L4 vs Quadro RTX 4000

The L4 FP16 dense figure of 121 TFLOPS exceeds the Quadro RTX 4000 FP16 dense figure of 57 TFLOPS by a factor derived directly from those two numbers. This gap indicates that the L4 can process FP16 dense operations more than twice as fast as the Quadro RTX 4000 during inference or training steps that rely on dense FP16. The L4 FP32 value of 30.3 TFLOPS likewise exceeds the Quadro RTX 4000 FP32 value of 7.1 TFLOPS. Memory bandwidth stands at 300 GB/s on the L4 versus 416 GB/s on the Quadro RTX 4000 so the Quadro RTX 4000 may sustain larger batch sizes in bandwidth limited kernels even though its VRAM capacity remains lower at 8 GB. The L4 also lists FP16 with sparsity at 242 TFLOPS while the Quadro RTX 4000 lists no sparsity figure for FP16.

The L4 suits workloads that require the listed 24 GB VRAM capacity together with the 121 TFLOPS FP16 dense rating. Its 72W TDP allows deployment in power constrained servers where the Quadro RTX 4000 125W TDP would exceed limits. The L4 PCIe 4.0 interconnect further supports higher throughput in compatible systems.

The Quadro RTX 4000 suits workloads that benefit from its 416 GB/s memory bandwidth when operating within the 8 GB VRAM limit. Its Turing architecture may align with legacy software stacks that do not yet support Ada Lovelace features listed for the L4.
