Performance Analysis
Dense FP16 performance on the MI250X reaches 383 TFLOPS while the A30 reaches 165 TFLOPS. This gap indicates the MI250X can complete matrix operations in training loops more than twice as fast when both GPUs run dense workloads. Memory bandwidth of 3277 GB/s on the MI250X versus 933 GB/s on the A30 permits larger batch sizes before data movement stalls occur. FP32 throughput of 47.9 TFLOPS on the MI250X versus 10.3 TFLOPS on the A30 further widens the advantage for scientific kernels that stay in single precision.

When to Choose the A30
The A30 suits environments that require a 165 W power envelope and PCIe connectivity. Its 24 GB capacity and 330 TOPS dense INT8 rating fit inference pipelines that process moderate batch volumes without exceeding rack power limits.
When to Choose the MI250X
The MI250X suits workloads that demand 128 GB capacity and 3277 GB/s bandwidth. Its 383 TFLOPS dense FP16 rating and 47.9 TFLOPS FP32 rating accelerate large model training and memory intensive simulations that exceed the limits of smaller accelerators.
Use Cases
The MI250X 128 GB capacity and 383 TFLOPS dense FP16 rating support larger models than the A30 24 GB limit.
The A30 165 W TDP and 330 TOPS dense INT8 rating fit power constrained inference servers.
The MI250X 3277 GB/s bandwidth accommodates the activation memory required for fine tuning runs.
Both GPUs deliver sufficient dense FP16 throughput for image generation workloads at moderate resolutions.
The MI250X 47.9 TFLOPS FP32 rating processes double precision scientific codes faster than the A30 10.3 TFLOPS rating.
