The NVIDIA A800 is the China-export-compliant version of the A100 SXM, with NVLink interconnect bandwidth reduced from 600 GB/s to 400 GB/s to comply with U.S. export regulations that were in effect at launch. Core compute performance — 312 TFLOPS FP16 and 80 GB HBM2e at 1,935 GB/s — is essentially identical to the A100 80GB, making it fully capable for LLM training and inference. It was widely deployed in Chinese AI clusters, powering training runs for several frontier Chinese LLMs, before being subsequently banned under tightened October 2023 export controls.
Beyond LLMs

Architecture
Ampere is NVIDIA's second-generation RTX architecture, built on Samsung's 8nm process. It introduced 3rd-generation Tensor Cores with support for sparsity-accelerated INT8 operations and improved FP16 throughput over Turing.
AI Relevance
Sparsity-aware Tensor Cores can effectively double throughput for structured sparse workloads. However, the lack of FP8 support means quantized inference is less efficient than Ada Lovelace or Blackwell.
