  前段时间毅力号登陆火星,可能大家觉得,如此高科技的产品,肯定搭载了速度非常快的处理器。恰恰相反,毅力号搭载的处理器却是20多年前的产品。毅力号搭载了定制的PowerPC 750处理器,单颗价格高达20万美元。

  价格贵并不是因为性能,而是因为其抗辐射、抗寒冷的特性。其可以在零下125℃的环境下正常工作,毕竟火星的环境要恶劣很多。性能方面,PowerPC 750肯定无法和现代的处理器相比,毕竟1998年发布的G3 iMac也是采用了这颗处理器,当然不是定制款。


毅力号
PowerPC 750

  之所以选择老旧的处理器,主要原因在于老旧处理器更加可靠成熟。火星探测器比较特殊,需要长时间稳定的运行,速度是其次。而且毅力号并不需要太强大的算力,在这方面,PowerPC 750完全可以胜任。
