Title: Mining: Using ATI cards compared to dedicated ASIC mining machines Post by: ed1973 on December 19, 2013, 11:04:09 PM I am just a newby and I question myself:
Why do most people use ATI graphic cards to mine bitcoins, instead of using dedicated ASIC mining machines ? I found this link : https://en.bitcoin.it/wiki/Mining_hardware_comparison When I look at: - hash rate (Mhash/s) - price - power consumption I conclude that a dedicated mining machine Xtreme Miners Lion 7.5 Th of $14.500 with a hash rate of 7.500.000 Mhash/s and power consumption of 2250 Watt, is much more efficient then the setup I found on this website : https://en.bitcoin.it/wiki/Mining_rig A PC with Three ATI 6990s cards, total costs $1824 with a hash rate of 1.400 Mhash/s and power consumption of max 950 Watt. I really do not understand, why people invest in ATI cards, while the dedicated mining machine is about 5000x faster and cost about 10x times as much. Can somebody explain this to me ?

Keep in mind, that I am still learning. Title: Re: Mining: Using ATI cards compared to dedicated ASIC mining machines Post by: bitpop on December 20, 2013, 09:07:16 AM They don't, only for litecoin

Title: Re: Mining: Using ATI cards compared to dedicated ASIC mining machines Post by: DrG on December 20, 2013, 01:30:10 PM Pretty much all Bitcoin mining today is all ASIC (a few FPGA). Bitcoin started off using CPU, then went GPU in 2011, FPGA in 2011/2012 and ASIC in 2013.
Litecoin became a strong alt as many other alts failed. It started as CPU mining and is now on the GPU mining cycle. Supposedly ASIC are in the works but given the way it is computed that seems unlikely. |
