Performance Analysis

FP16 dense performance reaches 57 TFLOPS on the Quadro RTX 4000. FP16 performance with sparsity reaches 153.4 TFLOPS on the RTX A4000. The FP32 delta of 7.1 TFLOPS versus 19.2 TFLOPS indicates the RTX A4000 processes single precision workloads at a higher rate. Memory bandwidth of 416 GB/s on the Quadro RTX 4000 versus 448 GB/s on the RTX A4000 influences achievable batch sizes during tensor operations. Training and inference tasks benefit from the higher FP32 rating and increased bandwidth on the RTX A4000 when sparsity is applicable.

When to Choose the Quadro RTX 4000

The Quadro RTX 4000 suits environments constrained by a 125W TDP limit. Its 8 GB GDDR6 capacity and 416 GB/s bandwidth fit workloads that do not require the larger memory pool of newer cards. PCIe 3.0 interconnect matches systems without PCIe 4.0 support.

When to Choose the RTX A4000

The RTX A4000 fits scenarios needing 16-20 GB GDDR6 and 448 GB/s bandwidth for larger datasets. Its 19.2 TFLOPS FP32 rating and PCIe 4.0 interconnect accelerate data movement in Ampere based servers. The 140W TDP remains acceptable where power budgets allow the performance gain over 7.1 TFLOPS FP32.
