Performance Analysis

The L40 achieves 181.05 TFLOPS in dense FP16 and 90.5 TFLOPS in FP32 whereas the RTX A5000 lists 222.2 TFLOPS in FP16 with sparsity and 27.8 TFLOPS in FP32. Sparse FP16 performance reaches 362.1 TFLOPS on the L40 against 222.2 TFLOPS on the RTX A5000. The higher memory bandwidth of 864 GB/s on the L40 versus 768 GB/s on the RTX A5000 supports larger batch sizes during training and inference operations that move substantial data volumes between memory and compute units.

When to Choose the L40

The L40 suits scenarios that require 48 GB VRAM and 90.5 TFLOPS FP32 throughput for large model handling. Its 864 GB/s bandwidth and dense FP16 rating of 181.05 TFLOPS further support intensive compute tasks where the 300W TDP remains acceptable.

When to Choose the RTX A5000

The RTX A5000 fits deployments that prioritize the 230W TDP and NVLink interconnect option alongside 24 GB VRAM. Its FP16 performance with sparsity at 222.2 TFLOPS meets needs in environments where lower power draw takes precedence over peak dense throughput figures.

Frequently Asked Questions

How does FP32 performance compare on these GPUs?▾

The L40 reaches 90.5 TFLOPS in FP32. The RTX A5000 reaches 27.8 TFLOPS in FP32. The ratio favors the L40 by more than three times.

Which GPU has higher memory bandwidth?▾

The L40 lists 864 GB/s memory bandwidth. The RTX A5000 lists 768 GB/s memory bandwidth. The L40 therefore sustains higher data movement rates.

What are the TDP values for L40 and RTX A5000?▾

The L40 requires 300W TDP. The RTX A5000 requires 230W TDP. Lower power draw on the RTX A5000 reduces cooling demands in dense installations.

Does the RTX A5000 support NVLink?▾

The RTX A5000 includes NVLink interconnect support. The L40 relies on PCIe 4.0 interconnect only. Multi-GPU scaling options therefore differ between the two.

Which is cheaper to rent, the L40 or the RTX A5000?▾

Cloud rental prices for both the L40 and RTX A5000 vary by provider, configuration, and availability. This page shows live pricing from 25+ providers updated every 60 seconds. Scroll to the Live Cloud Pricing section to compare current rates.

How much VRAM does the L40 have compared to the RTX A5000?▾

The L40 has 48 GB of GDDR6 memory. The RTX A5000 has 24 GB of GDDR6 memory.

Can I find L40 and RTX A5000 GPUs available to rent right now?▾

Yes. This page shows real-time availability across 25+ cloud GPU providers. The Live Cloud Pricing section displays only in-stock offers with current pricing.

What is the main difference between the L40 and the RTX A5000?▾

The L40 uses the Ada Lovelace architecture (2023) while the RTX A5000 uses Ampere (2021). The L40 has 48 GB of GDDR6 at 864 GB/s; the RTX A5000 has 24 GB of GDDR6 at 768 GB/s, so the L40 has 1.1x the memory bandwidth of the RTX A5000.

How this page is made

  • Specifications come from the NVIDIA, AMD and Intel datasheets for the L40 and the RTX A5000. 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.
