Performance Analysis
Dense FP16 performance reaches 57 TFLOPS on the Quadro RTX 4000 and 71 TFLOPS on the RTX 3090 so the RTX 3090 completes dense FP16 operations at a higher rate than the Quadro RTX 4000. FP32 figures of 7.1 TFLOPS versus 35.6 TFLOPS indicate the RTX 3090 processes FP32 workloads at five times the throughput of the Quadro RTX 4000. Memory bandwidth of 416 GB/s on the Quadro RTX 4000 versus 936 GB/s on the RTX 3090 allows the RTX 3090 to sustain larger batch sizes during training or inference steps that move substantial data volumes. The 8 GB capacity on the Quadro RTX 4000 restricts model sizes compared with the 24 GB capacity on the RTX 3090 in memory intensive tasks.

When to Choose the Quadro RTX 4000
The Quadro RTX 4000 suits deployments where TDP must remain at 125W and PCIe 3.0 interconnect is sufficient. Its 8 GB memory and 416 GB/s bandwidth support lighter workloads that do not exceed these limits while maintaining lower overall power draw than the 350W TDP of the RTX 3090.
When to Choose the RTX 3090
The RTX 3090 fits scenarios that require 24 GB memory and 936 GB/s bandwidth along with dense FP16 at 71 TFLOPS or FP32 at 35.6 TFLOPS. Its NVLink support and PCIe 4.0 interconnect further enable configurations that benefit from higher interconnect speeds than the PCIe 3.0 limit of the Quadro RTX 4000.
Use Cases
The RTX 3090 provides 24 GB memory and 35.6 TFLOPS FP32 compared with 8 GB and 7.1 TFLOPS on the Quadro RTX 4000 allowing larger models to fit and train faster.
Dense FP16 at 71 TFLOPS and 936 GB/s bandwidth on the RTX 3090 exceed the 57 TFLOPS and 416 GB/s on the Quadro RTX 4000 supporting higher throughput inference.
24 GB capacity and 35.6 TFLOPS FP32 on the RTX 3090 handle fine tuning workloads that exceed the 8 GB and 7.1 TFLOPS limits of the Quadro RTX 4000.
The RTX 3090 memory bandwidth of 936 GB/s and 24 GB capacity enable larger batch processing than the 416 GB/s and 8 GB on the Quadro RTX 4000.
FP32 performance of 35.6 TFLOPS and memory bandwidth of 936 GB/s on the RTX 3090 surpass the 7.1 TFLOPS and 416 GB/s of the Quadro RTX 4000 for compute heavy simulations.
