Some crypto miners are accumulating so much wealth that they are looking into building their own chips and hardware to mine even harder than what you can buy commercially from Nvidia.
- latchkey 5y agoNot for ETH. ethash is memory controller bound, not chip bound. This is why older generation GPUs are higher ROI than buying latest and greatest.
- 15155 5y agoWhy would Bitmain be releasing the Antminer E9 if it has no benefit over GPU? Ethash is bounded by memory bandwidth, sure, which is why HBM-based ASICs and FPGAs will be better than non-HBM GPUs in almost every case for mining ETH.
- latchkey 5y agoIt isn't just hash/watt, it is $/hash. HBM is expensive. This is also why the bitmain boxes only come with 6gb. The dag will eventually grow and render them useless, just like we saw with 4gb gpus... The ethash asic's are not that much better than GPUs as they are all bound by memory controller speed. Even with faster memory, the gate is always how fast you can move through the DAG. That red circle is the issue... https://www.vijaypradeep.com/blog/2017-04-28-ethereums-memory-hardness-explained https://www.vijaypradeep.com/blog/2017-04-28-ethereums-memor... The only benefit of the bitmain boxes is that they are plug and play. You buy one box, stick it on the shelf, plug it in and that's it. GPUs are significantly more difficult to tune and run, especially at large scale. The ROI on these boxes is terrible... imaging you buy one and it burns out... zero chance for repairs on any sane timeline. Why does bitmain sell it? Easy money for a company that has a long history of ethics violations. When I was buying L3+'s directly from bitmain, they'd come clearly used.
