This is bad information for miners on processors, because now Bitmain can make ASICs for any coins that need to be mined on processors. Home mining will unfortunately die.
How many SG2042 processors are there in one ASIC?
I just saw 6 processors on 1 board.
It's not an ASIC! It's a cluster of CPUs in one box and it overcomes the final barrier for CPU mining: scaling.
Bitmain disn't do anything special, they're just regular off the shelf CPUs, much simpler that designing and building an ASIC.
If CPU mining appliances catch on (there's another thread about a Pi cluster) CPUs will be better able to compete against GPUs.
