Performance Analysis
Dense FP16 performance reaches 362.05 TFLOPS on the L40S compared with 57 TFLOPS dense FP16 on the Quadro RTX 4000 which produces a ratio of 362.05 to 57. The FP32 figure of 91.6 TFLOPS on the L40S versus 7.1 TFLOPS on the Quadro RTX 4000 indicates greater headroom for mixed precision workloads during training and inference. Memory bandwidth of 864 GB/s versus 416 GB/s allows larger batch sizes on the L40S before memory capacity of 48 GB becomes limiting relative to 8 GB. Sparse FP16 performance of 733 TFLOPS on the L40S has no direct counterpart on the Quadro RTX 4000 so only dense to dense comparisons apply.

When to Choose the L40S
The L40S suits workloads that require 48 GB VRAM and dense FP16 throughput of 362.05 TFLOPS such as large model training or inference where the 864 GB/s bandwidth supports sustained data movement. Its 350 W TDP and PCIe 4.0 interconnect fit environments that prioritize raw compute capacity over power draw.
When to Choose the Quadro RTX 4000
The Quadro RTX 4000 fits scenarios limited to 125 W TDP and 8 GB VRAM where the 57 TFLOPS dense FP16 and 7.1 TFLOPS FP32 suffice for lighter inference or legacy applications that do not exceed PCIe 3.0 bandwidth.
Use Cases
The L40S supplies 48 GB VRAM and 362.05 TFLOPS dense FP16 which exceed the Quadro RTX 4000 limits for model scale.
Dense FP16 at 362.05 TFLOPS and 864 GB/s bandwidth on the L40S enable larger batch processing than the 57 TFLOPS and 416 GB/s on the Quadro RTX 4000.
The L40S 91.6 TFLOPS FP32 and 48 GB memory support fine-tuning steps that the Quadro RTX 4000 7.1 TFLOPS FP32 and 8 GB memory cannot accommodate at equivalent scale.
Memory capacity of 48 GB and dense FP16 of 362.05 TFLOPS on the L40S allow higher resolution generation compared with 8 GB and 57 TFLOPS on the Quadro RTX 4000.
FP32 performance of 91.6 TFLOPS on the L40S surpasses 7.1 TFLOPS on the Quadro RTX 4000 for compute intensive simulations.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the L40S and the Quadro RTX 4000. Dense and sparse throughput are listed separately.
- Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
- The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
