苹果A13芯片首次曝光：性能战神，提升巨大！
每年9月，苹果都会发布最新款iPhone。作为旗舰手机，历代iPhone在性能方面几乎一直处于顶尖水平，每年一更新的A系列芯片，配合全新的iOS系统，更是让iPhone的性能发挥到了最大化。
今年秋天，苹果即将发布搭载A13芯片的新iPhone，现在距离苹果秋季发布会越来越近了，苹果A13的性能表现也开始引人关注。
性能得到进一步提升那是肯定的。不过具体提升幅度有多少，达到什么水平，在新手机推出之前我们无法得知，不过外媒Macworld则根据过往数据来进行了一波预测。
Macworld认为，苹果A13芯片会使用台积电7纳米EUV工艺制造，虽然同样是7纳米工艺，但由于技术改进所以性能也有一定提升。他们预测A13芯片的晶体管数量和A12X一样，但有机会升级到3+4的七核心设计，所以性能要比A12X强不少。
具体数字上，Macworld猜测，A13的CPU单核性能可以达到5200分以上，而多核性能有机会达到16000分水平。光是从数字来看，苹果A13芯片的GeekBench 4跑分表现已经超过所有的智能手机芯片（包括A12X）和大部分X86电脑芯片，性能非常彪悍。
至于GPU方面，Macworld表示苹果芯片的GPU性能近年来有放缓的趋势，所以预测A13的GPU性能或许不敌年底推出的高通骁龙8系旗舰。再者苹果芯片的GPU性能可能会受到内存带宽的限制，性能飞跃或许是2020年的事情了。
虽然说是预测，但Macworld的分析算是有理有据，预测数字也比较靠谱，波老师认为结论还算合理。或许对普通消费者来说总会出现「苹果手机不堆硬件」的假象，但实际上苹果手机却是行业中最注重性能的产品，他们的SoC性能一直都是行业顶尖。
实际上伴随着iPad Pro 2018出现的A12X芯片已经非常强悍，无论是CPU性能还是GPU性能均一骑绝尘。可想而知，以苹果的芯片研发实力通过堆料打造出一款性能超群的SoC根本不是问题，唯一的考虑因素只有成本和商业利益而已。
值得一提的是，苹果A13芯片还将大幅提升AI性能。全新的神经网络引擎会让苹果A13芯片的AI性能在A12仿生的基础上再增加3-5倍。通过强大的算力，我们可以获得优秀的拍照效果，同时还能为Siri语音助手带来更多用户体验出色的新功能。
