CryptoCurrency Mining with GPUs *spawn*

Oh I see. If I believe this : http://blog.kraken.com/post/152392567797/zcash-zec-coming-soon-to-kraken you can do that on Kraken (or I misunderstand your need, which is possible ) Well, I mean you don't have to convert them to bitcoin or eth it seems.

 

BTW, mining use only compute units right ? No rops, tmu, are involved in this, right ?

 

I will look into that thx!

Yep compute only, the rest of the GPU is worthless lol

 

Isn't memory BW, not compute, the most precious resource for Ethereum mining?

 

Ethereum looks very special with the requirements. Phoronix has a test with different AMD and nVidia GPUs: http://www.phoronix.com/scan.php?page=article&item=ethminer-linux-gpus&num=2

Doesnt look like that compute is the primary attribute to the performance.

 

Pls delete.

 

its mix of both compute and memory mostly memory though.

 

I dont think it mixes anything. The GTX1080 has twice the compute performance and 50% higher bandwidth and yet provides only a slight performance lead over the GTX1060...

 

nah it does, , cause when I undervolt and underclock my rx 580 rig but keep the memory frequency at 2200, my hash rates go from 30 per card down to 25. But if I go above 1370 on my core clocks I don't get over 30mh/s

 

Latency too it seems, cache&stuff...

My question was about power consumption in the end, as I see my fury X more demanding in some games, that in compute only stuff like mining or folding.

 

Probably perfect for ETH mining. If not for the price. But this as a cheap mining version, for example with INT8/FP64/ECC locked away by BIOS, this would fly off the shelves.

Interesting video ... bitcoin mining farm electric bill is 1 million euro/month.

 

I should not have searched for the price of the Tesla P4... Anyway, I have an old R290 taking the dust, I'll will use it for eth, and change my power supply by the same occasion.

 

Good time to be in the energy business lol.

 

RX 570/580 can be severely undervolted (some down to 780mv) providing amazing ETH hash/watt. My Rx570's do 27Mh/s with 831mv with 91watts (at the wall!). They barely get hot.

If my RX570 had better quality Elpida chips, that ratio would jump to 30Mh/s which is insane. The cards costed me 180€.


If you are wondering how many cards are being put into mining, check the difficulty chart for ETH https://www.coinwarz.com/difficulty-charts/ethereum-difficulty-chart.

This is a hole new business on its own. Gamers be damned

 

With the new Vega and (hopefully) better memory / cache / blablabla, I'm curious to see the mining perf for eth, zcash,...

 

That chart only tells me ETH miners are the ones who will be damned very quickly, not gamers.

 

I haven't seen this posted here yet.

Looks like shit is getting real.

 

200 MH/s ETH for 1000 watts? That's not very impressive, can do and actually did that with "wasteful" commodity hardware plus a little tuning. Base-system was a - in terms of power usage - thoroughly unoptimized i7-6800K with a closed-loop fluid cooling... so at least 100 watts, probably more wasted there alone.

But interesting to see that some vendors seem to have alternate plans in times of Polaris shortages.

 

Damned, I tried to add my old r290 to my gaming (mining when I have nothing to play) rig (watercooled 5820k@4.2ghz+FuryX in the same loop), and it's a no go... My r290 is a HiS IceQx2, a big ass card, and I couldn't put it in without changing some tubing... And I won't do that If Vega is good, It will replace my Fury X. The plan is to wait for a waterblock for Vega, and put it in the loop... Vega for gaming and mining, Fury X mining only... BTW, since my Fury X is very well cooled, it eat only 180-185w when I'm mining, so it's not that bad. I see some rig where it's eating 230+watts... (I measured this with... I don't know the english word, wattmeter I guess). My rig is pulling 105-110w from the wall when idle, and 285-290 when gpu mining. BTW it shows that the fury X sensors are pretty accurate, since it's showing 180-185w in hwinfo... Anyway, I digress, sorry.

I upgraded my PSU , so opening my case was not a waste
