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.

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.

NVIDIA A800 80GB has 80 GB of VRAM available for AI model inference. This determines which models and quantization levels you can run locally.
Yes, NVIDIA A800 80GB is excellent for running LLMs locally with top compatibility scores above 80/100.
For coding on NVIDIA A800 80GB, we recommend Qwen3-Coder-Next. It achieves 101.9 tokens per second with 244K context window. Qwen3-Coder-Next is a specialized fit for Coding. It is a recent-generation family, which helps on current local SOTA workloads. It fits natively with comfortable headroom. Context coverage stays within the requested workload envelope. Known distribution channels: huggingface, ollama, lm-studio.
There are 5 upgrade path(s) from NVIDIA A800 80GB: NVIDIA A800 80GB, Mac Studio M2 Ultra 128GB. Upgrading would unlock larger models and faster inference speeds.
Yes, NVIDIA A800 80GB with 80 GB of usable memory can run Flux.1 Dev at FP16 natively. Flux is a 12B parameter diffusion transformer that produces high-quality images. You can also run the Schnell variant for faster generation.
NVIDIA A800 80GB (80 GB VRAM) can handle various AI generation tasks beyond LLMs. For image generation, SDXL and Stable Diffusion 3.5 run well. Flux.1 Dev also runs natively for state-of-the-art image quality. For video, LTX Video 2.3 can generate short clips. Check the AI Capability Matrix above for detailed compatibility.
NVIDIA A800 80GB is excellent for AI image generation. With 80 GB of usable memory, it runs all major diffusion models including Flux.1, SDXL, and Stable Diffusion 3.5 at full precision. You can generate high-resolution images quickly and even handle video generation models.
Yes, NVIDIA A800 80GB with 80 GB of usable memory can run Qwen 3.5 27B at Q8 (near-lossless, ~28.9 GB) or even FP16 (~55.4 GB) depending on your context needs. This setup provides an excellent experience with this model. Use Ollama or vLLM for best results.
With 80 GB VRAM on NVIDIA A800 80GB, use Q8_0 for most models — it is near-lossless and you have the memory for it. For 70B+ models, Q6_K offers excellent quality. Reserve Q4_K_M for 100B+ models or when you need maximum context length.
NVIDIA A800 80GB already has strong memory bandwidth, so the next limit is often memory capacity and context headroom rather than raw decode speed. For local LLMs, fit first and bandwidth second is the right mental model.
NVIDIA A800 80GB supports up to 8× GPU scaling via NVLink at 400 GB/s. With 8× GPUs, you get 640 GB effective memory with a 0.88× scaling factor per GPU. This enables running models like Qwen 3.5 397B A17B and Kimi K2.5 that don't fit on a single card.
NVLink is recommended for NVIDIA A800 80GB multi-GPU inference, providing 400 GB/s interconnect bandwidth with only 12% scaling overhead. PCIe-only setups work but have higher overhead (~25%) due to limited inter-GPU bandwidth.
