For me it's not really over until it's finally over, it's been a long time since I've been hearing about the dead of GPU mining most especially on Ethereum network but it never happened, same way people believe that Bitcoin will die lol, if ETH is out of PoW then we have other coins as well
Well as much as gpu companies pretend they do not like miners.
They do.
So they have an interest in coin development.
To me Amd has a real interest if they combine an amd cpu and an amd gpu as the only way to mine AMDCPUGPU coin algo.
I would think it would work well.
AMD-DUAL-MINER-ALGO seems like something looking to be invented.
