Summary
🤩
Rockstar🎓
Top SchoolNikhil Gupta is a CPU Performance Architect with over a decade of deep experience in x86 and ARM microarchitecture performance modeling, currently based in Sunnyvale and working at Apple. He has led instruction cache, branch prediction, and decoder modeling across multiple CPU generations at AMD, owning simulator infrastructure and a custom trace format used for cross-site correlation and pre- and post-silicon validation. Known for turning microarchitectural concepts into measurable IPC improvements, he bridges rigorous analytical modeling with hands-on verification and hardware debug. His work spans the full performance flow from conceptual modeling to RTL and silicon correlation, and he holds three patents that reflect practical innovations in CPU performance.
