Difference in power usage for ZEC & ETH, 1070ti?

[gt_addict]

Just a quick query for anyone that has possibly experienced mining both coins. Currently my hobby rig (6x1070ti,1x1050ti, Ryzen. 1700x) is using 1000w and getting approx 207mh Eth, 1062mh Pasc, 480hs Xmr.

Would my rig use less electricity if it was mining Zec?

What sparked the question is im currently experimenting with an RX580 and switch from eth to zec and noticed a 50w decrease in power consumption. So just wondering if the same applies to nvidia cards?

Thanks.

Ethash peeks at noticeable less power than equihash on my 1060's (most probably the same for all Pascal cards).
Equihash like more core clock and that apparently cost more power then boosted memory (which benefits ethash).

Thats exactly the opposite of what I have experienced. The equihash (zec) is using less power.

Maybe in the early days of ZEC when mining software were completely unoptimized. It's no longer true, Ethash is so memory bandwidth bound that you can heavily underclock a regular 1070 without affecting Ethereum hash rate. ZEC and other Equihash coins on the other hand, scales pretty well with increased core count and clock speed.

I am in agreement that Ethash is more power efficient than Equihash. I haven't exactly compared wattage on my rigs mining ZEC or ETH but in theory, the need for higher core clock in equihash will draw more power from the GPUs compared to ethhash.

Maybe someone who has actually measured power consumption can chime in.

Anyone?

Well i switched over to zec breifly and noticed a slight drop in power consumption when using ewbf. Dropped 20w mining zec (1005w mining eth/pasc, 985w mining zec). Used cryptocompare calculator and it seems im $50a month better off mining zec

I recently did some tests with my single 1070ti as I was trying to make sure I making the most from it, here’s what I found (btw, mine has Samsung memory ):

GTX 1070 Ti Settings:
Claymore: 55% power, -100 clock, +1000 memory = 34.2 Mh/s, 98w
Fan: 60%, Temp = 62 C

XMR-stak: 70% power, +200 clock, +1000 memory = 788 h/s, 92w
Fan: 65%, Temp = 49 C

EWBF: 80% power, +240 clock, +1000 memory = 560 sol/s, 143w
Fan: 85%, Temp = 58 C


 So for me ETH mining was the most efficient power wise, but I only mine ETH (no dual mining).   Are you really making that much more with dual mining?  I have always found it to be not worth the trouble when you consider the additional power needed, and the fees involved.

The dual mining is just a bonus as i dont get any better stable hashrate just mining Eth and it doesnt use any extra power.

I tweaked the OC settings for EWBF and got power usge down to 935w so each card was getting 4.3sol/w at 65% tdp, +200core +750mem (on average). So definitely better to mine equihash until eth price increases

here is a comparison of hash/power/cost for different gpus on zec and eth

Doesnt have hashrates the same as I have so can’t use it for comparison unfortunately.
