Performance Analysis
The L4 delivers FP16 dense performance of 121 TFLOPS compared to the RTX A4500 FP16 figure of 19.2 TFLOPS while the L4 also provides FP32 performance of 30.3 TFLOPS against the RTX A4500 FP32 performance of 19.2 TFLOPS. This FP16 dense to FP16 dense delta allows the L4 to complete matrix operations in training and inference workloads at substantially higher throughput than the RTX A4500. Memory bandwidth stands at 300 GB/s for the L4 family and 448 GB/s for the RTX A4500 family so the RTX A4500 supports larger batch sizes in bandwidth limited scenarios despite its lower tensor throughput.

When to Choose the L4
The L4 variant suits environments that prioritize power efficiency at 72W TDP together with 24 GB memory capacity and FP16 dense throughput of 121 TFLOPS. Workloads that run continuously benefit from the reduced power draw and the higher dense tensor performance relative to the RTX A4500.
When to Choose the RTX A4500
The RTX A4500 variant fits applications that require memory bandwidth of 448 GB/s and can tolerate TDP of 140W with 20 GB memory capacity. Scenarios where data movement dominates over tensor calculations gain from the bandwidth advantage over the L4.
Use Cases
The L4 provides 121 TFLOPS FP16 dense performance and 24 GB memory which exceed the RTX A4500 capabilities for large model training.
FP16 dense throughput of 121 TFLOPS on the L4 accelerates token generation compared to 19.2 TFLOPS on the RTX A4500.
The L4 24 GB capacity and 30.3 TFLOPS FP32 performance support parameter updates more effectively than the RTX A4500.
Memory bandwidth of 448 GB/s on the RTX A4500 improves image generation throughput over the L4 300 GB/s figure.
FP32 performance of 30.3 TFLOPS on the L4 and 19.2 TFLOPS on the RTX A4500 both handle simulation workloads adequately.
