CPU cache is the fast memory between the cores and main memory. What L1, L2, and L3 each do, why cache lines are 64 bytes, and when more cache actually makes a processor faster.

Let the era of 3D V-Cache in HPC begin. Inspired by the idea of AMD’s “Milan-X” Epyc 7003 processors with their 3D V-Cache stacked L3 cache memory and then propelled by actual benchmark tests pitting ...

I'm studying for the A+ exam, so the questions are coming in droves for now. Now that L2 cache has been integrated into the processor and runs at full speed, what differentiates it from L1 cache? I'm ...

I'm planning on upgrading my cpu/mobo to an a64 combo, but I want to know what some of the advantages are in having 1mb of L2 cache over 512k. Is it worth the extra money? From what I've read, it ...

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 ...

Intel’s upcoming Nova Lake processor introduces a different approach to its cache architecture by having two performance cores share a 4MB L2 cache. This change is a departure from the current Arrow ...

AMD’s 7800X3D and 7950X3D hold the top spot in CPUs for gaming, not because they have the most cores or the highest clock speeds, but because they have the most cache. But what is CPU cache, anyway?

Even after all of our refinements to the technologies; even despite innumerable advancements, the single biggest bottleneck for superior CPU performance is still simply getting data into and out of ...
