Quadro P4000 vs RTX 5090

The FP32 rating of 5.3 TFLOPS on the Quadro P4000 limits throughput compared with the 104.8 TFLOPS figure on the RTX 5090. For the RTX 5090 the dense FP16 rating reaches 209.5 TFLOPS while the Quadro P4000 provides no published FP16 value. This dense FP16 advantage on the RTX 5090 supports larger batch sizes during training and faster token generation during inference. Memory bandwidth of 1792 GB/s on the RTX 5090 exceeds the 243 GB/s on the Quadro P4000 by a factor of seven allowing the newer card to sustain higher data movement rates. When sparsity is applied the RTX 5090 dense FP16 value of 209.5 TFLOPS scales to 419 TFLOPS with sparsity yet comparisons remain valid only within the same mode.

The Quadro P4000 suits environments where power draw must stay at 105W and where 8 GB GDDR5 meets modest model sizes. Legacy professional applications that run on Pascal architecture avoid migration costs when the 5.3 TFLOPS FP32 rating satisfies requirements. Systems limited to PCIe 3.0 interconnect also align with the Quadro P4000 specifications.

The RTX 5090 fits workloads that require 32 GB GDDR7 and 1792 GB/s bandwidth to handle large batches. Dense FP16 performance at 209.5 TFLOPS accelerates both training and inference relative to the older card. PCIe 5.0 support and the 104.8 TFLOPS FP32 rating further benefit compute intensive tasks.
