searched a whole little to debunk this shit article with shitty ads all around.
Option 1: Design a High Memory Bandwidth FPGA/ASIC Board
Looking at the RX 470, we can do some quick math ($175 / (211 GB/s) ) to see that it costs $0.82 per GB/s. Compared to a single GDDR5 chip (e.g. Micron EDW4032BABG), which costs $6.83 and has a bandwidth of 24 GB/s, we can do better at $0.28 per GB/s. So, if we can build custom chip (either ASIC or FPGA) than can interface with 9 GDDR5 chips, we’ll have a memory bandwidth of 216 GB/s at a price of $61.47. This still isn’t a finished mining product, since we need a FPGA or ASIC memory controller, circuit board, & support electronics. If the shipped final assembly (adding additional parts, processes, testing, & logistics) costs less than the RX 470 (only $175), then the custom board will beat the GPU based card. That is, until a faster, more efficient, cheaper graphics card comes to market. For instance HBM graphics cards cards are already available. But, if you find low cost, off-the-shelf, FPGA or ASIC chips with 5-10 DDR or HBM memory controllers, or your company is experienced in building custom high memory bandwidth ASIC solutions, you may be able to beat out off-the-shelf hardware. But, if in this situation, you should probably change your business model and build graphics cards instead, since that’s already a huge market.
even DDR5 memory is overwhelmed and i own 2 970s and they are shit at mining 9mh/s i think max for a 4gb? let's do some african math "because i'm from africa" 72gb/4gb = 18
gb * 9mh/s = 162mh/s for this miner and don't forget the stuff sited in the quote above.
