Thanks for sharing. :) Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: goxed on July 30, 2012, 11:16:57 AM Quite interesting. Thanks

Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: Slushpuppy on August 03, 2012, 11:04:06 PM Now I know how much electricity a terahash costs
Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: arklan on August 04, 2012, 01:59:52 AM oh, very useful. shows me just where my poor little 350 mhash will survive until... thanks.
Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: muqali on August 04, 2012, 08:48:45 AM The $600 is what card? My 7970 is hitting 620M easily and it was just over $400.

Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: arklan on August 04, 2012, 09:35:16 PM oh, very useful. shows me just where my poor little 350 mhash will survive until... thanks. how long is that? well obviously it depends on how fast difficulty rises.. .but accordign to that, i've got a while yet. we're just over 2 million difficulty, and this shows 9.6 mil as the point 350 mhash is unprofitable. ...course that varies with electric cost, exchange rate, power use of my rig, etc... if it weren't for the impending ASIC's, it could be a year or more before i was unprofitable. course i fully plan to upgrade before it's an issue...

People who want to mine but have high electric cost should be able to invest with GPUMax or something i think it is, where they pay for someone else to mine, somewhere that has cheaper electricity cost Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: arklan on August 05, 2012, 07:40:51 AM last time i checked with the kill-a-watt, it was something like .36 kwh if i recall. i just moved in with my brother for a bit, so i don't know the electric rate off hand...

Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: arklan on August 05, 2012, 07:58:55 AM yea. mind you this is my main PC - the other card is an nvidia i use for gaming and whatnot. when i built this guy three years ago or so i hadn't heard of bitcoin, so mobo slots weren't a primary concern. i'm pretty much a sideline watcher as a result. until i can get some fpga/asic. kinda waiting to see how that shakes out while i save the money i'd need. (the job i start tomorrow ought to give a kick in the pants to the savings!)

(the job i start tomorrow ought to give a kick in the pants to the savings!) good definately more efficient if the COMP is already on for other uses Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: lickitysplit on August 05, 2012, 09:00:33 PM That BFL Mini looks pretty nice, especially because uses very little power and is cheap. Way cheaper than building a computer.

Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: 420 on August 09, 2012, 08:23:52 AM an easier to use link just to calculate cost or profit etc.

I am sure difficulty will be higher but it might give us more info on what to expect. Love the sheet by the way, Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: 420 on August 27, 2012, 08:19:30 PM Here, i made this table for know when a rig is unprofitable. https://docs.google.com/spreadsheet/ccc?key=0AoeSaFetN6hTdG5zY0tkeHdVWnY3cnNrZlM1SXhiYUE#gid=0 With the BTC per block going from 50 to 25 in December (maybe November) would you be willing or want to do another sheet reflecting that effect with the known data you have listed? I am sure difficulty will be higher but it might give us more info on what to expect. Love the sheet by the way, +10,000 (its over 9 THOUSAND!!!) Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: Evolvex on August 28, 2012, 11:09:19 PM Thanks for the sheet dude, not sure how to add new rows tho - complains about the range being locked, might be better to have the whole row editable. Very useful none the less :)
Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: VeeMiner on August 30, 2012, 02:14:49 PM I don't understand why is the BFL Single SC Mhash/sec =40000/86. Why is it divided by 86...
edit: I was looking at a different spreadsheet, it seems to be working in the unlocked one. Thanks for the interesting information... Title: Re: Profit/Loss dificulty limit calculation GPU/FPGA/ASIC Post by: dlasher on September 07, 2012, 05:14:06 AM Sheet presently broken or is it just me? Functions for diff/price/etc aren't working |
