What’s the difference between A800 and A100?

Q: What’s the difference between A800 and A100?

A800 is the China-market variant of the A100: identical compute and memory specs per GPU (80 GB HBM2e); the main difference lies in inter-GPU interconnect bandwidth — public data shows NVLink reduced from ~600 GB/s to ~400 GB/s. Pricing (as of 2026-11-12): A100 80GB at ¥5.47/hour minimum, A800 80GB at ¥5.15/hour minimum. For single-GPU workloads, user experience is nearly identical — choose based on price. For multi-GPU training, prioritize A100 or newer H-series GPUs.

Is It Still Worth Renting A-Series GPUs?

A100/A800 are flagship GPUs from the 2020s; on-demand rental rates have dropped to less than half their original launch prices. They remain fully capable for fine-tuning and inference of 7B–30B models — representing the ‘mature & affordable’ tier. For higher throughput, upgrade to H100/H200. Daily price series for both generations are available at /market.
