I hear this logic , but those big farms will all switch equihash anyways when POS happens , might as well get the cheapest cards.
two 570s can do the work of 1 1070ti for a lower price
$225 per card
never understood why people buy cards that cost near $600
Efficiency and rig density.
A pair of 570 can match a single 1070 ti on hashrate, but at what cost in power usage? 50% worse? 30% worse?
To match the efficiency of my 1070 ti rigs, they would have to manage 230 sol/s at UNDER 55 WATTS power usage - then factor in "more power used per GPU by system overhead" and they're have to get into the 45-50 watt range.
The 230 sol figure is trivial for a RX 470/480/570/580 card - but that 55 watt figure? *ROFLMAOSC*
RX cards CRUSH Nvidia at current pricing for ETH and spinoffs (except possibly the 1060 that they only "beat"), but that's not the case on many other algos - and do keep in mind that ETH *IS* making progress towards the end of Proof of Work.
Also, I'm not seeing 570 cards at $225 - $239 AND UP last time I checked and availability seems to be dropping again while price is starting to rise again - though still pretty close to half the price of a 1070 ti.
It's also why some folks prefer the 1080 ti over the 1070 ti - efficiency there is close and the rig density makes up for the slightly worse hash/$ and hash/watt figures.
I do have to wonder what the Volta Nvidia generation is going to look like - based on the figures out of the Titan V, I'm guessing 5+ efficiency at even PUSHED hashrate figures might happen, with some potential for "the most efficient model" touching 6.
Remember, you saw that prediciton here from me FIRST!
