btcfpga does not have a terahash machine, that is the only problem, but in terms of price they are the best.

is there any other brand that is better?

Yes, at least one (not including our own project yet because of longer delivery time).

If you are talking ASIC then as no-one has delivered anything yet, it is a little hard to say!

I think it's a no brainer...

I am going to place my ASIC order with BTCFPGA.

  • Tom is very transparent when it comes to his business and the upcoming ASIC.
  • He is around to answer questions and for product support daily.
  • But the main reason of why this is a no brainer, BTCFPGA out produces BFL on a $/gH basis, and that to me is a VERY big deal!

I am really glad I didn't order from BFL!

Actually, I'm a bit off on these numbers... it seems BFL also made an announcement on the 29th here: https://forums.butterflylabs.com/content.php/117-Announcement-BFL-ASIC-Release-specifications

BFL's stats:
BitForce Jalapeno - 4.5gh/s @ 4.5w
BitForce Single SC - 60 GH/s @ 60w
BitForce MiniRig SC - 1,500 GH/s @ 1,500w

can you learn how to divide properly?

if 1 gigahash = 0.0234 cents, then you're literally fakking saying that the jalapeno only costs 0.0234 x 4.5 gigahash = $0.1053 cents

what you're looking for is megahash per second

so 1 jalapeno = 4.5 gigahash or 4,500 megahash divided by 163(unit + shipping). 163/4500 = $0.036 cents per megahash

single = 60 gigahash or 60,000 megahash divided by 1333 = $0.022 cents per megahash

minirig = 1.5 terahash/1,500 gigahash/1,500,000 megahash divided by 29,899 = $0.019 cents

NOW FOR BTCFPGA's 54 gigahash machine, $1,100 w/ s/h
54 g or 54,000 megahash divdided by 1,100 = $0.020 cents

to match the minirig, you would have to buy 28 units of the above.

28 units x 54 gigahash = 1.512 terahash = $29,932 to 30k even

PLUS you would have to buy several multiple USB hubs to connect 28 computers to 1 computer, probably another 3-5 k right there.

I graduated 4th grade bro, I know how to divide. Can you learn to take a step back and think for a second instead of just automatically assuming I am wrong because I didn't calculate the numbers in the format that you think they should be calculated in?

You are regurgitating the same information in my post but in a different format. I suppose I didn't explain myself properly.... You are comparing the cost per gH and I was comparing the gH per 1USD$

If I would have seen the announcement BFL made before I made the post, you would see that you could plug those numbers in to proof the numbers you got, but because of the announcement that I hadn't seen yet, my numbers are wrong, not because I don't know how to divide.

PS:
3.5/149= 0.023489932885906
etc.

it's about the cost of EACH MEGAHASH

stop doing drugs over there you mothereffing brat

if you're trying to figure out the cost of each gigahash then you just need to multiply what i wrote by 1000

SO MOTHEREFFING LITERALLY BECAUSE YOUR ASS CANNOT COMPREHEND THIS, 1 gigahash produced by a jalapeno costs $36.2 dollars and the max total of 4.5 gigahash costs exactly $163

I explained to you clearly in my reply how I got my numbers and why they are correct, as are yours....

You are doing your numbers in $ per gH
I was doing mine in gH per ONE US DOLLAR

Each way of doing it is correct and shows the same information, it is really not that complicated. You are either a troll or a few clowns short of a circus. Either way, I'm not going to waste anymore energy trying to explain this to you because you are clearly mentally challenged.

right you need to really label your results there chum

doing what you just did up there, which is 4.5/163 = 0.027 (you need to insert the word gigahash here) or 27 megahash PER dollar

Are you concerned that the very clear and unambiguous labels came before the numbers instead of after?
