Nvidia wont be able to keep rtx 6080 at low vram simply coz we will have if not next gen consoles launched then at least their leaked or official specs, with that no1 will be spending 1200-1500usd for 6080 with anything less than 24gigs of vram while keeping in the back of their head new xbox and ps6 will have at least 24gigs.
Last gen ps4/xbox one had 8gigs so we kinda knew already in 2016 to not get the 3gigs 1060 or 4gigs 470/480 if we wanted to keep those cards longer than 2-3years aka not have to replace them right at next gpu family launch.
This gen same thing happened and at least concious customers knew right from the get go that if series x and ps5 got 16gigs, u gonna need at least 12gigs to keep things comfortable(once again rip 3060ti and 3070 owners, those cards are cooked nowadays, not only owners are forced to replace them even before console gen is over- they will get very lil on 2ndhand market coz next owner wont pay much for 8gigs used gpu anyways- checked US prices and its around 300usd for used 3070, only 50usd more from used 3060 yet msrp launch price was 500$ vs 330$(which made sense coz if not vram constrained 3070 is exactly 50% faster on avg).
TLDR: If u spent 500$ on ur 3070 in late 2020/early 2021 (it was 2nd wave of cryptoboom so who knows, chance is u had to pay way above msrp back then), u get doublefucked, on one side u gotta replace it earlier even tho it still has decent performance, just coz of small vram pool, and on the other when u gonna sell it u gonna get way less for the very reason new owner wont pay much for ur old 3070 simply coz it has obvious flaw of 8gigs vram pool.
