Maybe even 32GB if they use newer ICs.
More explanation (and my source of the tip): https://www.pcgamer.com/hardware/graphics-cards/shipping-document-suggests-that-a-24-gb-version-of-intels-arc-b580-graphics-card-could-be-heading-to-market-though-not-for-gaming/
Would be awesome if true, and if it's affordable. Screw Nvidia (and, inexplicably, AMD) for their VRAM gouging.
Almost certainly not. The A770 is built like an “upper midrange” GPU while the B580 is a smaller die.
If there’s ever an B770 or whatever, maybe consider it.
If you’re using them for running like coder llms though, that’s a different story.
