Would also like some clarification on the 8GB GPU memory recommendation.
I read that to mine Ethereum a DAG file needs to be stored inside of the GPU memory, and that it’s growing in size. It’s expected that by Feb 2021 the 4GB cards wont be big enough anymore (https://investoon.com/tools/dag_size) and also that as it uses more and more of the 4GB available the hashrate slows down.
I also found this thread (https://bitcointalk.org/index.php?topic=3001835.0) where people basically say that 3 years are enough time for Ethereum and other algorithms don’t need as much RAM, so buying 4GB cards even now is absolutely fine. I’d assume Ethereum switched to PoS by then anyway… ^^
So yea, would like a clarification on the 8GB RAM recommendation
