Best for Performance
NVIDIA H100 SXM
Best for Value
NVIDIA A100 80 GB SXM
Choose NVIDIA H100 SXM if...
You are training large language models (70B+ parameters), need FP8 Transformer Engine support, or require NVLink 4.0 for multi-GPU scaling. The H100 delivers up to 3x faster LLM training throughput compared to the A100.
Choose NVIDIA A100 80 GB SXM if...
You need a proven, cost-effective GPU for inference workloads, fine-tuning mid-size models (7B-30B), or running mixed AI/HPC workloads. The A100 offers excellent performance per rupee and has a mature software ecosystem.

Frequently Asked Questions
Is the NVIDIA H100 worth the price premium over the A100 in India?
For large-scale LLM training, yes. The H100 delivers roughly 3x the training throughput for models like GPT and LLaMA, and its FP8 Transformer Engine dramatically accelerates transformer-based workloads. However, for inference-only deployments or smaller model fine-tuning, the A100 remains an excellent choice at a significantly lower price point.
Can I use A100 GPUs for LLM training?
Yes. The A100 80 GB can train models up to approximately 30B parameters on a single GPU and larger models across multiple GPUs using tensor parallelism. It remains widely used for training in production environments, though the H100 is substantially faster for this workload.
What is the power consumption difference between H100 and A100?
The H100 SXM draws 700W TDP compared to the A100 SXM's 400W. This means H100-based deployments require stronger power delivery and cooling infrastructure, which is an important consideration for Indian data centres where power costs and cooling challenges are significant.
Are H100 GPUs available for purchase in India?
Yes, NVIDIA H100 GPUs are available through authorized distributors and system integrators in India, including RawCompute. Lead times can vary depending on demand. Both SXM and PCIe variants are available.
