Performance Analysis
Dense FP16 performance on the L4 reaches 121 TFLOPS compared with 65 TFLOPS dense FP16 on the T4. This gap allows the L4 to complete matrix operations in fewer cycles during both training and inference passes. The L4 also lists FP16 with sparsity at 242 TFLOPS while the T4 provides no sparsity figure for FP16. Memory bandwidth of 300 GB/s on the L4 versus 320 GB/s on the T4 influences the maximum batch size that fits within available throughput during data movement. INT8 dense performance equals 242 TOPS on the L4 against 130 TOPS on the T4. FP8 dense on the L4 measures 242 TFLOPS with no corresponding figure published for the T4.

When to Choose the L4
The L4 suits workloads that require 24 GB of VRAM and 121 TFLOPS dense FP16. Its 30.3 TFLOPS FP32 rating supports scientific computing tasks that exceed the 8.1 TFLOPS available on the T4. The L4 also supplies INT8 dense at 242 TOPS for quantized inference pipelines.
When to Choose the T4
The T4 fits deployments where 320 GB/s memory bandwidth supports data movement at a 70W TDP. Its 16 GB VRAM capacity remains adequate for smaller inference batches that do not need the 24 GB present on the L4.
Use Cases
