Performance Analysis

Dense FP16 performance measures 71 TFLOPS on the RTX 3090 against 503.8 TFLOPS on the RTX PRO 6000. Training and inference operations using dense FP16 therefore advance more rapidly on the RTX PRO 6000. FP16 with sparsity reaches 142 TFLOPS versus 1007.6 TFLOPS and preserves the identical ratio for workloads that apply sparsity. Memory bandwidth at 936 GB/s on the RTX 3090 versus 1792 GB/s on the RTX PRO 6000 permits larger batch sizes during memory intensive operations on the second GPU. FP32 performance at 35.6 TFLOPS compared with 126 TFLOPS adds further distinction for single precision calculations. TDP values of 350W and 600W influence choices for continuous deployment.

When to Choose the RTX 3090

The RTX 3090 fits workloads constrained to 24 GB memory and 936 GB/s bandwidth. Its 350W TDP supports deployments where power limits take priority over the 503.8 TFLOPS dense FP16 available on the alternative. FP32 performance at 35.6 TFLOPS suffices for tasks that remain within these bounds.

When to Choose the RTX PRO 6000

The RTX PRO 6000 addresses applications that require 96 GB memory and 1792 GB/s bandwidth. Dense FP16 performance at 503.8 TFLOPS enables handling of larger models than the 71 TFLOPS specification on the RTX 3090. Its 126 TFLOPS FP32 rating extends capability for precision sensitive computations.

How this page is made

  • Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3090 and the RTX PRO 6000. Dense and sparse throughput are listed separately.
  • Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
  • The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
