When to Choose the H100 PCIe
Select the H100 PCIe for large-scale AI training and inference: its 80 GB VRAM handles models exceeding 32 GB, such as 70B-parameter LLMs, without multi-GPU sharding. The 1979 TFLOPS FP16 and 3958 TFLOPS FP8 deliver rapid convergence and high-throughput serving, ideal for production environments.
Enterprises with NVLink or PCIe 5.0 infrastructure benefit from H100's interconnects, enabling efficient multi-node scaling at $1.25 per hour starting price.
When to Choose the Tesla V100 32GB
Opt for the V100 32GB in budget-constrained or legacy setups: at $0.29 per hour average $1.01, it undercuts H100 costs by over 60 percent while delivering 125 TFLOPS FP16 for prototyping.
It suits PCIe 3.0 clusters running established Volta-optimized code, where 32 GB VRAM and 300W TDP fit dense, low-power deployments without refactoring.
Use Cases
H100's 1979 TFLOPS FP16 outperforms V100's 125 TFLOPS by over 15x, slashing training times for billion-parameter models. Its 80 GB VRAM supports massive batches without splitting.
H100's 3958 TFLOPS FP8 enables low-latency serving of large models, far beyond V100's capabilities. The 3350 GB/s bandwidth handles high request volumes efficiently.
With 67 TFLOPS FP32 and 80 GB VRAM, H100 accelerates fine-tuning on datasets too large for V100's 15.7 TFLOPS and 32 GB. It reduces iterations significantly.
H100's superior FP16 and memory bandwidth generate images 10x faster than V100, supporting high-resolution diffusion models. Larger VRAM fits complex pipelines.
V100's 15.7 TFLOPS FP32 suffices for many simulations at low $0.29 per hour cost. H100's 67 TFLOPS excels in memory-intensive HPC but at higher power and price.
