Just uploaded v.15.6 – this was primarily built to re-enable the CPU path, but while looking at that I also realized that I had some pretty egregious spilling code in the KNL path that wasted cycles. In .15.6 this is now fixed. Latest performance:
- on my 7250, with Ubuntu: +/- 1940 H/s
- on a 7220A active card: +/- 1840 H/s.
- 7210 …. still have to check, but not today.
Quite interestingly, at those rates we’re coming back to profitability numbers we haven’t seen in a while: at least if the profit calculators can be belived, at current reduced difficulty 1.9kH is back over 80cents a day. Not as much as during the crazy days (I still remember the $7.50 a day :-/), but way better than the $.20 we’ve seen recently!
With that – happy mining!
