Performance Analysis
The L40 provides an FP32 figure of 90.5 TFLOPS while the Quadro P4000 provides 5.3 TFLOPS. In FP16 dense mode the L40 reaches 181.05 TFLOPS. This FP16 dense value exceeds the FP32 value of the Quadro P4000 by a wide margin and indicates greater throughput for mixed precision operations. Memory bandwidth of 864 GB per second on the L40 versus 243 GB per second on the Quadro P4000 allows larger batch sizes during training or inference because data movement occurs more rapidly. When sparsity is enabled the L40 reaches 362.1 TFLOPS in FP16 with sparsity. The same pattern holds for FP8 dense at 362 TFLOPS and FP8 with sparsity at 724 TFLOPS on the L40. These figures show that the L40 supports higher precision workloads at scale while the Quadro P4000 remains limited to its published FP32 rating.

When to Choose the L40
The L40 suits workloads that require 48 GB of memory and 864 GB per second bandwidth such as large model training or inference. Its FP16 dense rating of 181.05 TFLOPS and FP32 rating of 90.5 TFLOPS provide headroom for scientific computing tasks that benefit from the 300 W TDP envelope. Organizations running FP8 dense operations at 362 TFLOPS select the L40 for throughput advantages over older cards.
When to Choose the Quadro P4000
The Quadro P4000 fits environments constrained to 105 W TDP and 8 GB memory where basic FP32 workloads at 5.3 TFLOPS suffice. Legacy applications that run on Pascal architecture and PCIe 3.0 interconnects continue to use this GPU without requiring newer memory capacity.
Use Cases
The L40 supplies 48 GB memory and FP16 dense performance of 181.05 TFLOPS that support larger models than the 8 GB limit on the Quadro P4000.
FP8 dense throughput of 362 TFLOPS on the L40 enables faster token generation compared with the FP32 only rating of 5.3 TFLOPS on the Quadro P4000.
Memory bandwidth of 864 GB per second on the L40 permits larger batch sizes during fine tuning than the 243 GB per second available on the Quadro P4000.
The L40 FP16 dense figure of 181.05 TFLOPS accelerates image generation steps beyond the capabilities of the Quadro P4000 FP32 rating.
FP32 performance of 90.5 TFLOPS on the L40 handles double precision adjacent workloads more effectively than the 5.3 TFLOPS on the Quadro P4000.
Frequently Asked Questions
What is the memory difference between L40 and Quadro P4000?▾
The L40 contains 48 GB of GDDR6 memory while the Quadro P4000 contains 8 GB of GDDR5 memory. This difference directly affects the size of models that each GPU can load.
How does memory bandwidth compare on these GPUs?▾
The L40 provides 864 GB per second of memory bandwidth whereas the Quadro P4000 provides 243 GB per second. Higher bandwidth supports larger batch processing during compute tasks.
What FP32 performance does each GPU deliver?▾
The L40 lists 90.5 TFLOPS in FP32 and the Quadro P4000 lists 5.3 TFLOPS in FP32. These numbers indicate the baseline single precision throughput for each card.
Does the L40 support sparsity in tensor operations?▾
The L40 lists FP16 with sparsity at 362.1 TFLOPS and FP8 with sparsity at 724 TFLOPS. The Quadro P4000 has no published sparse figures.
Which GPU has the higher TDP rating?▾
The L40 carries a 300 W TDP while the Quadro P4000 carries a 105 W TDP. Power delivery requirements therefore differ between the two cards.
What interconnect does each GPU use?▾
