Performance Analysis

The RTX 4090 delivers 82.6 TFLOPS in FP32 while the RTX 4000 Ada Generation GPU delivers 26.7 TFLOPS in FP32. The RTX 4090 also supplies 165.2 TFLOPS in dense FP16 and 330.4 TFLOPS in FP16 with sparsity. The RTX 4000 Ada Generation GPU supplies 427.6 TFLOPS in FP8 with sparsity while the RTX 4090 supplies 330.3 TFLOPS in dense FP8 and 660.6 TFLOPS in FP8 with sparsity. Higher memory bandwidth on the RTX 4090 at 1008 GB per second versus 360 GB per second on the RTX 4000 Ada Generation GPU supports larger batch sizes during training and inference. The 450 W TDP of the RTX 4090 versus the 130 W TDP of the RTX 4000 Ada Generation GPU indicates greater power draw for the higher throughput figures.

How this page is made

  • Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 4000 Ada and the RTX 4090. 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.
