A40 vs RTX PRO 6000

The FP16 dense figure of 503.8 TFLOPS on the RTX PRO 6000 exceeds the 149.7 TFLOPS dense figure on the A40 by a factor of 3.36 while the corresponding FP32 values maintain a similar 3.37 ratio. This arithmetic gap directly scales training step times and inference throughput for models that remain compute bound. When sparsity is enabled the RTX PRO 6000 reaches 1007.6 TFLOPS FP16 with sparsity against 299.4 TFLOPS FP16 with sparsity on the A40 preserving the same relative advantage. The 600 W TDP of the RTX PRO 6000 versus the 300 W TDP of the A40 further indicates that sustained dense workloads will require additional power and cooling infrastructure.

The A40 suits deployments where total power draw must stay at 300 W and existing Ampere software stacks already deliver acceptable throughput. Its 48 GB capacity remains sufficient for inference batches that fit within that limit and its 149.7 TFLOPS dense FP16 rating supports moderate-scale scientific computing kernels without requiring platform upgrades.

The RTX PRO 6000 suits workloads that require 96 GB capacity or FP16 dense throughput above 149.7 TFLOPS. Its 1792 GB/s bandwidth supports larger batches in fine-tuning and its 503.8 TFLOPS dense FP16 rating shortens iteration times for large language model training relative to the A40.
