现在比特币（BTC）、狗狗币（DOGE）、以太坊（ETH）等加密货币经常成为头条新闻。随着加密货币的暴涨，与过去几年相比挖矿盈利能力大幅上升，很多人加入显卡挖矿大军。说到显卡挖矿，市场上的各品牌和型号的显卡挖矿算力相比如何呢？其相应的挖矿收益表又是怎样的？本文将为您揭晓。
由于现在显卡挖矿投入产出比最高的是以太坊，所以本文以以太坊ETH为例。所有测试都是基于台式电脑，CPU为英特尔Core i9-9900K，主板为 MSI MEG Z390 ACE， 2x16GB 海盗船DDR4-3600内存， 2T XPG M.2 固态硬盘, 海韵850W 80 Plus 白金认证电源。

表中算力为0表示不适用于ETH挖矿单可用于其他小币种挖掘，回本天数指挖矿获利可以覆盖显卡费用所用的时间。
选择显卡用于挖矿不仅要看算力还要考虑显卡价格和功耗，这样才能达到最大投入产出比。
