Re: 1GH/s, 20w, $700 (was $500) — Butterflylabs, is it for real? (Part 2)
I just ran some numbers for Inaba's Single @ https://eclipsemc.com/mw.php?key=196e69b1afe10927460b22a8de1c0d:
3:23pm CST: 65612 shares
12:08am CST: 70949 shares (8h45m later)
So the average hashrate during that 8h45m period was:
70949-65612 = 5337 shares in 31500 seconds (8h45m)
5337 shares * 2^32 hashes/share is 2.29e13 hashes
2.29e13 hashes / 31500s = 727Mhps
Not too bad, but still 13% lower than the advertised specs of 832Mhps.
