NVIDIA’s NVLink and Fusion Drive Revolutionize AI Inference Performance

NVIDIA's NVLink and NVLink Fusion technologies are setting new benchmarks in AI inference performance, addressing the escalating demands of increasingly complex AI models. The fifth-generation NVLink, launched in 2024, supports 72 GPUs with an all-to-all communication bandwidth of 1,800 GB/s, marking an 800-fold improvement over its inaugural iteration. This leap underscores NVIDIA's commitment to scalable, high-performance computing solutions.

NVLink Fusion offers hyperscalers unprecedented customization and flexibility, enabling seamless integration of scale-up technologies. The evolution from NVLink's 2016 debut to its current iteration reflects a strategic response to the trillion-parameter models now dominating the AI landscape. Joe DeLaere's insights in a recent Nvidia blog post highlight the critical role of GPU clusters in managing these computational behemoths.
