Performance Analysis
The P100 provides dense FP16 performance rated at 18.7 TFLOPS while the GTX 1080 carries no published FP16 figure. This specification gap indicates that the P100 executes half precision operations during training and inference where the GTX 1080 cannot rely on vendor published dense FP16 capability. Memory bandwidth of 732 GB/s on the P100 versus 320 GB/s on the GTX 1080 directly influences batch sizes because higher bandwidth accommodates larger data transfers per cycle in memory bound workloads. FP32 figures remain close at 8.9 TFLOPS for the GTX 1080 and 9.3 TFLOPS for the P100 so single precision tasks show limited differentiation from the raw compute numbers alone.

When to Choose the GTX 1080
The GTX 1080 fits workloads constrained by power limits because its TDP of 180W stays below the 250W TDP of the P100. FP32 centric applications can use the GTX 1080 given its 8.9 TFLOPS FP32 rating that sits near the P100 9.3 TFLOPS FP32 rating. PCIe only environments also align with the GTX 1080 interconnect specification.
When to Choose the P100
The P100 serves tasks that require dense FP16 throughput at the published 18.7 TFLOPS level or memory capacity of 16 GB HBM2. Bandwidth at 732 GB/s further supports the P100 when batch sizes exceed what 320 GB/s on the GTX 1080 can sustain. NVLink availability on the P100 also enables multi GPU scaling beyond PCIe 3.0 limits.
Use Cases
The P100 supplies dense FP16 at 18.7 TFLOPS together with 16 GB memory which exceeds GTX 1080 published capabilities.
Dense FP16 performance of 18.7 TFLOPS on the P100 enables higher throughput than the GTX 1080 with no published FP16 figure.
The P100 732 GB/s bandwidth and 16 GB HBM2 memory allow larger batch sizes than the GTX 1080 320 GB/s and 8 GB GDDR5X.
FP32 ratings of 8.9 TFLOPS on the GTX 1080 and 9.3 TFLOPS on the P100 remain comparable for this workload.
The P100 provides 9.3 TFLOPS FP32 along with NVLink support absent from the GTX 1080 PCIe only design.
Frequently Asked Questions
What FP32 performance do the GTX 1080 and P100 deliver?▾
The GTX 1080 reaches 8.9 TFLOPS FP32. The P100 reaches 9.3 TFLOPS FP32. These figures come directly from the published specifications for each GPU.
Does the P100 support dense FP16?▾
The P100 lists dense FP16 performance at 18.7 TFLOPS. The GTX 1080 carries no published FP16 value. This difference affects half precision training and inference workloads.
How does memory bandwidth compare between these GPUs?▾
The GTX 1080 provides 320 GB/s bandwidth. The P100 provides 732 GB/s bandwidth. Higher bandwidth on the P100 supports larger batch sizes in bandwidth limited applications.
What are the TDP values for the GTX 1080 and P100?▾
The GTX 1080 TDP equals 180W. The P100 TDP equals 250W. Power consumption therefore differs by 70W between the two models.
Which interconnects does each GPU support?▾
The GTX 1080 supports only PCIe 3.0. The P100 supports both NVLink and PCIe 3.0. Multi GPU scaling options therefore expand on the P100.
Which is cheaper to rent, the GTX 1080 or the P100?▾
Cloud rental prices for both the GTX 1080 and P100 vary by provider, configuration, and availability. This page shows live pricing from 25+ providers updated every 60 seconds. Scroll to the Live Cloud Pricing section to compare current rates.
How much VRAM does the GTX 1080 have compared to the P100?▾
The GTX 1080 has 8 to 11 GB of GDDR5X memory. The P100 has 16 GB of HBM2 memory.
Can I find GTX 1080 and P100 GPUs available to rent right now?▾
Yes. This page shows real-time availability across 25+ cloud GPU providers. The Live Cloud Pricing section displays only in-stock offers with current pricing.
What is the main difference between the GTX 1080 and the P100?▾
The GTX 1080 uses the Pascal architecture (2016) while the P100 uses Pascal (2016). The GTX 1080 has 8-11 GB of GDDR5X at 320 GB/s; the P100 has 16 GB of HBM2 at 732 GB/s, so the P100 has 2.3x the memory bandwidth of the GTX 1080.
