In terms of performance ARM claims it will exceed the A72 in all important metrics relevant to mobile workloads. Examples were scarce but on workloads such as BBench (Website loading benchmark) the A73 is claimed to be up to 10% better performance than the A72 – on the same process and frequency. SIMD/NEON (FFMEG Codec) workloads are supposed to improve by up to 5%, mostly a side-effect from the better memory subsystem. Memory sees the largest gains with up to 15% improvement (JMC Stream Copy 64b).

I asked what we should be expecting in terms of performance degradations and of course the biggest disadvantage will be in micro-benchmarks such as Dhrystone. ARM promises SPEC performance will be the same as on the A72 it’s likely that the downgrade from a 3-wide decoder to a 2-wide one won’t affect many relevant workloads. I saw the same behaviour reflected the A17 versus the A15 as the former was more than able to keep up with the larger microarchitecture in almost all of the workloads and benchmarks I threw at it, so I have little doubt that the A73 will be able show similar behaviour against the A72.

ARM这么玩从A72三发射退化到A73双发射，对于手机用户可能是好事，持续效能会有提升。但是对于复杂应用下的实际效能基本肯定要歇菜，看看ATOM和CORE M就知道了。

尼玛APPLE、高通和三棒都是努力提升CPU的IPC，轮到ARM倒是越活越回去了，真他妈的傻逼！

其实A72相比A57的改进也是简化，效果目前看起来挺好。

A72到A73是直接砍一条腿。。。。

发射端砍了性能不怎么下降就说明这发射端是多余干吃电的呀。
你不能拿core和atom比，两者执行端规模也有很大差异的。

最终用户才不管你几发射，能做到最高频率持续跑才说明钱没白花。

intel之于AMD不就是在发射多执行上更优秀么？
ARM上也同理？

水果A9是六发射，高通kyro是5发射，A72是3发射

单线程同频性能基本是A9>kyro>A72

开始从看频率变成看发射数了啊。参数党你好，参数党再见。

发射数是啥？听上去好厉害的样子。

有关系但没决定关系
A17双发射，A15三发射
同频A17略强，而且28nm工艺下的可实现频率A17也高一截。

A73据说是A17团队的作品，看样子是A17的64位升级版

a17比a15强啊。一直以为a17是a12半斤八两的

A17就是A12换新总线，结果就比A15猛了。

效能提升就行了，管他几发射，等芯片出来看测评。

看贴吧基佬的各种压力测试，在手机上跑，不是轮子多就跑得快的
