AmpereComputing/panthera
Ampere's CPU Performance Model
Panthera is Ampere's cycle-accurate CPU performance simulator, built over 8 years by its architecture team to evaluate microarchitectural tradeoffs for its cloud processors. Now open-sourced as a reference implementation, it lets users model AmpereOne-class cores and correlate results against real Ampere silicon available in public clouds.
Why now: Ampere just open-sourced an industrial-grade, silicon-calibrated performance model—historically a closely guarded trade secret—sparking attention as a rare, human-authored (pre-generative-AI) resource for architecture research.
Who it is for: Computer architecture researchers, graduate educators, and performance engineers who want a realistic server-CPU baseline to study and validate microarchitectural ideas.
