L4 vs MI250X

Specifications and current cloud pricing, side by side.

Ada LovelacevsCDNA 2Updated 34 days ago

The MI250X wins for the most common use case of LLM training because its 383 TFLOPS dense FP16 and 128 GB memory exceed the L4 specifications by wide margins despite higher TDP.

Performance Analysis

Dense FP16 performance places the MI250X at 383 TFLOPS against the L4 at 121 TFLOPS for a ratio exceeding three times. This gap translates to shorter training runtimes on the MI250X when dense FP16 operations dominate workloads. The L4 lists dense FP32 at 30.3 TFLOPS while the MI250X lists dense FP32 at 47.9 TFLOPS so inference latency benefits remain smaller than training gains. Memory bandwidth of 3277 GB/s on the MI250X versus 300 GB/s on the L4 supports substantially larger batch sizes before memory capacity of 128 GB versus 24 GB becomes limiting.

When to Choose the L4

The L4 suits deployments where TDP stays at 72W and PCIe form factor fits existing servers. Its dense INT8 rating of 242 TOPS meets many inference pipelines without requiring the 560W TDP of the MI250X.

When to Choose the MI250X

The MI250X suits workloads that require 128 GB memory and 3277 GB/s bandwidth such as large model training. Its dense FP16 rating of 383 TFLOPS accelerates those sessions beyond the 121 TFLOPS dense FP16 of the L4.
