I know about Jasminer and Innosilicon A10pro, both 5GB asics
Is there more?
If I remember correctly, the Bitmain E9 have 6Gb (and probably hundreds of them mining right now)
I'll try (not a promise haha) to make the math of the exacly moment ETH hit 5GB dag size and compare with the drop in hashrate, we can have some clue
I confess I'm very curious to know about the percentage of Asics in the network
