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.

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 ...

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 ...

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 ...

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 ...

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 12th-generation Alder Lake CPUs aren't that far from its 13th-gen Raptor Lake chips. There are lots of changes, of course, but from an end-user perspective, the biggest difference is the ...

HsinChu, Taiwan, Nov. 30, 2020 (GLOBE NEWSWIRE) -- Andes Technology Corporation, the leader in RISC-V CPU solutions, today proudly announces new members of AndesCore™: high performance superscalar ...

A number of discussion areas are harboring complaints of failing level 2 caches on Apple’s Lombard PowerBooks. As noted by Marc P., for some, the PowerBook woks fine without the L2 cache, albeit ...
