SAPPHIRE has announced its new cryptocurrency mining specific GPUs, which are coming in a new 'Mining Edition' set of cards with both 4GB and 8GB versions of AMD's Radeon RX 400 and 500 series cards. Ethereum mining is blowing up right now, and I have been all over it building a 41 GPU setup on 10 systems mining 1GH/s.
SAPPHIRE has announced 5 new Mining Edition cards, with British pound pricing from pre-orders on OverclockersUK:
- Sapphire Radeon RX 470 Mining Edition 8GB (Samsung)-£300 ($385)
- Sapphire Radeon RX 470 Mining Edition 8GB-£290 ($372)
- Sapphire Radeon RX 470 Mining Edition 4GB (Samsung)-£260 ($333)
- Sapphire Radeon RX 470 Mining Edition 4GB-£249 ($319)
- Sapphire Radeon RX 560 Mining Edition 4GB-£170 ($218)
All of the Radeon RX 470 versions of SAPPHIRE's new Mining Edition cards don't have any display outputs, but the SAPPHIRE Radeon RX 560 Mining Edition 4GB does feature 1 x DVI port. SAPPHIRE is offering two of its Mining Edition cards with Samsung-made GDDR5 with options for either 4GB or 8GB with Samsung DRAM.
On the SAPPHIRE Radeon RX 470 Mining Edition with 8GB of Samsung GDDR5, you should be mining Ethereum at 25-28MH/s versus 24-27MH/s on the Elpida chips. I'm sure you could also manually overclock the GDDR5 on the cards as well, on top of dropping the power draw and GPU clocks for optimum mining.
SAPPHIRE provides a 1-year warranty on the Mining Edition cards, which is something I'd point to the Furmark level stress on the card 24/7. Another thing to consider is that with no display outputs, these cards are useful only for mining. So the second hand market will be next to nothing on used mining cards, compared to graphics cards that can be used for both, and include much longer warranty than 1-year.
