This paper updates the survey of AI accelerators and processors from past
three years. This paper collects and summarizes the current commercial
accelerators that have been publicly announced with peak performance and power
consumption numbers. The performance and power values are plotted on a scatter
graph, and a number of dimensions and observations from the trends on this plot
are again discussed and analyzed. Two new trends plots based on accelerator
release dates are included in this year's paper, along with the additional
trends of some neuromorphic, photonic, and memristor-based inference
accelerators.Comment: 10 pages, 4 figures, 2022 IEEE High Performance Extreme Computing
