—Particularly large-scale deep learning and artificial intelligence model training uses a lot of computational power and energy, so pose serious sustainability issues. The fast rise in model complexity has resulted in exponential increases in energy consumption, so increasing the demand for techniques maximizing computational efficiency and lowering environmental impact. This work explores environmentally driven performance optimization methods especially intended for advanced GPU architectures from NVIDIA, AMD, and other emerging GPU architectures. Our main focus is on investigating hardware-software co-design techniques meant to significantly increase memorylevel and kernel-level operations, so improving performance-perwatt measures. Our thorough research encompasses evaluations of specialized tensor and matrix cores, advanced memory optimization methods, and creative integration approaches that taken together result in notable energy efficiency increases. We also discuss important software-level optimizations that augment hardware capability, including mixed-precision arithmetic, advanced energy-aware scheduling algorithms and compilerdriven kernel enhancements. Moreover, we methodically point out important research gaps and suggest future directions necessary to create really sustainable artificial intelligence systems. This paper emphasizes how major increases in training efficiency can be obtained by co-design of hardware and software, so lowering the environmental impact of artificial intelligence without compromising performance. With this thorough analysis, we show that a comprehensive co-design approach can significantly increase training efficiency and lower the carbon footprint of AI without compromising performance.
