Yes, there is a logarithmically-bound (or exponential if you're viewing it from another angle) falloff in the information lost in quantization. This comes from the non-uniform "value" of different weights. We can try to get around them with different methods, but at the end of the day, some parameters just hurt more to squeeze. What is insane though is how far we've taken it. I remember when INT8 from NVIDIA seemed like a nigh-pipedream!
