The development of caches and caching is one of the most significant events in the history of computing. Virtually every modern CPU core from ultra-low power chips like the ARM Cortex-A5 to the ...

A CPU relies on various kinds of storage to optimally run programs and power a computer. These include components like hard disks and SSDs for long-term storage, RAM and GPU memory for fast, temporary ...

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 ...

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 ...

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 ...

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 ...

Since the earliest days of microprocessors, system designers have been plagued by a problem in which the speed of the CPU's operation exceeded the bandwidth of the memory subsystem to which it was ...

In a computer, the entire memory can be separated into different levels based on access time and capacity. Figure 1 shows different levels in the memory hierarchy. Smaller and faster memories are kept ...
