> The market for prosumer cards with high VRAM and low FLOPS would be negligibly small.

I don't agree. I regularly get VSCode crashing because it ran out of VRAM.

8GB VRAM starts to feel cramped when you have to composite multiple web browsers (aka Electron apps) onto your 4K monitor screen.

nVidia not offering 16GB on consumer level cards is purely a market segmentation strategy and AMD should make them pay for it.
