主流显卡核心的挖矿效率简要对比:

ATI系列显卡
HD 6570 | 速率 78.5 MHash/S
HD 6670 | 速率 96.9 MHash/S
HD 6750 | 速率 156.3 MHash/S
HD 6770 | 速率 182.3 MHash/S
HD 6790 | 速率 182.5 MHash/S
HD 5870 | 速率 343.2 MHash/S
HD 6950 | 速率 299.3 MHash/S
HD 6970 | 速率 355.1 MHash/S
HD 6990 | 速率 714.8 MHash/S
HD 7950 | 速率 453.7 MHash/S
HD 7970 | 速率 566.2 MHash/S
HD 7990 | 速率 1073.5 MHash/S
NVIDIA系列显卡
GTX 285 | 速率 56.1 MHash/S
GTX 460 | 速率 71.1 MHash/S
GTX 570 | 速率 124.2 MHash/S
GTX TITAN | 速率 302.4 MHash/S

在挖矿的效率对比上,同样价格的N系列显卡完全比不上A系列显卡,这是由显卡的设计架构决定的。
