how many hash could this chips run? 22nm should be fast and low cost power consumption, lets hope the price is reasonable lol .........  |

Any guess on hash rates right now would be pure speculation based solely on the chips specs. Can I say they will be better than Spartan6's? Most certainly. Will they be worth the price? I guess we will find out, huh? |

Wild speculation: They can probably fit 5 hashing cores and run faster than a spartan 6...maybe 1 to 2 gh/s in total. Could be way off. Hard to guess about the power usage. They might be worth it, if they're cheap and the btc price stays high. |

The development board is $13k and includes the software as well to do a complete design. Regarding the cost of silicon, that of course depends on your volumes and schedule. Unit pricing in $3190. Please let me know your volumes and I can provide a budgetary quote.
For my records, if you can provide me with your company name and website, I would appreciate it.
Regards,
Ken Achronix's response on price points. |

This chip is not going to hash well. For each 10 LUTs there is only two 2bit hardware adders with carry chains. Ordinary LUTs don't have carry chains. In Spartan 6 at least half of LUTs had carry chains, and this is very important to build fast adders, and those adders comsumes most of the logic resourses when used in SHA256 algorithm... Cheaper and better (in term of price/performance ratio) should be Atrix7's.

Under development Modular UPGRADEABLE Miner (MUM). Looking for investors.
Changing one PCB with screwdriver and you have brand new miner in hand... Plug&Play, scalable from one module to thousands.

hi guys,
i ve discussed with one of their representative and he said that basically it would be possible to run 7 instances of the spartan equivalent instances in their chip.beside that the clock speed is around 600/700mhz so it would get better speed than the spartan6(wich is running at 50mhz if i m not wrong)
so basically he said the speed of this fgpa could be X87 times better than the spartan6
any of you who have technical background in fgpa can confirm this?
and another question, is there any chips similar to the achronix one with the other competitors,altera,xylinx or lattice?
thank you guys

so it would get better speed than the spartan6(wich is running at 50mhz if i m not wrong) 200mhz is the current figure (without manual placement). beside that the clock speed is around 600/700mhz It's unlikely the rep meant 600/700mhz for the hashing designs; he probably meant that the fabric itself can run at 600/700mhz. In other words, the registers and block ram will run at 700mhz, but any complex logic will run much slower. For reference, the Kintex 7 fabric runs around 500mhz, but that doesn't mean a CLB based miner would run at 500mhz (more like 300). basically it would be possible to run 7 instances of the spartan equivalent instances in their chip Looking at just the LUT count, I would agree with the rep, and I imagine they did the same (look at the LUT count). However, as Dexter770221 mentioned, performance could be much worse if their FPGAs are sparse in terms of carry chains. At $3k per chip, I don't personally see a good performance/$ here. It just sounds a lot like a Virtex/Stratix chip. |

And propably lack of free software. I didn't see any free oferings from them. And tools like that costs 1000's of $. Is their place and route software expensive (not counting 3rd party synthesis and timing analysis tools) |

Is their place and route software expensive (not counting 3rd party synthesis and timing analysis tools) It's included in their dev kit, which is $13000. Other vendors charge about 3 grand for their software, the Achronix FPGA costs about 3 grand - thus, I'd say, Achronix charges you more for the software, basically 9 grand or so. Do the math. |

one of their representative in europe said me that the software will be free for now
the only issue is that their chips have not finished all the due tests so you can have the chips but you will be the one who will test it with all the bugs etc.
so this is not ideal fgpa to use right not ,not only the dev board +chip is expensive but because there is lack of docs because it s a new product(first people have just start to dev on the chips last end feb/beginning march)
i think kintex7 could be more interesting as multiple instances equivalent to spartan 6 could be implemented.
does any one have the kintex7 and could do the implementation to confirm this?
i could be interested in several if they give 2/3 giga per chips and even hire soemone to work on pcb for this for big quantity
thanks

The XC7K480T would probably do that, but I would assume that it's not cheap... |
