Ah, I see what you mean. Yeah I think it comes from a place of viewing increase in VRAM as relatively low cost and therefore an artificial limitation of sorts used to differentiate between consumer and workstation products (and the respective price disparities).

Which may be true although there are more differences than just VRAM and I assume those market segments have different perceptions of the real value Gamers want it cheaper/faster, institutions want it closer to state of the art, more robust to lengthy workloads (as in year long training sessions), and better support from nvidia. Among other things.
