I think what ever the potential of the Ampere architecture, the performance will be around 10% - 15% improved over current generation.
This is so Nvidia can 'milk' the architecture as much as possible in the coming years. If they are running tests and they realise the they could push up to 60% more performance, they will release this performance in batches over the next generations of cards that will come in the next few years. So, yeah I am excited about the new cards, but Nvidia is always a business, and they won't release the full performance in the first batch, as this would leave them empty handed.
