The NVIDIA H800 is a China-export-compliant variant of the H100, retaining the full Hopper compute capability — 80 GB HBM3 and Transformer Engine with FP8 — but with NVLink bandwidth cut to approximately 400 GB/s (down from H100's 900 GB/s) and FP64 performance capped at 1 TFLOPS. For single-GPU LLM inference, H800 performance is essentially identical to H100 SXM, making it highly effective for serving 70B models at FP16. The reduced NVLink bandwidth imposes a penalty for multi-GPU tensor parallelism in large training runs, which is why it was designed to be compliant. Like the A800, it was later banned under October 2023 export controls.

Architecture
Hopper is NVIDIA's datacenter-focused architecture succeeding Ampere. Built on TSMC 4N, it introduces the Transformer Engine with automatic FP8/FP16 mixed-precision training, HBM3/HBM3e memory, and NVLink 4.0 for multi-GPU scaling. The H100 flagship delivers up to 3x the AI training performance of A100.
AI Relevance
The Transformer Engine automatically manages FP8 precision for optimal training speed without accuracy loss. With up to 141 GB HBM3e (H200), Hopper GPUs can hold the largest open-weight models entirely in GPU memory, making them the workhorse of AI datacenters.

NVIDIA H800 80GB has 80 GB of VRAM available for AI model inference. This determines which models and quantization levels you can run locally.
Yes, NVIDIA H800 80GB is excellent for running LLMs locally with top compatibility scores above 80/100.
For coding on NVIDIA H800 80GB, we recommend Qwen3-Coder-Next. It achieves 164.1 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 H800 80GB: NVIDIA H800 80GB, Mac Studio M2 Ultra 128GB. Upgrading would unlock larger models and faster inference speeds.
Yes, NVIDIA H800 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 H800 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 H800 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 H800 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 H800 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 H800 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 H800 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 H800 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.
