Performance Analysis
Dense FP16 performance reaches 165.2 TFLOPS on the RTX 4090 and 503.8 TFLOPS on the RTX PRO 6000. The FP16 to FP32 ratio equals 2.0 on the RTX 4090 and 4.0 on the RTX PRO 6000. Higher dense FP16 throughput combined with 1792 GB/s bandwidth on the RTX PRO 6000 supports larger batch sizes during both training and inference workloads. With sparsity the FP16 figures become 330.4 TFLOPS versus 1007.6 TFLOPS. Memory bandwidth of 1008 GB/s on the RTX 4090 limits maximum concurrent data movement compared with 1792 GB/s on the RTX PRO 6000.

When to Choose the RTX 4090
The RTX 4090 suits workloads that fit within 24 GB VRAM and require only 450W TDP. Scientific computing tasks that rely on 82.6 TFLOPS FP32 can proceed without excess power draw. Users who need PCIe 4.0 interconnect rather than PCIe 5.0 find the RTX 4090 sufficient for stable diffusion jobs that do not exceed its memory capacity.
When to Choose the RTX PRO 6000
The RTX PRO 6000 suits workloads that require 96 GB VRAM and dense FP16 throughput of 503.8 TFLOPS. Inference pipelines gain from FP8 dense performance of 1007.6 TFLOPS when model scale exceeds 24 GB limits.
Use Cases
The RTX PRO 6000 provides 96 GB VRAM against 24 GB and 503.8 TFLOPS dense FP16 against 165.2 TFLOPS.
The RTX PRO 6000 supplies 1007.6 TFLOPS dense FP8 and 1792 GB/s bandwidth for larger concurrent batches.
The RTX 4090 meets typical image generation needs inside 24 GB VRAM at 450W TDP.
The RTX 4090 delivers 82.6 TFLOPS FP32 at lower 450W TDP while the RTX PRO 6000 delivers 126 TFLOPS FP32 when higher precision throughput is required.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 4090 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.
