Performance Analysis
The L40S outperforms the RTX 4070 SUPER significantly in raw compute: its 362 TFLOPS FP16 capability dwarfs the 35.5 TFLOPS of the RTX 4070 SUPER, enabling faster model training and inference in machine learning pipelines. The FP16 to FP32 ratio on the L40S, at 362 TFLOPS to 91 TFLOPS, reflects optimized tensor cores for half-precision workloads common in deep learning, whereas the RTX 4070 SUPER maintains parity at 35.5 TFLOPS for both, limiting its efficiency in specialized AI tasks.
Memory specifications further favor the L40S: 48 GB VRAM supports larger batch sizes and complex models without swapping, compared to 12 GB on the RTX 4070 SUPER. The L40S's 864 GB/s bandwidth, 71 percent higher than the 504 GB/s of the RTX 4070 SUPER, reduces bottlenecks during data-intensive operations like LLM fine-tuning. Power draw differs too, with the L40S at 350W TDP versus 220W for the RTX 4070 SUPER, impacting density in cloud deployments.
In real-world terms, these specs mean the L40S handles enterprise-scale AI with higher throughput, while the RTX 4070 SUPER suits smaller-scale or cost-conscious inference where availability permits.

When to Choose the L40S
Choose the L40S for demanding AI workloads requiring substantial VRAM, such as training large language models that exceed 12 GB. Its 48 GB GDDR6X and 864 GB/s bandwidth enable processing of massive datasets with large batch sizes, and 362 TFLOPS FP16 accelerates inference at scale. Datacenter features like PCIe 4.0 interconnect support multi-GPU setups unavailable in consumer cards.
Cloud renters benefit from 22 live offers starting at $0.32 per hour, making it viable for production environments where the RTX 4070 SUPER lacks availability.
When to Choose the RTX 4070 SUPER
Opt for the RTX 4070 SUPER in scenarios with modest memory needs, like fine-tuning small models or running Stable Diffusion at 12 GB VRAM capacity. Its lower 220W TDP reduces power costs in single-user cloud instances, and 35.5 TFLOPS FP32 suffices for graphics-heavy tasks or entry-level compute.
It appeals where consumer-grade availability emerges, offering a balance for hobbyists or developers avoiding datacenter pricing premiums.
Use Cases
The L40S's 48 GB VRAM and 362 TFLOPS FP16 handle large models and datasets that exceed the RTX 4070 SUPER's 12 GB limit. Higher bandwidth of 864 GB/s supports efficient training batches.
L40S delivers 362 TFLOPS FP16 for high-throughput serving, with 48 GB VRAM accommodating multiple concurrent requests. RTX 4070 SUPER's 35.5 TFLOPS limits scale.
