Just seeking general info and/or experience. Seems like a good use for these older machines.
Hi stuipid question but what is Bit coins and how do I mine them
Internet currency and lately they have gone through the roof.
Thank you, I learned a little bit more from a quick google search. It seems very interesting to say the least
What do you mean by mining???? Bit Coins ? The only time I ever even heard the name is when a google search of mine showed up the silk road and I read on a write up about it that you used bit coins as currency on that site.
Look into performance vs power consumption.
Last i looked the best way for a home user was actually offloading the processing to ati video cards, the 5xxx series (iirc) were a number of multiples better than a modern i7 range cpu. Also it was on the verge of dedicated bitcoin machines hitting market which would have a processing power many times higher than the ati setups. The dedicated asic machines are now out.
Basically. At this point with dedicated machines hitting the market the "difficulty" which is what payouts are based off of is increasing at an incredibly rapid rate based off the total processing power of all the machines on the network combined. The power consumption of a g4 machine vs its processing ability would never work out, even at the high current value of coins.
according to this the 1 g4 on the list has a hash rate of 1 mhash/s
an ati 5970 works at 700 mhash/s
an avalon asic is over 60,000 mhash/s
look at the spike in the first graph.
Laws of economics basically state that producers of a given good will appear to satiate demand at a given price point.
With the huge amount of press and spike in bitcoin value over the last couple months. The vast majority of "production" is going to be done by a small number of parties with deep pockets for equipment. Its hit the point where mining is far beyond basements/closets and old machines.
Thank you Good Sir! Perfect answer. You just saved me $250.
I'm afraid you've pretty much missed the boat as far as mining goes. GPU mining (as shown above) is several orders of magnitude more efficient than CPU mining. Unfortunately you won't get anywhere near a decent hash rate out of one of these things - just too old.
Thanks. I've come to that conclusion as well. I told my buddy about it yesterday and he informed me his mom has had two G4's and one G5 in closet at home for years. She's an elementary school principal. I could have gotten them for free. So I really missed a grand opportunity. Feels bad except I'm still going to get the G5! Woot!
DON'T buy an ASIC!!!
