Performance Analysis
The FP32 performance stands at 9.3 TFLOPS for the P100 and 19.2 TFLOPS for the A4000 so the A4000 delivers higher throughput in dense floating point workloads. Memory bandwidth reaches 732 GB/s on the P100 compared with 448 GB/s on the A4000 which allows the P100 to sustain larger batch sizes in memory bound operations. FP16 dense performance measures 18.7 TFLOPS on the P100 while the A4000 reports FP16 with sparsity at 153.4 TFLOPS so direct ratios remain limited to matching categories such as dense FP32 figures.

When to Choose the P100
The P100 suits workloads that require 732 GB/s memory bandwidth and NVLink interconnect such as certain scientific computing tasks that move large data volumes across multiple GPUs. Its 16 GB HBM2 configuration and 250W TDP also align with established systems that already support SXM2 or PCIe 3.0 form factors.
When to Choose the RTX A4000
The A4000 fits environments that prioritize 140W TDP and PCIe 4.0 connectivity along with 19.2 TFLOPS FP32 performance for single GPU inference or fine tuning jobs. Its 16 to 20 GB GDDR6 memory and Ampere architecture support newer software stacks that benefit from the listed 153.4 TFLOPS FP16 with sparsity figure.
Use Cases
The A4000 supplies 19.2 TFLOPS FP32 which exceeds the 9.3 TFLOPS FP32 of the P100.
The A4000 lists FP16 with sparsity at 153.4 TFLOPS and operates at 140W TDP.
The A4000 provides 19.2 TFLOPS FP32 in a 140W envelope with PCIe 4.0 support.
The A4000 delivers 19.2 TFLOPS FP32 and 448 GB/s bandwidth at lower power than the P100.
The P100 reaches 732 GB/s memory bandwidth and includes NVLink interconnect.
