I guess that could be depending on the producer of those vram chips themselves. If 8 GB is the standard size, then a 12 GB design would be likely more expensive to produce. 24 GB cards could be both out of 2x 12 GB or simply 3x 8 GB, so if you just order a buttload of 8 GB you’d save quite a bit of money.
Hmm, I see. I imagine there might be an engineering reason too. Maybe there’s some advantage to only ever halving/doubling memory for a given chip?
