Hash Rate variance (BTC vs FTC/LTC)
-
Very confusing. I’ve been searching several different forums for this answer and have come up with nothing. So I thought creating a new topic for this would be better in the case that I’m not the only one without an answer ;).
Does anyone understand why there is a VERY LARGE variance between the hash rates for mining bitcoins versus feathercoins?
For example the HD7970 card is rated to around 680 MH/s. When the same card is used for feathercoins the hash rate is a very small 680 KH/s. That’s about 1320 MH/s less!!
Maybe the answer is the difference in the algorithm used? (Did I just answer my own question lol?)

It’s the difference in the cypto algorithm. Feathercoin is a scrypt based coin, where bitcoin is sha256. For any of the Scrypt based - the hash rate will be in kh/s instead of mh/s.
1gh/s = 1mh/s, etc
Hope this helps!

haha, guess that was the right answer.
Thanks for the feedback!

Yup, you’ve pretty much hit the nail on the head:
“Scrypt hashing speed is estimated to be 1000 times slower than SHA-256.”Scrypt mining (FTC/LTC) also puts a tad more strain onto hardware than SHA-256 mining (BTC) does.
