Title: Newbie question - What is the conversion factor to go from GH/s to MHash/sec? Post by: Jordz on December 30, 2012, 03:26:27 AM As subject line above read, looking at some units which are rated at GH/s and would like to know what they work out in the more popular MHash/sec.
If they are not measurements of the same output I'd appreciate an explanation of that GH/s is. Thanks in advance (again...) Title: Re: Newbie question - What is the conversion factor to go from GH/s to MHash/sec? Post by: drakahn on December 30, 2012, 03:28:59 AM k= Kilo = 1000
M = Mega = k*1000 = 1000000 G = Giga = M*1000 = 1000000000 Title: Re: Newbie question - What is the conversion factor to go from GH/s to MHash/sec? Post by: Inaba on December 30, 2012, 03:30:37 AM Move the decimal place over 3 spots to convert.

Post by: Stephen Gornick on December 30, 2012, 04:10:19 AM As subject line above read, looking at some units which are rated at GH/s and would like to know what they work out in the more popular MHash/sec. All GPUs are under 1,000 Mhash/s (for bitcoin mining) so the unit for describing their performance is in Mhash/s. There are FPGA units which perform at better than 1,000 Mhash/s so their performance might be rated in terms of Ghash/s. 1 Ghash/s = 1,000 Mhash/s. ASICs also are above 1,000 Mhash/s (well above) so they too are rated in terms of Ghash/s as well. Now this is just for Bitcoin mining. Other alternative crypto currencies might use a different algorithm and thus a card that performs a certain level for Bitcoin mining can have a completely different rating for the alt chain mining. Litecoin, for instance, uses the Scrypt algorithm. So an AMD 5970 that might do 700 Mhash/s when mining Bitcoin might do under Title: Re: Newbie question - What is the conversion factor to go from GH/s to MHash/sec?

The difference would be on a per-model basis versus there being a simple X:Y ratio for comparing how one model might perform versus another. This is correct, except in actuality, a 1Gh/s Bitcoin miner will do around 1Mh/s in Litecoin Title: Re: Newbie question - What is the conversion factor to go from GH/s to MHash/sec? Post by: dree12 on December 30, 2012, 03:30:57 PM The units are GHz ⋅ (2 SHA256) for Gh/s in a Bitcoin context. It effectively means one billion Bitcoin hashes per second. Because MHz ⋅ (2 SHA256) is exactly 1000th of that, the conversion factor is 1000.
