Let's do a comparison:
I'm sure I'm missing some, who is shipping now or shipping in October that is in the mid to 100GH hashing range?
1. BB Fury: 40/60/80 GH $1000 (shipping oct)
2. BFL : 50GH $4,600 (hahahah)
3. KNC : 100GH $2,000 (no longer available/shipping oct)
4. Tarrahash: 18GH $900 (sold out and are these shipping?)
5. Erupter blade 10GH $650 (shipping now)
too expensive
$1000 for 40-80 ghash isn't even worth risking.
Why is this overpriced? Megabigpower charges $8000 for an October delivery 400 GH/s kit. This looks like it will only be $5000-$6000 for the same thing.
It's similar in price to HashFast's 400GH/s miner, but that won't ship till the last week of October and they have yet to demonstrate that they have working hardware.
Here are my comparions for a US customer. I've listed the total amount including shipping for a 400GH/s device that will be delivered in October:
1. KNC Jupiter 400GH/s (sept/oct order that will likely ship in oct) $7,131.80
2. HashFast Baby Jet 400GH/s (ships oct 21-28) $5,769.57 (bitcoins only)
3. BitFury 16-board kit 400GH/s (oct delivery from megabigpower) $8,000.00
4. BFL (nothing available)
5. ASIC Miner (nothing available thats even remotely competitive)
6. Avalon (nothing available)
7. Bitburner Fury 320-640GH/s early oct $7,475.00
As you can see the price is very competitive especially when you take the following into account:
- You can't order a KNC Jupiter for October delivery anymore. They are already sold out. They have no proof of working machines yet (as far as I know) so it wouldn't be too surprising if they don't ship on time.
- The HashFast Baby Jet won't ship until the very end of October. They also don't have proof of working machines either and could likely be delayed. I think their tape out was scheduled to be Aug 31 or so which is a very short time to have working machines.
- The bitfury chips actually exist and are working.
- The Bitburner Fury machine is the only one that seems like it will be easily overclockable. I would be surprised iif it isn't capable of 500-600GH/s. The HashFast may be overclockable too but no one knows yet.
Disclaimer: I have KNC, HashFast, BitFury (from megabigpower), Bitburner Fury, and BFL machines on order
