H100 vs MI300X — which GPU should I choose?

H100 if you need the broadest software ecosystem (CUDA, TensorRT, vLLM). MI300X if you need maximum VRAM (192GB vs 80GB) for large model inference. MI300X offers better $/TFLOP but NVIDIA's software stack is more mature.

How much VRAM do I need for LLM inference?

A model needs ~2x its parameter count in GB for FP16 inference (70B model = ~140GB VRAM). With INT8 quantization ~70GB, INT4 ~35GB. A single H100 (80GB) runs 70B at INT8; MI300X (192GB) runs it at full FP16.

Should we buy GPUs or use cloud GPU instances?

If running GPUs 60%+ of the time, on-premise ownership wins on 3-year TCO. Below 40% utilization, cloud is more cost-effective. Many enterprises use hybrid: owned hardware for baseline, cloud for peak demand.

What is the cheapest way to rent an H100 GPU?

As of 2026, H100 cloud pricing ranges from $2.23/hr (Lambda, RunPod spot) to $4+/hr (AWS, Azure on-demand). Reserved instances and spot pricing offer 30-60% savings. CoreWeave and Lambda typically offer the lowest rates.

What GPU is best for LLM training in 2026?

NVIDIA H200 SXM (141GB HBM3e) for proven clusters, B200 for next-gen 4-5x speedup over H100, or AMD MI300X (192GB) for budget-conscious teams. For JAX workloads, Google TPU v5p pods offer unmatched scale.

Use Spot for Training

Save 60-70% on training runs with checkpointing. GCP Spot offers up to 70% discount on A100/H100 instances.

Best for: Fault-tolerant training with checkpoints

Reserved for Inference

1-year commitments save 35-40% for always-on inference endpoints. Azure and AWS offer the deepest reserved discounts.

Best for: Production inference workloads

Lambda/CoreWeave for Value

GPU cloud specialists offer 2-4x lower per-GPU pricing than hyperscalers, ideal for teams that don't need full cloud ecosystems.

Best for: Pure GPU compute without cloud services
