How to Choose Between A100, H100, or V100 GPUs in GaaS?

Cyfuture Cloud's GPU as a Service (GaaS) offers NVIDIA A100, H100, and V100 GPUs for AI, ML, and HPC workloads, with selection depending on performance needs, budget, and scalability.​

- Choose V100 for budget-friendly, legacy, or lighter AI tasks with lower costs.​

- Choose A100 for balanced performance in multi-user cloud setups, training medium models efficiently.​

- Choose H100 for cutting-edge, large-scale AI training/inference needing maximum speed and memory.​

GPU Specifications Comparison

NVIDIA V100 (Volta architecture) features 5,120 CUDA cores, 640 Tensor Cores, 16-32GB HBM2 memory at 900 GB/s bandwidth, and up to 125 TFLOPS FP16 Tensor performance. The A100 (Ampere) advances with 6,912 CUDA cores, 432 3rd-gen Tensor Cores, 40GB HBM2e at 1.6 TB/s, and 312 TFLOPS FP16. H100 (Hopper) leads via 4th-gen Tensor Cores, 80GB HBM3 at 3.35 TB/s (up to 94GB/3.9 TB/s variants), and peaks at 1,979 TFLOPS FP16 or 3,958 TFLOPS FP8.​

H100 delivers 2-6x A100 speed in AI tasks due to FP8 support and Transformer Engine.​

Performance for Key Workloads

V100 suits scientific computing and smaller deep learning models but lags in modern large language models (LLMs). A100 excels in cloud AI training/inference with MIG partitioning for multi-tenancy, offering 10x V100 FP32 gains. H100 shines for massive datasets, providing 2.4x A100 training throughput and 1.5-2x inference speed, ideal for real-time services.​

In Cyfuture GaaS, H100 handles enterprise-scale models fastest, while V100 fits startups testing prototypes.​

Cost and Power in Cyfuture GaaS

Cyfuture offers pay-as-you-go pricing: H100 ~$2.80-$3.50/GPU/hour (reserved ~$1.85), A100 lower at ~$1-1.5/GPU/hour equivalent, V100 most affordable for entry-level. H100's higher hourly rate offsets via faster completion—e.g., 4x A100 cluster trains in 4 hours vs. 10, costing less overall ($40 vs. $50). Power: H100 at 700W vs. A100 400W, but 30% efficiency gains reduce bills; Cyfuture handles infrastructure.​

No upfront costs in GaaS make scaling seamless for Delhi users with low-latency APAC data centers.​

Cyfuture Cloud GaaS Advantages

Cyfuture provides A100/H100/V100 clusters with pre-installed frameworks, 100 Gbps networking, NVMe storage, and 24/7 support. Flexible models suit startups to enterprises, 20-40% cheaper than AWS/GCP. Instant provisioning accelerates AI without DevOps.​

Conclusion
Select V100 for cost-sensitive pilots, A100 for versatile production, or H100 for peak performance in Cyfuture GaaS—test via pay-as-you-go to match workloads precisely, ensuring optimal ROI.​
