Topic: GPUs vs Block Erupter USBs? (Read 2934 times)
Getting a good GPU is always a nice investment just because of better quality graphics on your computer, mostly with games. Also, if you like mining altcoins, GPUs are still pretty much king around there.
You can buy Block Erupters for 1 btc from btcguild.com if you're so inclined.
Hi all
My first stupid post as I'm a Newbie how is just try to buy some USB or Block Eruptors items. Seems I can't do this without get out of my Newbie state? Or does someone sell some items?
I will pay with wire transfer, after I got the items

Oh, PS. You do know these are a very bad deal don't you (popular though nonetheless). Are you expecting to make a profit or just laundering bitcoin?

You also have to factor in that the Block Eruptors are an easy way to add hash to an already overloaded 15 AMP circuit. You can milk ALOT more hash out of a residence! Running them on a desktop already being used for normal purposes is alot easier. I tried to add a 7970 to a Dell and it was a fail due to lack of BUS power. I did not know about powered-risers at the time so maybe it would have worked that way...
The other missing factor is heat. Depending on location heat can be a big problem with a lot of GPUs.
Asics suffer from even more severe heat issues than gpu's. The first BFL labs units were errible for heat and even the block eruptors suffer from heat issues. They run fine but are not running at there top end due to heat concerns
Yep. 10 vs 13 GH/sec...? Quite some difference with ample cooling.

i think imma just buy 1 of the usb things and a rasberry pi, leave it and forget it. lol check back once a month and order pizza with the winnings
Thats a good way to look at it ...but even then you might not have enough for a pizza lol
Here's some more food for thought...
Assuming the difficulty doesn't increase too much (it's already climbing pretty fast) and that you're part of a fairly lucky pool (a lot of ifs), at ~300 MH you should see something like 0.01 BTC a day.
That fastest way to get pizza is to use a service that takes BTC (and charges a fee) to buy pizza because you'll have to wait a long time to hit minimum amounts to do money conversion at most exchanges. Now let's say the pizza costs $10 and the fee is $2 @ a rate of $100 per BTC (for simplicity), you'll need 0.12 BTC. That's 12 days at the previous rate to be able to get pizza, so 2 pizzas a month which is not bad.
However, considering that you spent 2 BTC on the hardware you could just buy yourself 16 pizzas to begin with. That's 2 pizzas for the next 8 months.

Granted the question is GPU vs. Eruptor USB, but has anyone considered how fpga(s) stack against the Eruptor USB. I'm actually using fpga(s) because:
1) They're similar to the Eruptor USB at ~ $1 per MH
2) They use more electricity than the Eruptor USB, but not that much compared to GPUs (my Lancelots use 28W compared with GPUs at 100W)
3) And this is the key point for me... fpga(s) can be repurposed (assuming you know how to edit bitstreams) and have more resale value compared to the Eruptor USB.
Unless the Eruptor USB comes down more in price... it's not worth it from my viewpoint because it has no resale value and the amount of time to recover costs is not significantly better than fpga(s).
Anyhow my 2 bitcents...

Hey all.
Thanks for your thoughts. I am tending to agree that the USB asics are not seeming like a particularly smart option. I have decided to go with some more GPUs for now, because as a few of you say, they have more than one use and can be resold after they are no longer any use for mining... and, because of my line of work, i can write them off on tax. Hooray. Haven't really sorted the power situation out. I do have to pay for mine, but i'm sure i can come up with an ingenious plan.
That should keep me mining away for a while until i can perhaps get my hands on a more serious ASIC down the track. Though i do kind of feel like it is now or never to a certain degree. If i finally get an ASIC in a years time say, its feeling like it will be about as profitable as a GPU is now. What so you guys think about that. Will the incresed hashing of the ASIC just end up being balanced out by the difficulty rises?
Cheers

Go with a gpu. Block erupters will take a long time to get your ROI with the predicted difficulty jump. Gpu's can mine scrypt and play video games. Much better investment
+1 - GPU's have more than one use whereas ASIC Miners are made for one thing and one thing only. It is an obvious no brainer if you are making a small investment (<=5K)

Hello.
So i am relatively new to the whole mining game. Coming in at an interesting point in the whole thing it seems. I currently have 4 7970s churning away. I'm looking to invest some more into mining and wondering what people think the wisest next purchase would be considering the imminent onset of the ASIC era. By my calculations, buying more GPUs will give me a higher Hash per dollar spent ratio, but then factoring in power, and ease of use etc, its seeming like getting some of the Block Erupter USBs might be a better choice at this point. I know they are not hugely exciting when compared to whats coming with the bigger units, but i do very much like that they are available now! ... A huge plus in my opinion. What do you guys think? More GPUs or Block Erupter USBs?

GPUs are OK, but eat up a lot of electricity. If you don't pay your own bill, still good enough for a few GH/s.

Agreed. but not really sure how to get my hands on either of those. Any ideas?
id say buy a avalon if you can OR a BFL early preorder
Coinish Calc say you will never make your money back... guess that just about does it then... unless anyone can give me an argument why they are still a good idea?
