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 ...

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 ...

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 ...

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 ...

Confusion arose due to a discrepancy in the reported L2 cache size. Initial materials listed it as 36 MB, conflicting with earlier 2023 leaks that indicated a 48 MB cache, a 33% increase from the RTX ...

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 ...

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 ...

In the eighties, computer processors became faster and faster, while memory access times stagnated and hindered additional performance increases. Something had to be done to speed up memory access and ...

"CPUcacheIs multilayered in the way that L1 is 32 KB, L2 is 256 KB, L 3 is 2 MB, why is it not possible with L1 cache of 32 KB + 256 KB + 2 MB? "Fabian Giessen (ryg) responds clearly to the simple ...
