It doesn't make the 1630 any better, it makes them all sh*t. I'm not sure how else to put that one for you. They all suck, they all have issues and you shouldn't buy any of them at the current asking prices.
Don‘t disagree with you on the ‚not buying‘ part -the 6500XT / 6400 series was a big disappointment for me.
Still, at least they had a justifiable use case. Someone with an Intel Core 11th or 12th gen non F CPU who wanted something cheap that allowed for decent gaming at the time the card was released got it for less than a 1050Ti and did not make a bad purchase compared to the alternatives. On top of that, it did drive prices for cards like a 1050Ti or 1650 down by a good bit.
The 1630 otoh does not have any use case where there isn‘t an objectively better alternative. I think this is the issue some are taking here - both are not equally bad, the 1630 is - all things considered - far, far worse.
But yes, right now with falling prices neither should be purchased.
