Why does Avalon have a lead time of DECEMBER?

Terrahash is listed twice

How is your ROI actually calculated?

hard to explain, link is under the chart.  Basically looking at 1gh/day at todays difficulty, then project it into the future based on past difficulty raises.

Why does Avalon have a lead time of DECEMBER?

I may have seen that somewhere, do you have a better/more current link to an estimate?

Terrahash is listed twice

One is with your chips, one is their chips.

Kncminer is Sept not Oct.. delivery , you should consider all in $ or btc... not some btc and others in $

I think they say mid Sept they'll start taking orders, so by the time the first orders are received it'll be so near the end of the month it would mess up roi to say Sept.

The price listed is the price asked by the manufacturer.  I'd rather let people know what currency they are accepting.  The GH/BTC gives plenty of information about comparison, imo.

there are still only usb asicminer block erupters in the table, not the big ones, which do 12-13 GH/s with power consumption of 120W and price 49.99 BTC

Ok I'll take those stats, do you have a link?

Note - the year/hr calc is wrong.  You have 24 * 356...

Totally unnecessary. It's posted as a spreadsheet on google docs....

Great way to get a general understanding of whats proposed for the future of ASIC's

Thanks, many people seem to think I'm saying this is all set in stone

May 25:
Cleaned Spreadsheet, fixed ROI reference tags, added date and BTC exchange rates for currencies listed in the chart.

The KnCMiner Mars 6gh/s @ 2795 USD is still missing https://www.kncminer.com/products/mars

[desper]

This very good!

OK, so your "1 year ROI" calculation is more like "number of bitcoins mined in a year" given different average difficulty increases every 2 weeks (and your sheet 2 shows historical data for the difficulty increases).

I think "number of bitcoins mined in a year" would be a better name for this calculation.

You then need to subtract the yearly electricity cost and the original cost of the miner from the "number of bitcoins mined in a year" to get the "Profit" which will often be less than zero (i.e. a loss)

The ROI will then be "Profit" / "original cost of the miner" and will be a percentage.

Now that I downloaded your spreadsheet to Excel, I realized your "1 year ROI" is actually "Profit" as I described above. Dividing this by the original price to get the ROI is very instructive.
Basically, if you think difficulty will rise slowly, KNC miners look best, but if you think difficulty will rise faster, evilscoop's unit looks best (assuming the Lead time (maybe should be called "Delivery date") you give). This makes sense, obviously.

BTW, from the Excel file I downloaded, it seems you could make much greater use of formulas (VLOOKUP etc) to ease updating of this spreadsheet. If you want help with this, drop me a PM. (I'm familiar with Excel, but not so much, Google spreadsheet).

Yeah that does sound confusing, I was looking for a new name for that column.

Just in case anyone missed it:

Orange:  untested products, never shipped. 
Red:  those that will not make more bitcoin than you spend on them in one year.
Green:  has product ready to ship with positive 1 year return on investment

Tough time to be a miner.

[alibert]

I dont understand the colors. Avalon is shipping (Batch 1+2). BFL isnt. ASICMiner is also shipping. Or did I miss anything?

Oh, and those are missing https://bitcointalk.org/index.php?topic=204030.0

How in the world do they figure an Avalon won't be profitable after a year?    

Whoever made this is crazy lol...

[forevernoob]

Well it's not looking good...

Not a single green one in the list. Unless I'm color blind

Thanks, I knew I was missing an important one, I guess I hadn't distinguished between those and the other blades.

Avalon is shipping chips, which will have a big effect on the list once they start coming in.  The 63GH machine, however, isn't being shipped.

ASICMiner is shipping.  It's the ROI that's a problem.

If you own an Avalon that's great, it's going to make you a bundle.  If you have to buy one as soon as possible and get it by December the difficulty is going to kill your return.

I think I'm going to say this on the main page...  This chart is NOT saying that your machine will never be profitable if you come out with negative BTC in a year.  It is saying that you may as well have bought BTC and held them.

Well it's not looking good...

Not a single green one in the list. Unless I'm color blind  

Hehe..  yeah, but that could easily change in June/July.

Edit - Well I changed my mind on the time for Avalon's 63GH.  Sorry Avalon!  Think this could be closer.  I could just as easily put June, but at the end of the month I'll be changing a couple other people's so it'll be more even.

I don't understand your Avalon entry. Avalon batch #1 finished shipping a while ago. Avalon batch #2 is currently being shipped. Avalon batch #3 will ship in a month or two.

FCTaiChi   thanks for putting this information together

[ashaw596]

The assebly cost for the evilscoop stuff is for K16 board btw not a K64 board. (I looked it because the ROI seemed incredibly high).
