Simply put, the L1, L2, and L3 cache are extremely fast memory layers with L1 being the fastest followed by L2 and L3 cache. However, these unsung heroes have a lot more to their story than just ...

Now, CPU cache memory is not homogenous it exists in three (occasionally four) variants, namely L1, L2, and L3. The primary differences between these three variants will come down to speed ...

Let's explore why. The chips in the blue box are providing 64 KB of L2 cache for this 486 system. Back in the early days, computers worked entirely out of their main memory.

For example, Intel Core processors have fully inclusive L1+L3 cache. This means that the same data in Level 1, for example, can also be in Level 3.

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 ...

Cache memory consists of different levels called L1, L2, L3 and occasionally L4, which differ in location, speed and size. The cache memory is extremely fast and positioned as close as possible to ...

Recently, IBM debuted its Telum microprocessor with an interesting and unusual cache structure. Telum has the usual L1 and L2, but instead of a physical L3, the CPU deploys a virtual L3.

While L3 Cache is slower compared to L1 and L2 Caches, it is faster than RAM and offers significant boost to the performance of L1, L2 Cache. We can check the Processor Cache size in Windows 11/10 ...
