Quantizing 70b models to 4-bit, how much does performance degrade? (alien.top)

The title, pretty much.

I'm wondering whether a 70b model quantized to 4bit would perform better than a 7b/13b/34b model at fp16. Would be great to get some insights from the community.

It's a rule of thumb that yes, higher parameter at low quant beats lower parameter at high quant (or no quant) but take it with a grain of salt as you may still prefer a lower parameter model that's more tuned for the task you prefer.
