Cache Memory: Definition & Concept from Chapter 2/ Lesson 12 18K In computer memory systems, cache memory is a small memory storage that can be accessed easily. Learn about cache memory, the different types of cache memory such as the CPU cache and multi-level caches, and understand how the...
Cache memory is a chip-based computer memory that helps you efficiently retrieve data from the Computer’s memory. Usually, it serves as a temporary storage where a computer’s processor helps retrieve data between RAM and CPU. Cache memory is a critical part of modern computing. ...
The more Processor Cache you have (512 is better than 256), the more data you could have in the cache for faster processing. Modern CPU no longer uses external cache. Both L1 and L2 are parts of the CPU now. Modern desktop PC and server CPUs have three independent caches: an instructio...
Like L1 cache, L2 cache is often exclusive to a single CPU core, but in some CPUs, it’s shared between multiple cores. It’s also much, much larger; for example, each P-core in the Core i9-12900K has 80 kilobytes of L1 cache, as well as 1.25 megabytes of L2 cache, nearly 16...

CPU cache architecture Modern CPUs generally use three layers of CPU cache labelled L1-3, with lower-numbered caches being closer to the CPU cores, faster, and more expensive. Each individual CPU core in a multi-core CPU has its own L1 cache. It is typically split into two portions, the...
Hard drive cache, or disk buffer, is a lesser known hardware spec that can have a big impact on how efficient your data storage is. Learn how it works.
does not exist in the cache memory, it should be read from RAM, hence, it takes more cpu clock to read the specified address and this time is calculated by the multiplication of the miss rate and the penalty of this miss in time of reading data from RAM which is denoted by miss ...
Cache: A tiny amount of high-speed memory Source: AMD Cache is actually a pretty recent development in processors, dating back to the 1990s, and it was invented because of RAM. RAM is a key component in computers that stores a significant amount of data that processors (like CPUs and GPUs...
Cache lines are often 64 bytes, other sizes also exist. My very simple question is: is there any theory behind this number, or is it just the result of the vast amount of tests and measurements that engineers behind it undoubtedly do? Either way, I was wondering what those (the theory...
