上周，苹果发布了搭载最新M4芯片的三款Mac。 M4是苹果自己设计的芯片，ARM架构，采用台积电第二代3nm制程制造。 其实它早在24年5月就在iPad Pro上搭载了，只是最近才把它放在了Mac上。 这一代同上一代M3一样，是3nm制程。但M4的3nm是台积电的第二代3nm工艺，在能效表现上又跨了一大步，并且竟然没扯到蛋。 所以，这一代Mac的性能相比上一代提升了30%，MacBook Pro续航也大大增加，达到了24小时，让俺们牛马在实现724工作制的道路上又近了一步。 M4一共有三个版本，M4、M4 Pro以及M4 Max。 即所谓的中杯、大杯、超大杯。 满血版的普通M4有10个CPU核心，10个GPU核心和16个NPU核心。 其中，10个CPU核心包含4颗性能核心和6颗能效核心。 这颗芯片搭载在基础款的MacBook Pro、Mac mini和iMac上。 不过要注意，iMac最低配上的M4是残血版，它的CPU和GPU都只有8核。 估计未来的M4 MacBook Air低配款同样也是残血M4。 这是在geekbench上，满血版10核M4的跑分： 因为工艺进步，M4的单核跑分大幅领先M3的3100，史上最高。 从多核跑分上来看也是不得了，10核的M4达到了12核M2 Max的水平。 这里简单说下单核跑分和多核跑分的意义。 单核跑分反映其中的一个CPU核心的性能。单核分数越高，在处理单线程任务的时候，性能就越好，用起来越丝滑。 日常的很多工作大多属于是这种类型的，比如上上网、做做表什么的。 因此，普通款的M4对于轻度用户来说是个很好的选择。如果不搞编程、不剪视频啥的，我觉得还可以等等明年更便宜的MacBook Air。 而多核跑分反映的就是所有CPU集火输出的能力，对于专业用户来说，比如剪视频、编译代码啥的，多核跑分就很重要。 因此，单论CPU性能，M4用起来绝对比M2 Max爽。 二、大杯：M4 Pro 现在我们来看看中档的M4 Pro。 M4 Pro其实有两款，差价1500块： 12核CPU、16核GPU 14核CPU、20核GPU 满血版的是14核CPU和20核GPU。CPU核心多了4个，但GPU数量相比普通M4翻倍了。 M3 Pro的内存带宽很高，达到了273GB/s，相比M3 Pro提升了75%。 高带宽意味着短时间内可以向内存读写更多的内容，在处理重度任务时比较有优势，比如视频渲染、大模型训练等等。 另外，M4 Pro支持雷雳5接口，而普通M4只支持雷雳4。 「雷雳」就是英特尔的雷电技术，用的是USB Type-C接口。雷雳5传输速率可以达到120 Gbit/s，非常快，是雷雳4的三倍。 如果你有雷雳5设备，传输数据的时候就会非常爽。 但雷雳5的设备价格非常贵，就连一根数据线都可能要上百块，你的钱包可能会非常不爽。 我们来看看M4 Pro的跑分： 单核就不说了，所有M4都一样。
