I was looking into buying a Radeon 7950 card, and while searching Google for its hash rate, I found some threads here on bitcointalk saying like 700
Mhash, ~660
MH/sec, and at least 550
MH.
Then I went to a few different sellers and they say the same card works on 650
khs and 600
Kh/s, using
K, not
M.
The only difference I could find is that
M comes with a capital
H, while
K came with a lower
h.
After some search I only found this on the Wiki:
Mhash/s = millions hashes per second (raw speed performance; may not be very energy efficient with some models).
I thought M meant Mega, as K would mean Kilo, now I am utterly confused... Could someone help?
If the sellers are using kh/s, they're referring to litecoin mining. Litecoin hash rates are much lower than Bitcoin hash rates.
Ignore capitalization in general, all sellers and most websites are quite careless with capitalization when it comes to KH/MH/GH/TH/PH.
K = 1,000 hashes/sec
M = 1,000,000 hashes/sec
G = 1,000,000,000 hashes/sec
T = 1,000,000,000,000 hashes/sec
P = 1,000,000,000,000,000 hashes/sec
