Why a Faster CPU Won't Make Your Computer Faster: The Memory Hierarchy Explained
Understanding Computer Memory Architecture and SSD Internals
A deep dive into computer memory architecture, from the basics of memory structure and operations to the memory hierarchy, CPU caches, memory interleaving, and the evolution of memory modules from SIMM to DIMM and SO-DIMM. The article explains why faster processors don't proportionally improve performance due to memory latency, and how techniques like caching and interleaving mitigate this bottleneck.
If the processor executes instructions faster than the memory can supply them, the processor simply waits.
