Hate to break it to you, but if eth profits drop to zero it would still be profitable to mine other coins. I think the only thing that will stop it is if crypto prices as a whole crash again. I'm sure if it no longer becomes profitable to mine eth that a lot of cards will be sold on ebay, but people with efficient setups might just be looking at a 50% cut in their profits as they switch to other coins.I don't understand what you mean.
I don't agree increment model numbers and refresh has disappeared. Each new model was on a one or perhaps 1.5 year cadence for the most part for quite a few generations of cards.
I'm saying that the 40x0 cards release, my guess/speculation anyway, will be longer cycle than normal. As in we probably won't see the 40x0 cards released at the 2021, one year date of this 2020 September release of the 3080 ampere. It wouldn't surprise me if we don't see the 40x0 cards until mid 2022, maybe even late 2022. Ti's and Supers of the Ampere generation could be at any time, and that wouldn't surprise me -- especially if they try to cripple the ETH hash rate as they did on the 3060 to sell more CMP cards. It might mean they will stop making the original 3060TI, 3070, 3080, and 3090 boards all together and move to the new hash limited supers or Ti's for all subsequent releases. Forcing their CMP card sales for those who want to mine.
Then again, the new July EIP 1559 change to the ETH algorithm might really throw all the guess up into the air and where they land nobody knows.
