Benchmarking the Evolution of Performance and Energy Efficiency Across Recent Generations of Intel Xeon Processors
Balázs Drávai, István Z. Reguly · 2024
In the span of 1.5 years, Intel has launched four families of Xeon Processors, with some novel architectural features; first the Sapphire Rapids generation which featured a version with on-package HBM, the Emerald Rapids generation, and then differentiated by releasing the performance-oriented Granite Rapids and the efficiency-oriented Sierra Forest families. In this work, we evaluate the performance and efficiency of CPUs from each of these generations and variants, with a particular focus on bandwidth-bound high performance computing (HPC) applications. We contrast runtime and energy consumption figures and track trends across generations.
