无论你写什么样的代码都会交给 CPU 来执行，所以，如果你想写出性能比较高的代码，这篇文章中提到的技术还是值得认真学习的。另外，千万别觉得这些东西没用，这些东西非常有用，十多年前就是这些知识在性能调优上帮了我的很多大忙，从而跟很多人拉开 ...

有了内存，为什么还需要 CPU Cache？ CPU 是怎么读写数据的？ 如何让 CPU 能读取数据更快一些？ CPU 伪共享是如何发生的？又该如何避免？ CPU 是如何调度任务的？如果你的任务对响应要求很高，你希望它总是能被先调度，这该怎么办？ 这篇，我们就来回答这些问题。

Intel released a new CPU model this week, the Intel Core i9 7900X, which is the latest model to feature a new cache architecture that hardware experts believe it will make exploitation of side-channel ...

In the early days of computing, everything ran quite a bit slower than what we see today. This was not only because the computers' central processing units – CPUs – were slow, but also because ...

CPUs have a number of caching levels. We've discussed cache structures generally, in our L1 & L2 explainer, but we haven't spent as much time discussing how an L3 works or how it's different compared ...

When talking about CPU specifications, in addition to clock speed and number of cores/threads, ' CPU cache memory ' is sometimes mentioned. Developer Gabriel G. Cunha explains what this CPU cache ...

To understand the design decisions behind the Ryzen 7 5800X3D, you must understand cache and how it works inside of a processor. Cache is an often underappreciated, yet vitally important, piece of any ...
