<----willing to invest in return for a finished product, 
If I understand this correctly, since the 28nm chips is small we can be place more of them into the pcb board? what we need
now is the Price of this pcb board and the Hash rates it can produce?

Could this be turned in with the EasyPath 7, and mass produce a set of EasyPath Chips?
At least the hardcopy results at 45nm were not all that impressive— a bit better than the FPGAs, but you lose all the reconfigurability. I'm doubtful that EasyPath 7 will be enough of an improvement (plus the lead time!) to really be attractive. My thinking here is that 28nm FPGAs can have short lead times and they're reconfigurable... and this may make up for modest MH/$ and and MH/j disadvantages compares to 100nm+ mining asics. Lets get this going, I'm sure a bunch of us could pool money together and get a group buy going on components and making the fpgas.
lol just get me a pcb layout and I can start making emI could sell em pretty cheap too, cause like I said, I get the chips discounted/free
i ve asked twice for a quotation you still did nt reply me and playing around
as i told you i could need 500 of each ,need to know the price
I estimate about $100- 200 per FPGA (kintex-7)
Virtex-7 would be maybe 25-50 more
if enough people want it so I can order pcb in bulk, it'll will be even cheaper
The vertex 7 is only that more expensive, but would do what 4x the kintex? Also what would be needed for the pcb to get that going? What sort of controllers are we looking at?
not exactly sure, I have no experience in making a PCB, I'm looking into that now myself
What are the hash rates for these 28nm FPGA? tks
We won't know for sure until someone buys them and works with them.

I think Artix-7 would be the best one/most cost efficient to mine BTC on, Virtex is a bit of overkill, and a lot more expensive.
Zynq would probably be amazing as well though (I think)

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.
Have you tried a Virtex-7? Also what sort of Kintex 7 did you try it on.

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

Just need a simple board.

Luke will code a driver for just about anything into bfgminer if you send him a unit.

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.

Wich one did you get?
Wich price?
as i m interested in mass prod so if you have anything to share please pm thanks

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).
