Frequently Asked Questions (FAQ)

What’s the difference between A100 80GB and A100 40GB?

Answer: The A100 80GB features double the memory (80GB vs 40GB), higher memory bandwidth (2TB/s vs 1.55TB/s SXM), and double the MIG instance size (10GB vs 5GB per instance). This translates to up to 3X faster training for large models, 2X faster data analytics, and ability to handle models with up to 70B+ parameters versus approximately 35B for the 40GB variant.

What is Multi-Instance GPU (MIG) and why is it important?

Answer: MIG allows a single A100 to be partitioned into up to 7 independent GPU instances, each with dedicated memory (10GB in 80GB model), cache, and compute resources. This enables 7X higher utilization for inference workloads, secure multi-tenancy with hardware isolation, Quality of Service (QoS) guarantees, and flexible resource allocation for varying workload sizes. It’s perfect for cloud providers and enterprise data centers.

PCIe vs SXM: Which form factor should I choose?

Answer:

• Choose PCIe if you need flexibility to use standard servers, easier upgrades and maintenance, 1-8 GPU configurations, lower power consumption (300W), and budget-friendly deployment.
• Choose SXM if you need maximum performance (400W TDP), highest memory bandwidth (2,039 GB/s), 8-16 GPU scalability with NVSwitch, dense data center deployments, and best performance-per-rack-unit.

Can the A100 80GB run all major AI frameworks?

Answer: Yes. The A100 is fully compatible with all major AI/ML frameworks including TensorFlow, PyTorch, MXNet, JAX, ONNX, Keras, PaddlePaddle, and over 2,000 GPU-accelerated applications available in the NVIDIA NGC catalog.

How many A100 GPUs can be connected together?

Answer:

• PCIe version: Up to 2 GPUs via NVLink Bridge, up to 8-10 per server
• SXM version: Up to 16 GPUs interconnected via NVSwitch at 600 GB/s per GPU
• Multi-node scaling: Unlimited with InfiniBand networking

What size AI models can the A100 80GB train?

Answer: The A100 80GB can train:

• Single GPU: Models up to approximately 70-75 billion parameters (depending on optimization)
• 8 GPUs: Models up to 500-600 billion parameters
• Multi-node: Trillion+ parameter models (like GPT-3, GPT-4)
• With memory-efficient techniques (gradient checkpointing, ZeRO optimization), even larger models are possible

Is the A100 suitable for gaming or consumer use?

Answer: No. The A100 is a data center compute GPU with no display outputs, designed for 24/7 enterprise workloads, AI training/inference, and HPC. It’s not optimized for gaming. For gaming and consumer workstations, consider GeForce RTX series GPUs.

What’s the typical lifespan and reliability of A100 GPUs?

Answer: A100 GPUs are engineered for 24/7 operation in data centers with Mean Time Between Failures (MTBF) typically 5-7 years, ECC memory that protects against data corruption, enterprise-grade components built for reliability, thermal design optimized for sustained workloads. Many data centers plan for 3-5 year refresh cycles.

How does A100 compare to newer H100/H200?

Answer:

• H100: 2-3X faster for some AI workloads, HBM3 memory, higher price
• H200: H100 with 141GB HBM3e, optimized for LLMs
• A100 advantages: More mature ecosystem, wider availability, better cost-performance for many workloads, still highly competitive for most applications
• Recommendation: A100 80GB remains excellent value for most AI/HPC workloads in 2025

What power and cooling requirements does the A100 need?

Answer:

• PCIe: 300W TDP, requires dedicated 8-pin PCIe power, standard air cooling in well-ventilated racks
• SXM: 400W TDP (500W CTS), requires active liquid cooling in HGX/DGX systems
• Data center cooling: Maintain ambient temperature 20-25°C for optimal performance
• Power delivery: Ensure clean, stable power with UPS backup

Can A100 be used for cryptocurrency mining?

Answer: While technically possible, it’s not recommended or cost-effective. The A100 is optimized for AI/HPC workloads, not mining algorithms. GeForce GPUs offer better mining performance-per-dollar. Using A100 for mining would be a significant waste of its advanced AI acceleration capabilities.

What warranty and support does the A100 come with?

Answer: NVIDIA A100 typically includes 3-year standard warranty (varies by reseller), NVIDIA Enterprise Support options available, regular driver updates and security patches, access to NGC containers and optimized software, and extended warranties available through NVIDIA partners.

Is the A100 still relevant in 2025?

Answer: Absolutely yes. Despite newer generations (H100/H200), the A100 remains core infrastructure for major AI companies, offers excellent performance for most AI workloads, better availability than newer generations, superior cost-performance ratio, proven reliability and mature software stack, and will remain relevant for several more years.
