so asics now don't have a significant increase in speed/MHs or efficiency like x3 or x4 hashrate over the previous gen...rather 20% more hash + 2gb ram? LOL what a joke
year 2023 DAG will be 6gb, gpus can be 1:1 compared to 1:2 in performance and efficiency vs ETH asic (year 2020 model).
it means you can still use ETH asic (year 2020 model) if it has 8gb. but they still used 6gb so they can sell more (year 2023) with 8gb because 6gb are useless by then.
what is an extra 2gb? ..it is nothing in overall manufacturing expense, people can pay the extra 100$ or less? for assurance that in year 2023 that asic can still be used.
