  [AdminSo资讯]苹果营销主管PhilSchiller和芯片制造工程师AnandShimp,日前在接受外媒采访当中谈到新款iPhone11,iPhone11Pro和iPhone11ProMax中采用的A13仿生芯片。

  A13仿生芯片内建85亿个晶体管,数量比A12芯片69亿个晶体管增加约23%。A13仿生芯片CPU部分采用六核设计,有两个名为Lightning的2.66GHz高性能核心和四个名为Thunder的高效核心。A13仿生芯片GPU部分采用四核图形处理器。另外,A13仿生芯片还有用于机器学习的八核神经引擎,每秒可进行一万亿次运算。和A12芯片相比,所有主要组件(包括CPU,GPU和神经引擎)性能提升高达20%,功耗效率比A12芯片高出30%。

  苹果营销主管PhilSchiller表示,苹果已经增强了iOS13文本到语音功能,这样就有了更多的自然语言处理,而这一切都是通过机器学习和神经引擎完成。苹果在设计A系列芯片时,专注于性能和效率。PhilSchiller表示:“我们公开谈论性能。但实际情况是,我们将其视为每瓦功耗可以提供的性能。”

  展望未来,苹果芯片制造团队将研究如何在iOS设备上使用应用程序,以优化未来芯片设计。PhilSchiller表示,对于不需要额外性能的应用程序,我们让它以去年A12芯片提供的性能运行,这样功耗更低。据PhilSchiller介绍,机器学习在A13芯片中也扮演着重要角色,有助于管理电池寿命和优化性能。
