While the narrower bus hurts at higher resolutions, a wider bus with the same amount of memory wouldn't help the situation when it runs out of VRAM. In that case, it would be limited by the PCIe link to the host. Since the PCIe link is much slower than even the 128-bit GDDR6 interface, relying on it is not a good solution.IMO Nvidia are just embarassed about the whole thing.
It was a knee-jerk reaction to reviewers and customers destroying the 4060 Ti's lack of VRAM. The problem with the 4060 Ti's performance isn't just a lack of VRAM though, it's the lack of bandwidth to feed that VRAM.
Look at the 3060 Ti which also has just 8GB VRAM - it's performance doesn't nosedive as badly as the 4060 Ti does when approaching or exceeding the VRAM buffer, because it's on a 256-bit bus with twice the bandwidth and can do the undesirable data juggling twice as fast. Both cards stutter where 12GB cards don't, but the stuttering on an 8GB 3060 Ti or 3070 is far less intrusive and settles down faster too.
