Topic: ASIC's hitting later than expected = Good thing? (Read 6146 times)
When i had my 7970 system mining it was producing 650Mh/s and only pulling 380watts at the wall. That included a gaming system setup (quad-core amd cpu, 6gb ram, optical drive, traditional HD, and a couple of heavy duty 120mm case fans). That number also counted my wireless router, cable modem, plugged in monitor but turned off and power strip. There is no way that card is pulling more than 250watts, and i'm sure it's closer to 220-230 at full load with simple low risk setting like 65% fan 1100gpu/950ram at 67degrees. I'm glad i made the right choice. That card will serve me for years to come if i keep it.
My quad 7970 water cooled system uses 1KWhr at 2.6ghs, stock voltage, 1160 core, 170 mem.
That is 2.6 Mhash/Joule. Better than the 5770, as expected.
Yeah, just that one of the cards is lazy and has kept me lowering the core clock. I used to mine at 1175 mem with stock voltage, but it seems that it kept crashing and had to lower 5 mhz every 2 months or so. It is my second card, and blinks a red light on the PCB, what does this mean?

My system:
1000 watt Kingwin PSU
AMD 965BE,3.4ghz,no OC
8 gig DDR3 1600 (PC3 12800)
3-320gig HDD's
5-80mm fans(lighted)
Visiontek 7970
While mining the whole system uses 380 watts,while idle 150 watts.I'm assuming my 7970 uses 230 watts max (1050mhz gpu clock,1265mhz memory clock=620mhs).
Still beats my 6970 xfire setup,680 watts for 820mhs.Glad I upgraded

7970 - ~300w @ (lets say) 600 mh/s.
Huh? I have a single 7970 "space heater" running at 620MHs and drawing 275W at the wall for the entire system. Admittedly the other components are efficient (Sandy Bridge i5, SSD, 80 Plus platinum PS), but still ...Welcome to the world of people tweaking numbers in order to save face in an online argument...
We used maximum draw per ATI for both cards. Stock no tweaking the 7970 pulls down ~560.
You are still wrong. Because the official TDP of the 7970 is 250W. So even when looking at stock numbers, the 7970 is more efficient by ~21%:
- 7970: 560 Mhash/s at 250W = 2.24 Mhash/Joule
- 5770: 200 Mhash/s at 108W = 1.85 Mhash/Joule
If you move the argument to undervolted/fine-tuned settings, or to actual measured power, then the 7970 increases or keeps its lead because, as I pointed out, it doesn't even use close to 250W when mining (only ~200W).
7970 - ~300w @ (lets say) 600 mh/s.

7970 is 32nm. 5770 is 40nm. The 32nm chip is naturally more power efficient.
Also you made the exact mistake I predicted: incorrectly assuming the 5770 draws 0W at idle therefore you think mining only takes 42W. The 5770 actually draws 18W at idle per its specs. That means your card as a whole is closer to ~60W when mining.
Taking into account this 18W baseline load is important when comparing different cards. Or else, imagine if a card was so inefficient that it would draw 100W when idle and 105W when under load. People would be claiming that mining only takes 5W, therefore making it the most efficient card of all!

Argue it anyway you like - you're still incorrect. Measuring at the wall with 3x 5770 and then measuring the same machine with a 7970 instead... will clearly show which is ahead.
per specs maximum draw for a 5570 is 108W. Lets use that number. My cards (which are drawing ~75 are getting over 200mh/s).
5770 - 108w @ 200 mh/s.
7970 - ~300w @ (lets say) 600 mh/s.
These numbers show I was correct! - the 7970 is more power efficient (in fact a lot more because your numbers are out of whack... at 600 Mhash/s the 7970 draws ~200W -- I measured mine at 193W with a clamp meter). Not sure why you say I was "incorrect"
The difference between the idle draw on the 5770 and the 7970 is 3 watts.
Yes but when you ignore the 18W at idle for the 5770, you ignore 17% of its total power draw,
and when you ignore the 15W at idle for the 7970, you ignore 6% of its total power draw.
See the difference? 6% vs 17%? This is the significance I am talking about.
Yes, me and many people get 650-700 Mhash/s per 7970.

Now based on 'worst case' numbes the 7970 is slightly ahead.
The difference between the idle draw on the 5770 and the 7970 is 3 watts. Also idle doesn't matter, since you can't mine while idle. It's fine, rest assured that your 7970 will probably resell for a few hundred bucks once asics hit... while I'm losing slightly more money if I can't resell mine. Due to them only costing 1/6th of the price.
I for example run some fpgas, and a bunch of 5770 (most power friendly mining card there is if you configure it correctly).
Hum, no. A 7970 beats the 5770 any day in terms of Mhash/Joule. It does 3.1 out of the box. 4+ when undervolted/underclocked.If you think your 5770 beats that, you must be incorrectly measuring its power consumption (eg. you measure at the wall and only measure the difference between idle and load, and incorrectly assume the card draws 0W at idle).
It's possible I screwed the the math.
I'm showing a difference of 42 watts between idle and loaded - with a single 5770. The cards limited to 75w (per ATI). A 7970 is ~200 watts difference between idle and load. (and limited to 250 per ATI). Are you getting 600 mh/s out a 7970? If not then my 5770s are out preforming you and using less power.

Maybe miners are playing chicken. They know if the other guy quits it will make them more profitable so no one wants to pull the plug.
That's not it at all.
Some of us were actually smart and did research before we got involved in mining.

My incomes gone from ~2btc per day to ~1.2 btc in recent weeks. My power bill for my whole place offset by solar (which is junk in winter) but right now I'm heating via mining and paying about $90 per month on an electric bill, which is only slightly more than I'd pay for firewood or gas heating.
Price of btc is still rising, and should continue to rise until the release of ASIC. By my speculation, it's going to stabalize around 15-16 usd per before march (which is when I think asic's are landing).
Yup, I'll get more profit from my GPUs. As far as I'm concerned I'd be happy as a pig in slop if ASICs got delayed another 6 months, lol.
You're kidding right? Or do you have free power? With the reward halving - I am shutting down. Use the bitcoin profitability calculator and see if you are actually making money after Wednesday with 25 BTC:
http://bitcoinx.com/profit/
No, I'm not kidding.
I have a HTPC that's on all the time anyways so I don't count the "idle" motherboard power usage as that part of the power consumption would be on my monthly bill, bitcoin mining or not, houses 2 cards. I have an atom board with 1 core disabled, only uses 20W, have 2 cards on that one.
The calculator is roughly in line with my quick match calculations:
Coins per 24h at these conditions 0.1418 BTC
Power cost per 24h 0.73 USD
Revenue per day 1.92 USD
Less power costs 1.19 USD
System efficiency 2.79 MH/s/W
Mining Factor 100 at the end of the time frame 0.17 USD/24h@100MHash/s
Average Mining Factor 100 0.19 USD/24h@100MHash/s
Power cost per time frame 89.41 USD
Revenue per time frame 215.94 USD
Less power costs 126.52 USD
Also, where I live (Canada) it's winter now, and it's cold here, temps in winter typically range from -5C to 2C on average. So the heat generation is not wasted, so it's profitable to mine AND I get a lower heat bill too (which is more profit, though harder to measure).
I didn't know there would be a 2 month delay, I wish the ASICs would've been released before the block halving.
And another month to go at the least.
42 days minimum

Get out and buy BTC with your dollars. If you think ASIC's are coming at all soon, you'll soon be outgunned by not only all the buyers of ASIC's... but the ASIC companies themselves mining with their stock. Imagine if AMD put all their unsold GPU's to work mining BTC? Imagine if for every GH you buy from some ASIC manufacturer, they create 3 and use 2 to mine for themselves. This is what you'll soon be up against.
the only benefit is getting the btc now and paying the electricity cost later, but at a loss it is mostly worth just buying btc with usd instead
But you don't get your BTC now. You get them later, in diminishing amounts, and you have to pay for the electricity in constant amounts with diminishing returns.
If you buy BTC now, you just get them. Done deal. Nothing further needed.
