News Maxsun registers several Intel Arc B580 24GB models with the EEC

For gaming,12GB seems like plenty for the B580.
100% agree. 24GB for a card like this is just a waste of memory (for gaming, like you said). And anyone out there needing 24GB for rendering/workstation purposes probably needs a much beefier card if they need 24GB. Maybe, if this card was on a 384-bit board and had a lot more shaders, cores, and CU's plus higher power delivery, it might be worth it. But that's what I imagine would be a B780 (which may never exist).
