Where are the 28nm FPGAs?

[Epicblood]

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)

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 em
I 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

all depends on price of the pcb, I get the chips for half 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?

What are the hash rates for these 28nm FPGA? tks

We won't know for sure until someone buys them and works with them.

The virtex is about 20-30% faster than the kintex.
not exactly sure, I have no experience in making a PCB, I'm looking into that now myself

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.

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?

[Herbalconfusion]

<----willing to invest in return for a finished product, 

[pizza]

what we need now is for someone to create a pcb design before pricing is even spoken of.

Been saying this the whole time xD
someone makes me one I can get an FPGA togethor

BUMP FOR THIS ^^ SOMEONE!!!

<-- Also interested in investing in the dev effort in exchange for finished units.

If all you investors want to set up a bounty for a pcb design using the artix-7, kintex-7, and vertex-7 (3 diff boards) that would be great
or if you send however much BTC you wanna offer for this to me, I'll set up the bounty, either way that's all I need to start work on a 28nm mining FPGA

The size of the die inside the chip is smaller, or more logic/LUT's can be fit in the same die area as the previous generation.

The actual package might or might not be smaller. The smaller FPGA's in the Artix family is available in 10x10mm packages (0.5 mm pitch), even though high capacity Artix FPGA's more suited to mining is only available in bigger packages, 19x19mm being the smallest. However, many hobbyist/PCB designers prefer larger packages which have pins which can be be soldered by hand (some hard core hobbyist can solder BGA's using other heating devices)

One of my friends and I are working on designing the PCB (he knows how to do it an stuff) so once I get that, I will be adapting the opensource FPGA miner to run on it (we will be using 2x Atrix-7)
will make a thread in proj dev to keep you all updated.

I just updated the repo with a DSP48E1 design, for Kintex 7.  400MH/s using 80% of the DSPs, and ~25% of random logic.  I don't have an Artix-7 to port to, but I think they also have DSP48E1's.  I plan to start revamping the code base to better support multi-core designs and standardize the communication modules.  Hope to get my Kintex up to at least 1GH/s by throwing in two regular hashing cores.
