Default 至少理论上最强:新一代FirePro性能首曝

架构差异让AMD南方群岛在浮点性能上大大超越NVIDIA开普勒,新一代专业显卡之争上FirePro W系列看起来似乎也胜过了Quadro K系列,至少理论性能如此。今天我们又看到了AMD官方的一组性能对比幻灯片。FirePro W9000的单精度浮点性能已经达到4TFlops,双精度也高达1TFlops,相比之下Quadro K5000单精度仅为2.1TFlops,双精度的官方未公布而第三方消息来源指出还不到0.1TFlops。要知道,上代费米时代还能跑到0.6TFlops,退步非常明显。而且上市时间上AMD也居于领先,FirePro W系列已经开始陆续出货了,Quadro K5000则要等到十月份,GK110核心更是不知何时。顺便说一句,Intel Xeon Phi的计算性能据说已经达到单精度2TFlops、双精度1TFlops,非常值得期待,只不过架构迥然不同而已。虽然
