I thought this table was hard to interpretate, because it shows different speeds for the same GPU: fo/Mining_hardware_comparison. With the scarcity of the excellent Radeon 7950 for mining Litecoin, the focus has been shifted to some other good alternative graphics cards. ColaMax (1 visionTek (1 club 3D (1 released. Thanks a lot. What is better for litecoin mining: 1 R9 280X or 2 HD7870. For other brands of R9 280X, you can try 1060MHz or 1080MHz for the core clock speed as a lot of people are getting good hashrates with that setting. Litecoin Mining Hardware Comparison. Radeon R9 280X, which is essentially a rebranded 7970 is another good option for GPU mining.
Voltage: listed beside the voltage is the status of firmware or hardware voltage locking. My Gigabyte cards run completely stable at 1094mV, so if you are using my undervolting method, simply replace the 1081mV that i have recommended for 79mV. This configuration gets me around 700KHash/sec on each card with a low reject ratio.
