Performance Analysis
Dense FP16 performance reaches 18.7 TFLOPS on the P100 and 71 TFLOPS on the RTX 3090. This gap indicates that training and inference steps complete faster on the RTX 3090 when models fit within memory limits. FP32 performance follows the same pattern at 9.3 TFLOPS for the P100 and 35.6 TFLOPS for the RTX 3090. Memory bandwidth of 732 GB/s on the P100 versus 936 GB/s on the RTX 3090 influences maximum batch sizes during large tensor operations. The RTX 3090 also lists dense INT8 at 284 TOPS. Higher bandwidth on the RTX 3090 supports larger batches before memory capacity of 24 GB becomes the limit compared with 16 GB on the P100.

When to Choose the P100
The P100 suits scientific computing workloads that operate within 16 GB HBM2 and require 18.7 TFLOPS dense FP16. Its 250W TDP reduces power draw in sustained runs. NVLink interconnect remains available for multi GPU scaling where PCIe 3.0 suffices.
When to Choose the RTX 3090
Its 936 GB/s bandwidth allows larger batches than the P100 in memory bound scenarios. PCIe 4.0 interconnect supports newer host systems.
Use Cases
The RTX 3090 supplies 71 TFLOPS dense FP16 and 24 GB memory for larger models.
Dense FP16 at 71 TFLOPS and 936 GB/s bandwidth support higher throughput than the P100.
24 GB GDDR6X and 35.6 TFLOPS FP32 allow bigger batch sizes than 16 GB on the P100.
The RTX 3090 provides 71 TFLOPS dense FP16 and 936 GB/s bandwidth for image generation workloads.
The P100 delivers 9.3 TFLOPS FP32 at 250W TDP with NVLink for multi node scaling.
