Assembly Hall of Shame
Summary
Assembly Hall of Shame is a GitHub project by xoreaxeaxeax that ranks CPU instruction latency across x86 microarchitectures. It presents a leaderboard of instructions (e.g., fxrstor64, clflush, rdrand) and describes testing methodologies using MMIO, PCIe, and microcode behavior to stress CPUs. The page serves as a resource for performance engineers and enthusiasts exploring microarchitectural performance and open-source experimentation.
