Gen X Performance Tuning

The text discusses the use of AMD 2nd Gen EPYC 7642 processors in tenth-generation "Gen X" servers and highlights tuning efforts that led to an additional 6% performance. It explains the concept of Thermal Design Power (TDP) and dynamic power, emphasizing that TDP is about how much heat a processor generates rather than its maximum or average power draw. The text also explores determinism modes and Configurable Thermal Design Power (cTDP), which can be adjusted to optimize performance and power consumption. Finally, it mentions the exploration of Nodes Per Socket (NPS) options in the AMD EPYC 7642 processor but does not observe significant deltas in terms of performance. The text concludes by stating that further improvements are possible through collaboration with AMD and internal teams within Cloudflare.
