Best Fit Applications

AI Training and Inference

The 80GB GPU memory capacity and Tensor Core acceleration support demanding AI training and inference workloads. NVIDIA vGPU documentation identifies framebuffer sizes above 40GB for training-oriented workloads.

High-Performance Computing

A800-80G is designed for high-performance computing, scientific workloads, and data-intensive analytics that require high-throughput GPU acceleration.

Data Center GPU Sharing

MIG technology can partition the GPU into up to seven isolated GPU instances, helping data centers assign GPU resources across multiple workloads when supported by the deployment environment.

Why A800-80G

80GB GPU Memory for Large Workloads

The 80GB HBM2 memory capacity provides the memory space required by large AI models, high-performance analytics, and other data-intensive workloads.

MIG-Based GPU Partitioning

MIG technology enables the GPU to be divided into up to seven isolated GPU instances, improving resource allocation for supported multi-tenant data center workloads.

NVLink Multi-GPU Scaling

NVLink provides up to 400GB/s of interconnect bandwidth for supported multi-GPU configurations, subject to the server platform and compatible bridge configuration.
