.

Long term as games start using AVX512 I expect the 9000 series will be seen as a big step up against previous generations. One of those "fine wine" things.

That doesn't matter now. Gamers will vote with their dollar, and they are fickle.
