why do both types on mining in a single device? On a single chip at that? is it really practical to design two complex slgorithms in a single chip, instead of producing a sha256-miner and a scrypt-miner?
I don't know if it's
practical per se - but it's been done before at 40nm, by essentially the same company; Gridseed GC3355. I can only imagine it was lucrative for them, at least.
