A CPU relies on various kinds of storage to optimally run programs and power a computer. These include components like hard disks and SSDs for long-term storage, RAM and GPU memory for fast, temporary ...

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 ...

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 ...

Some 45nm K10 based chips will be branded as Athlons. They are still based on the same architecture as Deneb. The main difference between the Phenom and Athlon chips will be that Athlons will not have ...

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 ...

AMD's 7800X3D and 7950X3D CPUs reign supreme in the gaming realm, not solely due to their core count or clock speeds, but primarily owing to their abundant cache. CPU cache refers to a small yet ...

Following his detailed leak about AMD’s Zen 5 CPUs early last month, RedGamingTech has now issued some updates to his previously alleged information. While most of the stuff remains largely the same, ...

Matthew is a PC Hardware Writer at XDA, having previously written for Digital Trends, Tom's Hardware, and other publications since 2018. He's mainly interested in the three way fight between AMD, ...

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 gap between the performance of processors, broadly defined, and the performance of DRAM main memory, also broadly defined, has been an issue for at least three decades when the gap really started ...
