Performance Analysis
The GTX 1080 Ti's 11.3 TFLOPS FP16 and FP32 rating outpaces the P100's 9.3 TFLOPS: this advantage accelerates training and inference cycles for FP32-dominant workloads like fine-tuning where compute density matters. Both GPUs handle FP16 at matching FP32 rates, supporting mixed-precision training without tensor core penalties. Memory differences prove critical: the P100's 732 GB/s bandwidth and 16 GB HBM2 allow larger batch sizes in training compared to the GTX 1080 Ti's 484 GB/s and 11 GB GDDR5X, minimizing data starvation in memory-bound inference. The P100's NVLink interconnect enables faster multi-GPU communication, unlike the GTX 1080 Ti's PCIe-only setup, benefiting scaled deployments.

When to Choose the GTX 1080 Ti
The GTX 1080 Ti stands out for single-GPU tasks prioritizing raw compute: its 11.3 TFLOPS FP16 and FP32 deliver quicker iterations in inference or fine-tuning of models under 11 GB VRAM at $0.60 per hour. Lower form factor needs fit PCIe slots without SXM2 requirements. Efficiency at 250 W TDP matches smaller cloud instances.
When to Choose the Tesla P100
The P100 fits memory-intensive applications: 16 GB HBM2 VRAM accommodates larger models than the GTX 1080 Ti's 11 GB limit, while 732 GB/s bandwidth sustains high batch sizes in training. NVLink supports multi-GPU scaling absent in the GTX 1080 Ti. Datacenter form factors like SXM2 suit enterprise clouds.
Use Cases
P100's 16 GB HBM2 VRAM and 732 GB/s bandwidth manage larger models and batches superior to GTX 1080 Ti's 11 GB GDDR5X and 484 GB/s.
GTX 1080 Ti's 11.3 TFLOPS FP32 suits small models; P100's extra VRAM aids larger ones at same $0.60/hr pricing.
