Interesting comparison.
however, where you see these prices for R9 280X?
I see ~$240 on Amazon for new and ~$175 for used.
Refurbs are ~$150

I am thinking, maybe to do some Ethereum mining for fun, but I could also simply buy more ETH.
I did buy some in early January and some after trading begun and quite pleased so far to say the least.

eBay. Took the average for the 7950/7970/280X which are the best bang for the buck for Ethereum. The brand new cards, aren't that much quicker.

They really arent, i'm not sure what's up. The only difference is more RAM, so it could mine Eth longer. But we dont know what will happen to Eth in the future and it might switch to POS before we can cap out the 280x anyways.

I probably don't know what to look for, but i don't see the prices that you mention (i see initial bids with these numbers, but nothing like this in buy it now).

Well, i just find out that my PC with the highest PSU power (300W; HP 500-267c desktop) can only support GTX 750 Ti, but not R9 280X.

If you guys know, would it be easy to hook up Corsair 500 or even spare EVGA 1300 to the card?
I never did anything with GPU cards before, so please forgive my newbiness in this department.
maybe something new to play with as bitcoin mining is getting depressing lately.

Depend what the card is but i run a 5 280x rig on one 1300. Multi PSU is not a problem with the mobo connector y splitter or you could also power everything at the same time using the surge protector switch.

For the price, he prolly refer to this;
http://www.ebay.ca/sch/i.html?_from=R40&_sacat=0&_nkw=r9%20280x&LH_Complete=1&LH_Sold=1&rt=nc&_trksid=p2045573.m1684

As you can see it comes down to about 160$~ Shipped.

I understand what you want to say, but your comparison is not entirely right.
First, you compare used card with new miner. Prices for such used cards are mostly higher.
And Antminers are usually rock stabil - this is not possible to say for GPU mining (I had in the past various 200 GPUs).
I had a lot of defective cards, very often I had switch on/off my GPU rigs.
Also GPU rigs are not so compact as Asic miners.

[Cashew]

Don't worry about this. This is not only Bitcoin which is bad performing but also Ethereum which is rocking. Bitcoin will be back at the halving !

Wat. S7 used or new is same price, we can take a Used S7 priced at 800$ too if you want. And i dont know what you're doing to your GPUs but i got 0 failure in years. We can also take the price of a brand new 280x if you want, which is only 40$ more. The math is roughly the same.

[VirosaGITS]

Eh maybe I should turn my amd rig back on, that or see if the maxwell cards I have been stocking mine it as well.

Well you missed about 3-4 months of good profit with them tho. The thing with Maxwell is they work fine but while they take half the power consumption they also hash at about half speed. So you're left with a low $/GH ratio.

But if you already have them on hand... yeah check it out.

[adaseb]

The prices might not be exactly accurate but the point I am trying to make is that a GPU is cheaper, quieter, less power, makes the same amount of $ as an S7, and will retain higher value most likely with the halving due.

Most people these days can't even mine with 10 cents power but with a GPU its still possible. And if you buy a brand new GPU for $300, in one year it will still be worth at least $150, If you pay $3000 for an ASIC in one year, it will be worth like $200.

Is only this thing needed to mine cryptocurrency, or also other things get involved?

I heard that if u use gpu's to mine coins, that after a few years they will be dead because it ran too long on max power.
So it basically dies, is that treu or just a story?

From what I read, the problem is not the moderate heat (like 80°C) but the temperature changes dilating and reducing the chip which physically breaks the chip.
Supercalculators run at 100% for months/years and they don't break.

Because you cant mine ETH with an Antminer only with GPUs.

ETHEREUM has the #2 market cap to BTC right now, its more valuable then LTC. But altcoins aren't always as stable as BTC.

Algorithms and asics, so think of it like this a Bitcoin pays for doing Math type A (we will pretend it is division) and Ethereum does Math type B (we will pretend multiplication).
A GPU can do all types of algorithms, So lets say it can solve 15 million division problems a second or 3 million multiplication problems a second. That's fine and dandy, but then comes out machines that ONLY do division and that is it.

They run the same wattage as a gpu but do 300 billion division problems a second and the difficulty of having the winning answer in time with gpu is lowered. Now it is so much lowered it is nearly IMPOSSIBLE but the amount of electricity to run that graphics card is not changing.

Now Ethereum is running the different algorithm (so again pretend multiplication) while there are no machines made to do ONLY (yet) multiplication the graphic card is the only way to do it and mine ethereum. The division machines can not do multiplication and never will.

Understand?

Nutshell version:
GPU does everything, but its extremely slow compared to circuit and processors solely designed to hash a specific instruction over and over. There are no ASIC for Ethereum's algo, therefore GPU is very profitable for it.

i wish that was the case with btc, as we are wasting a lot of computations on a very few transactions.
basically, ~5th/sXday/transaction or one S7 running the whole day to do ONE transaction.

Aprox 20% of my 200GPUs within one year  had some problems/defects. With Asic miners this number is much much less.

It is not insane amount, it is common, when running 24h 1 year with a little overclocking in the room with high temp

mostly it was: MSI R9 270X, MSI R9 280X, Sapphire R9 290X (but also some trouble with Gigabyte R9 280X, Asus R9 280X)

But fortunately, most of them were in warranty.

I've had all of mine running 24h for 2 years now and i never had a failure, just annoying fans. 40 failures out of 200 is insane. I'm not sure what temps you were running them at though.

[adaseb]

Maybe if you were mining SHA256/Scrypt then the failures rates were high because you were stressing the GPU to the max. Most new algos now like X11 or ETH don't stress the card as much.

Plus a GPU is much more reliable then an S7 which apparently has more failures rates.

You are not pushing hard then.   I go back to GPU day's and I would push mine hard as GPU companies had amazing RMA policy's  back then.  I was about making as much as possible, and granted a few times I pushed to far... puff of smoke.  But overall I gained more doing this as I was pushing all my rigs.

The thing today about GPU's is you just don't make enough off of them to ROI.  You are going to have to sell to get money back. You might make a small profit but you will not make ROI these day's GPU mining.

Huhh, so i would push them hard actually and they would crash. No damage done, lower clock by 5mhz step until it stop crashing. I keep them at 65-75C, i never had a problem. Sound to me like the GPU's VRM must of overheated. Happens if the heatsink doesnt cool them down.

How is that different from mining with ASICS? Most people rely on resell value to get some sort of ROI.

That's why many people hate Bitmain for halving the price of the S7 and killing the resell value.

GPU/Asics are like apples and oranges.   You could bot on GPU's and count on getting 3/4 to full on some selling on seconday market to gamers or other GPU miners (this was a while ago I have not GPU mined in years).   But it was always very high on sell back.  And ROI time was around 90 day's which was pretty amazing.

Now asics.... they do not ROI anymore near 90 day's.  But beside that they never really did hold value like GPU as there is not that other market for them.  Go all the way back to asicminer block erupters... you sold less then you bought for.   So asics never sold for full on resell value you go into it knowing that.

It was not overheat trust me.  I remember one GPU as soon as I set it up on intensity to high... instant smoke out of cap on it.   I kept them all cool so was not a issue there, but I pushed them hard.

It was directly related to intensity of GPU settings.   They might have made it harder to do now I have not kept up with mining with GPU software, I'm would guess it has changed some in past few years.  I had all the proper risers to get more space and spread them out, there was great cooling.  So no issues on heat did not cheap out when making the rigs back then.

[Amph]

the comparison is a bit off because ETH is skyrocket at the moment, you should have compared the two whne bitcoin skyrocketed to 500 and the diff was 100B

Thank you I have not kept up on mining algos on GPU's but it makes sense they don't stress it like they did back when I GPU mined.   It was so common for a card to go out when I had a decent amount of rigs I had a form letters for 2 different GPU card companies.   I had a lot of gigabyte as I really liked them.  And other one I also had was SAPPHIRE GPU's.  Seems crazy to some today but they would run out of GPU cards so many were purchasing so you could not always get the brand you wanted.

I know I pushed them.  But back then they had such good RMA coverage it would have been crazy not to push.  I conspired it a cost of business sending in for RMA when dealing with a decent amount of GPUs.

You are not pushing hard then.   I go back to GPU day's and I would push mine hard as GPU companies had amazing RMA policy's  back then.  I was about making as much as possible, and granted a few times I pushed to far... puff of smoke.  But overall I gained more doing this as I was pushing all my rigs.

The thing today about GPU's is you just don't make enough off of them to ROI.  You are going to have to sell to get money back. You might make a small profit but you will not make ROI these day's GPU mining.

Huhh, so i would push them hard actually and they would crash. No damage done, lower clock by 5mhz step until it stop crashing. I keep them at 65-75C, i never had a problem. Sound to me like the GPU's VRM must of overheated. Happens if the heatsink doesnt cool them down.

It was not overheat trust me.  I remember one GPU as soon as I set it up on intensity to high... instant smoke out of cap on it.   I kept them all cool so was not a issue there, but I pushed them hard.

It was directly related to intensity of GPU settings.   They might have made it harder to do now I have not kept up with mining with GPU software, I'm would guess it has changed some in past few years.  I had all the proper risers to get more space and spread them out, there was great cooling.  So no issues on heat did not cheap out when making the rigs back then.

Well i remember in the Scrypt era, i heard a few people break their GPU's, but when i did tests myself, my 280x would do 745Kh/s and if i took diff from 13 to 18, they would work insanely high, get 765Kh/s but pool side there would be not that much of a difference.

Imo i dont think a 2% speed difference thats not even fully effective is worth doing high intensity vs low. Certainly not worth the downtime of having to RMA Gpus.
But thats just me i guess.

the comparison is a bit off because ETH is skyrocket at the moment, you should have compared the two whne bitcoin skyrocketed to 500 and the diff was 100B

or compare the two when ETH was at 360k satoshi

Its plenty comparable, i been mining ETH for a while now and even when it was crashing low, it was pretty close to S5's profit on a per watt profit.

[Biodom]

Since this is now in speculation, I would like to point out the following:

1. Eth is now 2nd coin by the market cap with $5.25/Eth. Still, just 7% of btc market cap; will probably go to at least 10%.
There are already ~77 mil Eth, its market cap is $400 mil and daily trading volume is ~1/4 of btc, so it went from an alt to a somewhat serious contender.

2. Eth is now being taking seriously by the ecosystem. 57% think that it will play a large role.

3. Investment sentiment toward BTC is really bad: ~90% between lukewarm and "bubonic plaque"
reference to #2 and #3 here:
https://medium.com/boost-vc/boost-vc-bitcoin-sentiment-in-pie-charts-8d81731664b7

4. too little coding and too much debating in btc, hence a sense of exhaustion.

5. growth in btc hashing power that is uncorrelated with transaction growth, discouraging individual participation.
I think that POW algorithm in btc needs some mods.

My conclusions:

a. should have bought more eth for btc hedging in the last 6 mo. It is up almost 800% from the lows.
b. btc is probably about to go up since investors usually have no clue and bad sentiment is typically bullish.
c. as far as eth mining-I might try it at very low scale with 750 Ti just for fun.

Interesting thread, thanks to OP for starting it off.

I have been mining ETH with GPU for a little while now a week and a half basically and did pool mining at first for a little while but thought I would give Solomining a try.

Has not been too bad, only have one R9 280X with around 24MH/s hashrate and I found two blocks in 3 days which I thought was quite good going.

Will leave it running for a couple more days before going away as don't want it on when I can not keep an eye on it.

Mining ETH on a GPU does not stress it as much as what Scrypt did, that's for sure, from what i can see.

With Scrypt running at full hashrate, it was hard to do anything else on your PC but with ETH even when mining, you can still do other tasks without it affecting things.

You say it was due to temperature, you did not even know it could happen due to intensity.  Then you turn into a expert again.   When you say your 280x are you saying you mined during it with 1 GPU?   You have to understand 1 GPU compared to many rigs is like apples and oranges.  

Also different brand 280x and models got different speeds, had different best settings.  There was not a 280x setting that was for all. You act like a 280x is one single item. Different ones preformed different there all brands/models did not get same speed. Look back and you will see this.  Look at RMA's back then it was common if you had a sizable amount to have do them.   It's not that you wanted to it was a cost of doing business.

The best question is why let this go further?  There is no point to argue GPU mining from years ago.

I had 4 rigs, Tri-X and Gigabyte Rev 2. I picked these two from said considerations.

have you tired the r9 390s and how much hash can you get out of them?!?

R9's 390s cost a lot.   They do 27-30 a card

I did get four from Amazon warehouse at 291 each which is a good priced.  Used 30 day return policy

i'm with nvidia on this thing, i'm still getting 22 mega per card, but etheruem is not the best profitabe coin at the moment, there are new shitcoi that are more profitable, loco, thecred, and the recent feathercoin

also 390 consumption is too high, i'm sitting around 160w per gpu with my small rig made of 970

[QuintLeo]

Hmm, looks like my machine with the triple GTX950s aren't so bad after all on Ethereum.

 Only about 10MH/s per card but each card is eating LESS than 100 watts - looked at them with GPU-Z today and they're around 75% of TDP (TDP is only about 110 watts for these cards as I recall) - and even though the entire machine is FAR from optimal for mining (the A10-7860K is TDP 65 watts by itself but I suspect the way I'm pushing the GPU for RC5 work it's pulling more like 80-90 PLUS the motherboard and HDs) it's still only eating about 350 TOTAL watts when mining.


 8-)



 I can use that machine for other things, but forget trying to game on it while mining, TOO much other stuff going on. It DOES work for web browsing, though, with some noticeable but not horrible delays loading pages/updating.

After 2 months of posting this, the 280X still seems like a much better alternative to the S7, even though the S7 is about $500 now instead of $800.

The 280X makes only 70% from what it made back in Feb 10th, so I guess after the huge pump and huge difficulty increase, its still pretty impressive.

It was good already having some 280x and buying some 7950/280x or such at 140~, but now i been buying strictly retail low TDP cards, with better W/MH than Nvidia and r9 2XX AND much much better MH/$ than Nvidia, though not as good as used GPUs (i guess, but who knows people are still buying like crazy even when retail would be betteR).

I'm disappointed that Nvidia have no place in Ethereum, the prices of 970 just doesnt meet the performance. But once you move away from Eth, maybe you can go to a coin that is OpenCUDA friendly?

The thing that scares me is people chase profit who make asic chips.  There were X11's being ran that we did not know about when the asics were made, due to keeping them private.   Now you can buy an asic that does X11 due to them being used and they already made money back selling is just a bonus.

I think if ETH remains profitable you can count on someone trying to make asic chips for it.  How long it takes.. and if it remains private we will not know.  But I hate that possibility of dropping money on GPU and an asic can come out and blow it away.

It should be Okay, ETH is planned to go to PoS SoonTM. If you care for the value of Eth anyways. For continuing mining, though, tough luck. But thats where GPUs shine.

I guess in several months we might know better. Not before Q4 is my guess. So long enough that you dont need to worry about it at current profitability. But soon enough that ASICs probably won't hit. Also the cost of making ASIC using a DAG would probably be expensive, and doing it without a DAG would probably mean very very low performance.

So i'm not worried. Worse case scenario, Switch GPU to something else. ETH is no longer the "drop everything and mine that" currency. It's still good but private miners do better, now.

So I take it from your comments that you aren't trying to hold/save the bulk of the Etherum that you mine? If that's true, what do you exchange it for?

Split between savings and more hardware. Holding is money wasted imo. Unless you get lucky and the price explode, anyways.
