        苹果官网资料显示:
    配备四核图形处理器的 A5X 芯片能够驾驭 4 倍于 iPad 2 的像素数量，同时保持令 iPad 著称于世的平稳与流畅。尽管魅力得到显著提升，但全新 iPad 依然拥有惊人的 10 小时电池使用时间。
苹果CEO蒂姆·库克称:
新一代iPad配备A5X处理器，性能为NVIDIA Tegra四核处理器的4倍。
So.............:::
2048×1536分辨率Retina display搭载 A5X双核处理器 :
此次发布的新iPad未搭载四核A6处理器，要在支持2048×1536分辨率情况下提高整机性能并达到不俗的显示效果，就要强化GPU图像处理器。

New ipad "iPad3"  A5X芯片组  双核cpu四核GPU,GPU由前代的PowerVR SGX543MP2升级为PowerVR  SGX543MP4。苹果方面宣称A5X的 GPU效能是前代A5的2倍，更是NVIDIA的 Tegra 3芯片组的4倍。实际运行效率远超其标称数值更高的竞争对手，却是一个不争的事实。如果苹果的A5X已经足够支撑效能的需求，那么NVIDIA包含4核cpu与8核GPU的芯片组是否显得哗众取宠？ 总结
