Re: [2018-02-12]Bitmain To Release Ethereum ASIC Miner F3 With 72Gb DDR3 Dram In Q2
650mh/s with 72 DDR3 memory? Its Simply Nonsense, and I tell u why:
So what we know is the RX 580 has 192Gb/s bandwidth and able to perform ~30mh/s
Well if we choose the best DDR3 memory with 1866Mhz (1866000000 Hz) then we can calculate 1 ddr3 memo chips's bandwidth. It's has a 64bit lane so 1866000000*64*8/1024/1024/1024=14.9 GB/s this is 1 DDr3 memo chip's bandwidth.
14.9*72=1074 Gb/s this is the total memory bandwidth with 72 ddr3 chip. So 1074/192*30=~168 Mh/s this could be the maximum eth mining performance with 72 ddr3 chips. Everything else is bullshit.

You are talking about GPU for gaming and not full system design to mine ETH. Think about optimisation in code and so one...
Yes, this is what I was thinking as well. A few people in this thread have said it would be impossible for memory at that speed to hash at a rate higher than what the video cards can currently do, but my thought was that if you had a dedicated ASIC chip designed to do nothing but that math well, connected directly to memory, all highly optimized for nothing but that math, then it just might be possible. But, this is all speculation so far. It would not surprise me if Bitmain does release this. I remember seeing that Samsung was getting into supplying chips, could they be supplying the memory chips for this new Bitmain asic perhaps? It's all very interesting :-)
