历史
The export-compliant A100 built for China after the October 2022 controls.
您正在查看一条芯片记录：该处理器是什么、其关键规格、谁设计它、谁制造它、谁供应其零部件，以及它被用在哪里。
When US export rules capped chip-to-chip interconnect speeds for China, NVIDIA cut the A100's NVLink from 600 to 400 GB/s and shipped it as the A800. It was itself banned by the tightened October 2023 rules, making it a marker of how policy now shapes chip design.
