RTX 4090 vs H200
Explore a head to head comparison of specifications, performance, and pricing.
RTX 4090
The NVIDIA RTX 4090 delivers high-performance computing capabilities for AI, machine learning, and data science applications.
H200
The NVIDIA H200 is an advanced Hopper-based GPU that significantly boosts performance for generative AI, LLM, and HPC workloads with enhanced memory and bandwidth.
RTX 4090 vs H200: Which Should You Choose?
The H200 offers 141 GB of VRAM — 6× the 24 GB on the RTX 4090 — making it better suited for large model workloads that require holding more parameters in GPU memory. On FP16 throughput, the H200 delivers 267.6 TFLOPS versus 82.58 TFLOPS on the RTX 4090 — 3× faster for mixed-precision training and inference. Memory bandwidth favors the H200 at 0.00 TB/s compared to 0.00 TB/s on the RTX 4090, which directly impacts inference latency for memory-bandwidth-bound models. Architecturally, the RTX 4090 is built on Ada Lovelace while the H200 uses Hopper, reflecting different generational capabilities and optimizations. On Shadeform, the RTX 4090 starts from $0.60/hr versus $2.45/hr for the H200 — 308% more expensive — reflecting the performance premium. The H200 is available across 7 cloud providers on Shadeform compared to 3 for the RTX 4090, giving more options for region and pricing flexibility.
RTX 4090 — Best Use Cases

Frequently Asked Questions: RTX 4090 vs H200
The main differences are VRAM (24 GB vs 141 GB), FP16 throughput (82.58 vs 267.6 TFLOPS), architecture (Ada Lovelace vs Hopper). The RTX 4090 uses the Ada Lovelace architecture while the H200 is based on Hopper, giving each GPU different generational capabilities.
The H200 is generally better for large language model training due to its higher throughput and 141 GB of VRAM, which allows fitting larger models or larger batch sizes in a single pass. For smaller models or fine-tuning tasks where cost matters more, both GPUs can be effective.
On Shadeform, the RTX 4090 is available from $0.60/hr. The H200 starts from $2.45/hr. Prices vary by provider, region, and contract length. Reserved commitments can reduce hourly costs significantly compared to on-demand pricing.
The H200 has more VRAM at 141 GB, compared to 24 GB on the RTX 4090. Higher VRAM allows you to run larger models without quantization, use longer context windows, and process larger batch sizes — all of which improve throughput and reduce latency for memory-bound workloads.
Based on TFLOPS per dollar, the RTX 4090 offers better raw compute value at current Shadeform on-demand rates. However, the best choice depends on your specific workload — if you need the extra VRAM or throughput of the H200, paying the premium may be justified by faster job completion and lower total cost.
The H200 is currently available across 7 cloud providers on Shadeform's network, compared to 3 for the RTX 4090. Shadeform lets you deploy either GPU across all available providers from a single platform, so you can always find available capacity without manually checking each cloud.
Mixing different GPU types in a single training cluster is generally not recommended, as it creates performance bottlenecks where faster GPUs wait for slower ones. For best results, use a homogeneous cluster of either RTX 4090 or H200. Shadeform supports on-demand clusters of up to 64 GPUs of the same type with no commitment required.
