L40S vs GH200
Explore a head to head comparison of specifications, performance, and pricing.
L40S
The NVIDIA L40S delivers high-performance computing capabilities for AI, machine learning, and data science applications.
GH200
The NVIDIA GH200 is an advanced Hopper-based GPU that significantly boosts performance for generative AI, LLM, and HPC workloads with enhanced memory and bandwidth.
L40S vs GH200: Which Should You Choose?
The GH200 offers 96 GB of VRAM — 2× the 48 GB on the L40S — making it better suited for large model workloads that require holding more parameters in GPU memory. On FP16 throughput, the GH200 delivers 267.6 TFLOPS versus 91.61 TFLOPS on the L40S — 3× faster for mixed-precision training and inference. Memory bandwidth favors the L40S at 0.86 TB/s compared to 0.00 TB/s on the GH200, which directly impacts inference latency for memory-bandwidth-bound models. Architecturally, the L40S is built on Ada Lovelace while the GH200 uses Hopper, reflecting different generational capabilities and optimizations. On Shadeform, the L40S starts from $0.74/hr versus $2.29/hr for the GH200 — 209% more expensive — reflecting the performance premium. The L40S is available across 7 cloud providers on Shadeform compared to 2 for the GH200, giving more options for region and pricing flexibility.
L40S — Best Use Cases
- •LLM inference and model serving
- •Image generation and diffusion models
- •Smaller fine-tuning runs
- •Cost-efficient GPU compute
Choose L40S when:
- ✓48 GB VRAM is sufficient for your workload
- ✓Cost efficiency is your primary concern
- ✓Your workload does not require peak FP16 throughput
- ✓You need flexibility across multiple cloud providers or regions
GH200 — Best Use Cases
- •Training large language models (7B–405B parameters)
- •High-throughput LLM inference
- •Mixture-of-experts and transformer workloads
- •Distributed multi-GPU training runs
Choose GH200 when:
- ✓You need 96 GB+ VRAM for large models or long context windows
- ✓Maximum performance justifies the higher cost
- ✓You are training large models or running high-throughput inference
- ✓Your preferred provider already has availability

Frequently Asked Questions: L40S vs GH200
The main differences are VRAM (48 GB vs 96 GB), FP16 throughput (91.61 vs 267.6 TFLOPS), architecture (Ada Lovelace vs Hopper). The L40S uses the Ada Lovelace architecture while the GH200 is based on Hopper, giving each GPU different generational capabilities.
The GH200 is generally better for large language model training due to its higher throughput and 96 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 L40S is available from $0.74/hr. The GH200 starts from $2.29/hr. Prices vary by provider, region, and contract length. Reserved commitments can reduce hourly costs significantly compared to on-demand pricing.
The GH200 has more VRAM at 96 GB, compared to 48 GB on the L40S. 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 L40S 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 GH200, paying the premium may be justified by faster job completion and lower total cost.
The L40S is currently available across 7 cloud providers on Shadeform's network, compared to 2 for the GH200. 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 L40S or GH200. Shadeform supports on-demand clusters of up to 64 GPUs of the same type with no commitment required.
