Explore a head to head comparison of specifications, performance, and pricing.
A6000
The NVIDIA A6000 delivers high-performance computing capabilities for AI, machine learning, and data science applications.
L40S
The NVIDIA L40S delivers high-performance computing capabilities for AI, machine learning, and data science applications.
A6000 vs L40S: Which Should You Choose?
Both the A6000 and L40S offer 48 GB of VRAM, putting them on equal footing for memory-bound workloads. On FP16 throughput, the L40S delivers 91.61 TFLOPS versus 38.71 TFLOPS on the A6000 — 2× faster for mixed-precision training and inference. Memory bandwidth favors the L40S at 0.86 TB/s compared to 0.77 TB/s on the A6000, which directly impacts inference latency for memory-bandwidth-bound models. Architecturally, the A6000 is built on Ampere while the L40S uses Ada Lovelace, reflecting different generational capabilities and optimizations. On Shadeform, the A6000 starts from $0.49/hr versus $0.74/hr for the L40S — 51% more expensive — reflecting the performance premium. The L40S is available across 7 cloud providers on Shadeform compared to 6 for the A6000, giving more options for region and pricing flexibility.

Frequently Asked Questions: A6000 vs L40S
The main differences are FP16 throughput (38.71 vs 91.61 TFLOPS), architecture (Ampere vs Ada Lovelace). The A6000 uses the Ampere architecture while the L40S is based on Ada Lovelace, giving each GPU different generational capabilities.
The L40S is generally better for large language model training due to its higher throughput and 48 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 A6000 is available from $0.49/hr. The L40S starts from $0.74/hr. Prices vary by provider, region, and contract length. Reserved commitments can reduce hourly costs significantly compared to on-demand pricing.
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 A6000, 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 6 for the A6000. 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 A6000 or L40S. Shadeform supports on-demand clusters of up to 64 GPUs of the same type with no commitment required.
