Bitcoin Mining GPU Performance Comparison @ [H]

Electricity is included in my rent, plus I live in a cheap market

Be careful that you double check what your electricity rates are. Here in Los Angeles, depending on what tier you fall into, you can easily pay .13 cents/kWh which would cut the projected profit in half. $60 minus $27 in power costs for a 5770 using 300 watts from the wall and producing 200mHash/s.
 
Right now the 5770 and 6770 provide the fastest turn around for your money... just a FYI. Tweeked they do 220 Mhash a sec and only cost 94 bucks AR on newegg. the $129 5830 is right behind them, but eats more electricity.

Yes the value fluctuated like a stock, so there is risk that you won't be making the current $14 per coin in the future. There's also a chance you could make more, but supply is increasing faster than demand so I don't see that happening.

Also, the rate at which you earn coins goes down over time, so you will have to work harder to earn the same amount of coins over time.
 
Is this the new furmark?

No. Furmark doesn't pay you anything to run it.

I would recommend doing this on a system that won't be used at all. I killed two cards, on one card I was just browsing the internet when it failed. My brother also killed his 5750, but that was running constantly at over 100 degrees Celsius.

If your killing cards its because your running them way over the temp threshold or using a cheap power supply. Invest in better cooling and a better power source or don't mine.

I find it hilarious that I sold each of my 5870's for more than a 6970's retail value and yet the 6970's perform better. Sense? Bitmining makes none.

5870's will outperform 6970's but you need to be running them off the Phoenix -phatk kernel with different flags than the ones used in the Performance Comparison here. The 6XXX series GPU's will do fine however using the default OpenCL Poclbm kernel with "-v -w128 -f1" flags.

I would still go with the 5830 as being the best performer for the price. It will do over 300Mh/s easily.

Only problem with the 5830 is power consumption. It's almost that of a 5850 which can also out due it. Though 5850's are hard to find unless used. Newegg/Chiefvalue has had some 5830's in stock.

I still agree with SulSeeker and say that the 5770/6770 is the best valued card atm.
 
When pricing cards don't forget to factor in PCIE slots. Once you're full, you're full. Good price/value or not it's a new rig if you want more.

And yeah as someone said... looks like a coming difficulty increase...
 
Can someone tell me what the fuck is a MHASH?
And what are/is the GPU actually calculating, and for what purpose?
Aren't you concerned you may be running programs to hack into something?


foil hat placed..........;)

Looks like now isn't the time to really get into the game as far as difficulty increase and the amount of people that will begin mining now.

And over half of it is held in 1 mining pool.

SA literally halved the value of Bitcoins in one day by just posting various "SELL SELL SELL!!!" topics in various forums.

Think about this the next time you decide to invest in what is basically internet monopoly money.

Unless you have extremely high power costs where you live the 5830 will still have a higher Mash/$ than the 5770 because overclocked the additional hash rate of over 300Mh/s is going to make up for the additional power draw.

I'm also pretty sure the newer non-reference 5830's shipping from Sapphire have a lower power draw than the longer reference card 5830's and you can see in the newly updated comparison chart here of the top 20 mining cards the 5770 has a Mhash/J of of 1.45 while the 5830 is 1.4 at stock speeds so not a real big difference.

I'm gonna try this out for a month on a single 6970 and see if it's worth the increase in the electricity bill :p and if so go run it on both 6970s.

Thx for the comparison.
You will only get around $3 per card, that might be worth it, but it was nothing compared to $12 a day around a month ago. I have stopped since it just doesn't seem worth the noise, heat or worry of breaking a card, especially for only $2-3 a day.

My cards were not over the threshold. When my last one died it was running at 68 degrees Celsius. The max I ever saw it reach was 76. And my power supply is a seasonic 850w, I doubt that's the issue. It could also be that MSI cards are just made of cheap components, but I don't know. I'm just saying it may not be a good idea to mine on the pc you use everyday or just do it while you're sleeping or at work. You can't even play a video on your computer without the whole computer freezing with a 6900 card.
 
Kyle, Saturday can we see an Intel/Bulldozer comparison?
 
On the flip side, if you need a gaming card, Nvidia's the way to go... they're all in stock at the moment.
Pst, your fanboy is showing.

And here comes the armchair economist cavalry :D
 
You guys complaining about electrics rates have no idea how bad it is in Northern California. Rates are simply ridiculous. For the highest tier which you will probably hit running 1 computer with a few cards in it 24/7 is 30 cents a kWh and 50 cents per kWh during "peak hours" which are 12-6pm. These are the reduced rates that went into effect last month from 37 cents and 57 cents...
 
And here comes the armchair economist cavalry :D

Indeed. I was getting up my hopes because none of them had chimed in so far.

Bitcoins are an early market , there is risk involved. If you don't understand that or are willing to except it do not get into Bitcoin mining ..bottom line. This is not for the faint of heart.

No one knows the future of how the market will ultimately work out or as the difficulty increases if it even will be worth devoting the power and effort into generating coins.

A good way to protect yourselves is to invest in the best price/performance ratio GPUs , generate as many coins as you can in the next few months and keep your eye on the market value. Also look at the difficulty , if there are any dramatic increases then you should evaluate your setup and the cost to run it versus the profit you would generate and decide if its worth while to you. Bitcoin mining is a "long" game kind of investment , generate coins ..sell when they are valued high ..

Whatever you do don't go out and buy 2 6990's as a new user , invest in a smart and cheap setup. If things go bust then at least you wouldn't have dumped thousands into your setup.

Agreed. My new HW (5830 + PSU) is now paid for by mining, but if I started now, it wouldn't be for a long time. Making more profit trading bitcoins than mining right now....
 
BTC Mining Calculator this will give you a general idea at the current difficulty

keep in mind that at this point of this game that making any profit is marginal at best . do you have a cool place for the hardware you intend to purchase ? if not then you will be spending more on that to cool you machine down.

not all 5830s are going to get you to 1100 gpu speed , i have several that wont go about 920 gpu speed without voltage increase. still these i think are best value for this but resell later probably wont be

Jen
 
Why no love for 4x overclocked 5850s?! 400mhash x 4, just increase voltage to 1.2 and gpu to 1000mhz while setting ram to 300mhz. And where is the [H] mining pool??? Arstechnica and Reddit have their own pools!!

You can't even play a video on your computer without the whole computer freezing with a 6900 card.

Right-click on any flash-based video and go to settings > uncheck "Enable Hardware Acceleration". Now the computer won't lock up when playing a video.

It only seems to be a flash issue though, since I can load up a game like Plants vs Zombies while mining with no issues whatsoever (although it can get a tad choppy sometimes).

I'm guessing your cards were just faulty or it was some other issue.
 
wait wait, we can make money with our massive beasts of machines(provided they AMD)? man and here i was thinking i just spent money on em >< lol. Guess i'll have a reason to keep my machines running now when i'm afk :D
 
Now, I've read about this bitcoin before and still don't quite understand it fully. Maybe someone can give me a quick summary about it.

1.) How do you earn money? Or, more specifically, where does the money come from?
I know you can't create money from nothing yet I see it's possible to convert bitcoin to real currency.
2.) I see that bitcoin is similar to folding, is that entirely true?

3.) Importantly, is this even legal? Taxable even?

4.) Can you purchase with bitcoin alone?

5.) How does this even affect video card pricing? I've seen a few posts here on [H] mention that bitcoin crashed/hurt the video card market or something along those lines.

Thank you.
 
makes me wish amd would just bite the bullet and use the cuda/opencl apis to dev their own compatible gaming physics platforms, even porting physx directly would give them so much leverage over nv the way things are going right now. most gamers can't really see the advantage in buying amd when they get left out of key features, what good is a blazing fast card when you don't get the eyecandy? nvidia is hanging on a thread here, such wasted opportunity for competition.

AMD already allows DEVs hardware access to the GPUs to include such things as Physics engines accelerated via GPU, if the DEV wishes to create one for their game. It is up the game devs to include these features in their games. Of course, like anything, you use the GPU for other things while gaming it can affect your graphics performance.
 
Kyle, can you please explain how you were able to get GPU-Z to run while using GUI Miner? Every time I try it locks up my system.

You mine coins, then transfer the coins to a site like mtgox and from there sell for USD
2.) I see that bitcoin is similar to folding, is that entirely true?
I suppose it is similar in some ways.
3.) Importantly, is this even legal? Taxable even?
It's legal.
4.) Can you purchase with bitcoin alone?
Yes, lot's of stores selling bitcoin related items/hardware accept bitcoins in payment
5.) How does this even affect video card pricing? I've seen a few posts here on [H] mention that bitcoin crashed/hurt the video card market or something along those lines.
5000 series went up but has seem to settled now, 6000 series has also gone up from what i've seen.
Thank you.

Answers based on what I think are in blue.
 
I love that my 4850 performs better than the 560 Ti haha.

Heat was a big issue, in our testing system it is open-air sitting on a desk. I can only imagine how much hotter it would be in a case. You really really want good cooling in the case, but more importantly IMO is a custom video card with a beefed up heatsink/fan on it, it will benefit you the most and keep your cards happy.

Not really. It's hotter than "typical gaming" yes, but not as much as Furmark. Bitcoin mining is somewhere in between.

I think Bitcoin mining is comparable to Furmark, it stresses the GPU at 100%, and scales perfectly linearly across all GPUs in an array. Its a good test of maximum GPU power, and heatsink/fan abilities to keep the card cool. However, it doesn't stress the memory portion of the card.

wait wait, we can make money with our massive beasts of machines(provided they AMD)? man and here i was thinking i just spent money on em >< lol. Guess i'll have a reason to keep my machines running now when i'm afk :D

You better setup a dedicated box if you really want to get anywhere, but watch that electricity cost.

Kyle, can you please explain how you were able to get GPU-Z to run while using GUI Miner? Every time I try it locks up my system.

I didn't have any problems getting GPUz to work, didn't have to do anything special. I had some crashing in one scenario, but it ended up that I needed to have the CrossFireX bridge connectors installed with CrossFireX enabled for the lockup to stop. I tried to do it without CrossFireX turned off to see if I could still mine on each GPU, but the system just locked up when I enabled the last GPU. It wasn't related to GPUz.

The procedure I used was to first launch GPUz, move it to the side, then launch GUIMiner and then launch Bitcoin as a solo server, had no issues with GPUz doing this. BTW, I'm using the latest version of GPUz.
 
Answers based on what I think are in blue.

Pretty sure his answer to 4 is BS though. I don't see "lots" of stores accepting bitcoins, and I don't know what "bitcoin related items" even means. They might be destined for black market internet currency, but don't expect to be using them on Amazon ever.
 
Now i know why there was a huge spike in overall performance on bitcoin network :) Ah well gone from over 10 coins a day to 2 :( Been fun while it lasted hopefully people get bored and allow the difficulty to drop again. Anyone looking to invest huge sums in mining would be better advised to play the market and buy coins. If you have a few cards lying around then by all means utilize them.
 
Actually, in many cases, downclocking the memory results in higher hashing speeds. The prevailing theory is that it's due to the latency being lower on the slower clocked memory.

It's probably both, higher allowable GPU overclocks, and reducing memory latency. At any rate, sure, if all you need are more Mhash/s and clock speed, drop the mem clock, get GPU clock as high as possible.
 
here is a simple explanation of how it makes money. Bitcoins use hashes to verify transactions are legit, and when you mine bitcoins you are calculating the value of those hashes for the transactions of selling and buying bitcoins. You are creating money out of thin air the same way the fed (in the US) prints money. The people who made money off bitcoins where the ones who did a lot of mining when it was easy and sold when it got to $26 - $30 a coin after the major news story on it a couple months ago. A lot of people pulled out after MTgox had people's money disappearing as it hacked or he did it himself and came up with the story to cover for it, anyway some one sold off 4000 bitcoins which drove the price down to pennies but was brought back up by the people buying it while the price was low figuring the price would go back up.

If your going to get into bitcoins I would definitely mine over buying them but you are supposed to be paying taxes on them if for capital gains if nothing else INAA. I would talk to a CPA (certified accountant) over what type of taxes you owe on them. Everyone has a log of who you bought sold from and how many but not what you bought with them.
