Performance Analysis
The RTX 2080 delivers more than twice the dense FP16 throughput at 40.3 TFLOPS compared to the P100 at 18.7 TFLOPS which translates to faster matrix operations during training and inference steps that rely on half precision. The P100 supplies 1.63 times the memory bandwidth at 732 GB/s versus 448 GB/s which supports larger batch sizes in memory intensive kernels before swapping occurs. FP32 performance remains close with the RTX 2080 at 10 TFLOPS and the P100 at 9.3 TFLOPS so workloads limited to single precision show smaller gains. Higher VRAM on the P100 at 16 GB versus 8 to 11 GB on the RTX 2080 further influences batch sizing in models that exceed the lower capacity limit.

When to Choose the P100
Its 250 W TDP pairs with NVLink interconnect in SXM2 form factor configurations where sustained memory throughput outweighs tensor core density.
When to Choose the RTX 2080
The RTX 2080 fits inference workloads that exploit 40.3 TFLOPS dense FP16 and 161.1 TOPS dense INT8 within a 215 W power envelope. Its PCIe form factor and 10 TFLOPS FP32 rating support compact deployments where newer architecture features align with reduced memory requirements.
Use Cases
The RTX 2080 supplies 40.3 TFLOPS dense FP16 which exceeds the P100 by more than double for accelerated forward and backward passes.
Dense INT8 performance at 161.1 TOPS on the RTX 2080 enables higher throughput than the P100 which lacks a published INT8 rating.
The P100 16 GB memory capacity accommodates larger fine tuning batches than the RTX 2080 8 to 11 GB limit.
The RTX 2080 40.3 TFLOPS dense FP16 rating accelerates diffusion steps compared to the P100 18.7 TFLOPS dense FP16.
The P100 732 GB/s bandwidth supports memory bound scientific kernels better than the RTX 2080 448 GB/s bandwidth.
