I'm surprised to not see some small mining devices based on artix7. I would expect their power usage to be basically competitive with Avalon... and the retaskability of FPGA is worth paying a bit of a premium for... Seems odd to me that there hasn't been any motion in that direction.

Group buy? That be a project for DIY no? |

Well— for some level of DIY— someone like RPH who feels at home skillet reflowing $150 FPGAs might consider it one.  I'm mostly surprised that none of the companies making S6LX150 devices (ztex, x6500, etc.) have produced a device based on 28nm FPGAs for sale. Availability has been good, they could have even beaten Avalon to market... and at the moment there is so much demand for ASICs you'd think you could make some good sales with something that was at least ASIC-competitive but with a lower time to market. |

artixminer.com based in Kenya in 5...4...3... Ok, so we are another Bitcoin miner outfit coming out of nowhere, but we are not a scam. We will not take any money till we tell you we're ready, with our product line that is.
My partner and I have been mining bitcoins for several months now and we came up with the idea of Artix-based miners when we saw what the ASIC guys were NOT doing.

Anybody done the numbers to find out how many MH/s these would get? If you could get >1 GH per chip it might be worth looking into it.

How much does the Atrix7 cost? i.e. the XC7A200T or XC7A100T

you'd think you could make some good sales with something that was at least ASIC-competitive but with a lower time to market. Rewind the clock a few months, when ASICs were expected to ship within weeks, and you'll see why most FPGA based companies probably backed out of the market. Beyond that, FPGAs are still at least twice as expensive as the current ASIC offerings and four times the power consumption. Development of a new FPGA based miner would take weeks before shipping, if the firmware were even ready for it. If you want to blame anyone, blame all the ASIC companies that poisoned the market and failed to deliver. Of course, I continue to tinker with my FPGA designs in case some new fruit is found. I now have 400MH/s firmware for the Kintex 7 chips running at ~15W. FPGAs can also now do vanitygen. |

Quote from Xilinx :
"
qty of 1k units for the Smallest and slowest Artix200 is around 110/120 USD
The biggest and fastest Artix ( The 350T ) is around 350 USD ( for 1k units )

So it beats the Spartan since you get more Mh/s/$. |

How much is the Kintex 7? |

You can't beat the re-purposing ability of FPGA technology, I'm fairly sure that new ASIC customers will be terrified of their ROI due to the various acts of Satoshi that could screw it up for them. |

Not sure there'd really be any point to anyone developing them, since BFL have been shipping next month for about the last half-year or so.

What the fuck are you talking about? speak in code so that no one understands you? |

I get discounted chips from xilinx, so if someone gives me a PCB design that would work with any of the 7 series chips, I can order some up and make em.
only thing is IDK how to code in verilog much, so you'll have to use the opensource FPGA miner
EDIT: I have put together FPGAs before using Xilinx chips and have the tools required (not for mass production).

The cheapest XC7A200T I can get in singles is $242.5/chip
I just don't have the cash to drop for $250/chip to just test with.

Replied to your PM, like I told him, my dad is a higher up in Xilinx so I get any/all of the chips at a nice discount  |

Could this be turned in with the EasyPath 7, and mass produce a set of EasyPath Chips? Phil |
