Performance Evaluation of Intel and AMD Memory Hierarchies Using a Simulation-driven Approach With Gem5

Abstract

Along with the necessity of more computational power, CPUs are evolving quickly. Companies are developing new generations of CPUs every 1–2 years, and many options compete for market share. Hence, researchers and companies must develop a method to compare and select the best processor that fits their needs. This paper presents a simulation-driven alternative for CPU Memory Hierarchy evaluation and comparison. Furthermore, this work compares two rival processors engineered by Intel and AMD. The investigation culminates in the observation that AMD’s processor performs better with fewer cores for several cases, while Intel’s equivalent exhibits enhanced results when all available cores are used.
