10.4日苹果发布会发布iPhone 4S,然后苹果联合创始人史蒂夫•乔布斯永远的离开了这个世界,为了缅怀这位伟大的艺术家、创新之父、我们永远的教主, iPhone 4S被众多果粉解读为”iPhone for Steve”, 那么这款iPhone 4S到底都有哪些方面做了改进呢?

第二部分: GPU图形处理器

苹果A4处理器中集成的是Imagination Technologies PowerVR SGX 535,在iPhone4S中则升级为PowerVR SGX 543MP2。SGX 543 采用模块化设计, 单个核心的峰值浮点性能就是SGX 535的两倍,A5 CPU使用的是双核心版本。在iPad2发布的时候号称性能有9倍提升,在iPhone4S发布的时候号称性能有7倍提升,这里可能考虑电池用量的问题,性能有所下降。

下面我们来看一下使用GLBenchmark 2.1.0 测试的结果。下面是iPhone4和iPhone4S使用GLB测试的结果对比表:
