Performance Analysis
The RTX 4090 delivers 82.6 TFLOPS of FP32 performance while the Quadro P4000 delivers 5.3 TFLOPS of FP32 performance. This produces a ratio of approximately 15.6 times higher FP32 throughput on the RTX 4090. The RTX 4090 also provides dense FP16 performance of 165.2 TFLOPS compared with no published dense FP16 figure for the Quadro P4000. Memory bandwidth of 1008 GB per second on the RTX 4090 versus 243 GB per second on the Quadro P4000 supports larger batch sizes during training or inference by allowing faster data movement between memory and compute units. Dense FP16 throughput of 165.2 TFLOPS on the RTX 4090 enables faster matrix operations than the 5.3 TFLOPS FP32 limit on the Quadro P4000 when sparsity is not applied.

When to Choose the Quadro P4000
The Quadro P4000 suits environments constrained by a 105W TDP limit where the 450W TDP of the RTX 4090 exceeds power budgets. Its PCIe 3.0 interconnect matches older server platforms that lack PCIe 4.0 support. Workloads that require only 8 GB of memory and remain below 5.3 TFLOPS of FP32 throughput complete without the need for additional hardware.
When to Choose the RTX 4090
Its 1008 GB per second bandwidth supports larger batch sizes than the 243 GB per second available on the Quadro P4000. Dense FP16 performance of 165.2 TFLOPS accelerates both training and inference relative to the Quadro P4000 FP32 ceiling of 5.3 TFLOPS.
Use Cases
The RTX 4090 supplies 24 GB memory and 82.6 TFLOPS FP32 performance that exceed the 8 GB and 5.3 TFLOPS FP32 of the Quadro P4000.
