A30 vs RTX 3060

Compute performance favors the RTX 3060 slightly, with 12.7 TFLOPS in both FP16 and FP32 versus the A30's 10.3 TFLOPS per precision. This edge suits inference tasks or lighter training where raw throughput matters more than memory. However, the A30's 24 GB HBM2 VRAM doubles the RTX 3060's 12 GB GDDR6, enabling larger batch sizes in model training and reducing out-of-memory errors for datasets exceeding 12 GB.

Memory bandwidth presents the starkest divide: the A30 achieves 933 GB/s compared to 360 GB/s on the RTX 3060. Higher bandwidth accelerates data transfers in memory-bound workloads like LLM fine-tuning, allowing sustained performance with bigger batches. For FP16/FP32 parity on both GPUs, mixed-precision training benefits equally, but the A30 excels in scenarios demanding high data throughput. Power efficiency remains close, with TDPs of 165 W and 170 W respectively.

In real-world terms, the RTX 3060 handles small-to-medium models efficiently due to superior TFLOPS, while the A30 dominates large-scale inference or training requiring extensive VRAM and bandwidth.

Select the A30 for workloads demanding high VRAM capacity, such as training large language models exceeding 12 GB. Its 24 GB HBM2 and 933 GB/s bandwidth support bigger batch sizes without swapping, and NVLink facilitates multi-GPU setups for scaled compute. Enterprise environments benefit from this GPU's datacenter reliability over consumer alternatives.

Opt for the RTX 3060 in budget-sensitive cloud deployments, available from $0.03 per hour across 12 providers. Its 12.7 TFLOPS FP16/FP32 performance outperforms the A30's 10.3 TFLOPS for inference on models fitting within 12 GB GDDR6. Gaming-adjacent tasks or light ML prototyping favor this accessible, power-similar option at 170 W TDP.
