Title: FPGA VCU1525 1900 mh/s Ethereum Post by: markiz73 on June 10, 2018, 10:41:42 AM Today i show you what i know so far about FPGA's and their possible mining capabilities.
As shown in the video, their hashrates on Ethereum for example could be enormous! ASIC's are nothing compared to these possible hashrates. https://s8.hostingkartinok.com/uploads/images/2018/06/321403a480c8288026ebc1678b89a102.png (https://hostingkartinok.com/show-image.php?id=321403a480c8288026ebc1678b89a102) See https://www.youtube.com/watch?v=x9DJ18y8LcI FPGA VCU1525 60 x R580 1900 mh/s 1900 mh/s 225W 6000W 4000-5000$ 18000$ Title: Re: FPGA VCU1525 1900 mh/s Ethereum Post by: vuli1 on June 10, 2018, 12:23:10 PM how many threads/topics does VCU 1525 need?

one comment posted about that video Quote There's something wrong with the shown hashrate based on the available memory bandwidth for this Xilinx FPGA card. We know each hash of ETH requires 8192 bytes of memory access (ie. DAG access per hash is done by a 64 iteration loop with each iteration accessing 128 bytes of the DAG, thus 128 bytes x 64 iterations = 8192 bytes per hash). Now a hashrate of 1.9 GH/s means it would require around 15564.8 gigabytes per second of memory bandwidth. In terms of bits this means that hashrate requires around 124518.4 gigabits per second. This Xilinx card comes with 4x DDR4 DIMMS, with each DIMM providing a 64 bit data bus, thus the 4x DIMMS provide a total data bus width of 256 bits. The required memory bandwidth of 124518.4 gigabits per second (to get the 1.9 GH/s hashrate) means the DD4 DIMM module must have a speed per data pin of around 486.4 GHz (equivalently 486400 MHz). But there doesn't exist any DDR4 DIMM with data pin speeds which reach the needed 486.4 GHz. So the DDR4 DIMMs used by this Xilinx card can't even provide the required memory bandwith to give the hashrate shown. 18 Title: Re: FPGA VCU1525 1900 mh/s Ethereum Post by: TwisterPipister on June 10, 2018, 08:05:07 PM Video has been disproved, is clickbait nonsense. Ignore. When I have heard about that miner I started thinking about selling my farms, I was hoping that it is fake, if it is fake then it is a great news :) Title: Re: FPGA VCU1525 1900 mh/s Ethereum Post by: senseless on June 10, 2018, 08:32:39 PM Video has been disproved, is clickbait nonsense. Ignore. This. The video is total BS. And, I'm actively selling these boards -- that should tell you something.

Cryptonight - v1 14Kh / s 150W Lyra2z 20.5Mh / s 150W Is it possible to mine the ETH algorithm on it and what will the performance be?

Cryptonight - v1 14Kh / s 150W Lyra2z 20.5Mh / s 150W Is it possible to mine the ETH algorithm on it and what will the performance be? It should possible (if somebody designs bitsreams) because the board has 16GB of mem. Perf wise, I have no clue.

But I don't think there are any development boards for those yet.
