新iPad的亮点除了屏幕，还有它的A5X芯片。专业的芯片网站近日公布了A5X芯片的多晶硅模具照片，先撇开A5X的性能有何提升不说，光是从体积上来看，A5X相对A4、A5芯片增大了不少。

具体地，苹果的A4处理器体积有53.3毫米²，经历了两年的更新换代，A5X芯片有165毫米²，体积足足增大了310%。苹果的这三代处理器均是采用45nm工艺。因此，要用相同的工艺塞入更多的性能，体积自然不会缩小。我们之间来看这三块处理器的对比图（已缩放到相对的实际大小）。

苹果A4、A5、A5X处理器模具图对比 A4多晶硅模具=7.3mm x 7.3mm

苹果A4、A5、A5X处理器模具图对比 A5多晶硅模具=10.09mm x 12.15mm

A5X多晶硅模具=12.90mm x 12.79mm
