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.

Well, you've got the right idea but the wrong numbers. Rx 580 @2Ghz has 256GB/s of bandwidth not 192 (R9 380 @1.5Ghz has 192). ddr3 is available in x8 and x16, and since x16 has twice the bandwidth, that's likely what Bitmain will use. Going with those numbers I come up with 250-300Mh/s.
Indeed, you are right with the bandwidth of RX 580, I found that 192gb/s from a shitty site, but your formula is wrong too. I made 2 mistakes, the first is the bad bandwidth, the second is that I used 64bit bitrate for 1 chip but 1 chip has just maximum 16 bit/clock , this is refers to the x16 (or x8 or x4), 64bit is the bitrate of the full DDR3 stick with many memo chips. So we have 3x32 1Gbit chips. Let me recalculate this: 1.866*16*32*3/8/256*30=~39.3 Mh/s

168Mh/s @ 500W? There is no point in buying that asic...
"hash will be 200-220 MH / s. Price - $ 2500- $ 3000."

The worlds largest producer of mining equipment Bitmain is working on the creation of Antminer F3 - ASIC-miner for the second largest capitalization of crypto currency Ethereum. This is reported by IBTimes referring to local technology publications. This is reported by Ib Times.
As the source notes, Antminer F3 will be equipped with three motherboards in each of which will be installed on six devices for the Ethereum mining. Each board will have 32 DDR3 RAM modules with a capacity of 1 GB. According to a number of sources, the hash of the device will be 200-220 MH / s, but with the specified specifications, this figure can be expected to be higher
It is assumed that the production of new equipment for the production of ETH will begin at the end of this month. In the world market the novelty will appear approximately in II-III quarter of this year. The price of Antminer F3 will be set at $ 2500- $ 3000.
Well, actually that's numbers can be valids, because if you do the math with 32 1Gbit ddr3 1866 module*3 (4GB per board) then 32*3*14.9/192*30=~223.5Mh/s (=~7x RX 580).
