Performance Analysis
The RTX A4000 provides 19.2 TFLOPS FP32 compared to 5.3 TFLOPS FP32 on the Quadro P4000. This FP32 difference allows the RTX A4000 to complete dense matrix operations more than three times faster in training and inference tasks. The RTX A4000 also provides 153.4 TFLOPS FP16 with sparsity while the Quadro P4000 figure remains unpublished by the vendor. Memory bandwidth on the RTX A4000 reaches 448 GB/s against 243 GB/s on the Quadro P4000. Higher bandwidth supports larger batch sizes during model execution without swapping data to host memory.

When to Choose the Quadro P4000
The Quadro P4000 suits environments where power draw must stay at 105W and PCIe 3.0 compatibility is required. Its 8 GB GDDR5 configuration fits workloads that do not exceed this VRAM limit and where FP32 performance at 5.3 TFLOPS meets baseline needs.
When to Choose the RTX A4000
The RTX A4000 suits workloads that require 16-20 GB GDDR6 VRAM and 448 GB/s memory bandwidth. Its 19.2 TFLOPS FP32 and 153.4 TFLOPS FP16 with sparsity accelerate dense and sparse tensor operations beyond the Quadro P4000 limits.
Use Cases
The RTX A4000 supplies 16-20 GB VRAM and 448 GB/s bandwidth that exceed the Quadro P4000 limits of 8 GB and 243 GB/s.
The RTX A4000 delivers 19.2 TFLOPS FP32 and 153.4 TFLOPS FP16 with sparsity against the Quadro P4000 5.3 TFLOPS FP32.
The RTX A4000 448 GB/s bandwidth supports larger batch sizes than the Quadro P4000 243 GB/s bandwidth.
The RTX A4000 16-20 GB VRAM accommodates models that exceed the Quadro P4000 8 GB capacity.
The Quadro P4000 at 105W TDP fits power-constrained nodes while the RTX A4000 at 19.2 TFLOPS FP32 fits performance nodes.
