Powercolor R9 270X PCS+ 2GB Graphics Card Review

Scrypt Hashing (Litecoin, Worldcoin, Feathercoin, etc..)

In response to growing enthusiasm to the world of cryptocurrencies we have started to benchmark graphics card for their hashing power. While Bitcoin mining is pointless and unprofitable on consumer hardware, Scrypt mining can still be very profitable due to the absence of Scrypt ASIC miners. We use CGMiner for AMD cards, and CUDA miner for Nvidia cards to benchmark their Scrypt Hashing performance. Below you can see a summary of our configurations for each of the GPUs we have tested so far. We will be adding more GPUs in the future, and will probably do a featured article on it, so the list will expand. In the meantime you can see more Scrypt-hash results here.

HD 7870/ R9 270X/ R9 270 (Pitcairn) – “–shaders 1280 –thread-concurrency=16000 –intensity=19 -g 1 -w 256”

HD 7970/ HD 7970 GHz Edition/ R9 280X (Tahiti) – “–shaders 2048 –thread-concurrency=24000 –intensity=13 -g 1 -w 256”
