I was looking at the antminer S3 page, at it says it is 355 watts with a 225 mhz frequency.....Is it possible that that S3 just has a lot of undervolted S1 chips? Anyone with a S3 can comment on this? Or is this a nm change?
That's basically what the S2 was. The S3 actually has fewer chips than a S1, it is in fact a die shrink, and the chips are much faster (per chip).
