Don't upgrade from a 3060 Ti to a 4060 Ti just because the model number is bigger. Look at what's actually changed, because it's a more mixed picture than the newer-is-better instinct suggests.
The real trade
Used, the 4060 Ti runs $74.71 more than the 3060 Ti on ChipFlip's tracked listings, a 33% premium. That's real money for a card that, per independent testing, doesn't cleanly outperform the older one across the board. In several comparisons the 3060 Ti actually lands a bit ahead in raw rasterized performance at 1440p, with the 4060 Ti's advantage showing up mainly when DLSS 3 frame generation kicks in on supported titles, not as a flat, everywhere-you-look win.
Where the 4060 Ti genuinely pulls ahead
Efficiency and ray tracing. It draws meaningfully less power for similar or better output, and its RT performance and DLSS 3 support matter a lot more if path tracing or heavy ray tracing is genuinely part of your regular gaming diet.
Where the 3060 Ti still holds up
Straightforward 1080p or 1440p rasterized gaming without heavy ray tracing. It's not falling behind here the way the model-year gap might suggest, and if it's meaningfully cheaper, there's no real performance case for skipping it in favor of the newer card.
The takeaway
Upgrade for efficiency and ray tracing specifically, not for the number going from 3000 to 4000. If neither of those really matters to how you game, keeping or buying a 3060 Ti is a legitimately smart, cheaper choice, not a compromise.
