Performance Analysis
FP16 dense performance measures 18.7 TFLOPS on the P100 whereas FP16 with sparsity performance measures 222.2 TFLOPS on the RTX A5000. The FP32 value of 9.3 TFLOPS on the P100 and 27.8 TFLOPS on the RTX A5000 translate to differences in compute capacity that affect training throughput and inference speed for models limited by these exact figures. Memory bandwidth at 732 GB/s for the P100 and 768 GB/s for the RTX A5000 influences achievable batch sizes during data intensive operations as higher bandwidth supports greater data movement per second without introducing unrelated metrics.

When to Choose the P100
The P100 suits scenarios that utilize its 16 GB HBM2 memory and NVLink interconnect options in SXM2 form factor. Workloads that align with 18.7 TFLOPS FP16 dense and 9.3 TFLOPS FP32 benefit from this configuration when power draw at 250W remains acceptable.
When to Choose the RTX A5000
The RTX A5000 fits cases that require 24 GB GDDR6 memory and PCIe 4.0 interconnect in its form factor. Applications that match 222.2 TFLOPS FP16 with sparsity and 27.8 TFLOPS FP32 gain from the 230W TDP rating in these contexts.
Use Cases
The RTX A5000 delivers 27.8 TFLOPS FP32 and 222.2 TFLOPS FP16 with sparsity that exceed the P100 figures of 9.3 TFLOPS FP32 and 18.7 TFLOPS FP16 dense.
Higher FP16 with sparsity at 222.2 TFLOPS and 24 GB memory on the RTX A5000 support larger inference batches than the P100 specifications allow.
The RTX A5000 768 GB/s bandwidth and 27.8 TFLOPS FP32 enable efficient parameter updates compared to the P100 732 GB/s and 9.3 TFLOPS FP32.
Memory capacity of 24 GB on the RTX A5000 accommodates diffusion model requirements beyond the 16 GB limit of the P100.
The P100 NVLink and SXM2 options align with 18.7 TFLOPS FP16 dense workloads that match established scientific pipelines.

What memory types distinguish the P100 from the RTX A5000?▾
The P100 uses 16 GB HBM2 memory while the RTX A5000 uses 24 GB GDDR6 memory. Bandwidth reaches 732 GB/s on the P100 and 768 GB/s on the RTX A5000.
How do FP32 values compare between these GPUs?▾
FP32 performance stands at 9.3 TFLOPS for the P100 and 27.8 TFLOPS for the RTX A5000. These figures determine general purpose compute capacity in each case.
Which GPU offers higher FP16 throughput?▾
The RTX A5000 provides 222.2 TFLOPS FP16 with sparsity while the P100 provides 18.7 TFLOPS FP16 dense. Direct comparison requires attention to the sparsity label on the higher figure.
What power ratings apply to the P100 and RTX A5000?▾
TDP equals 250W for the P100 and 230W for the RTX A5000. Form factor choices further differentiate power delivery options between the models.
Do both GPUs support NVLink?▾
Both the P100 and the RTX A5000 list NVLink as an interconnect. The P100 adds PCIe 3.0 while the RTX A5000 adds PCIe 4.0.
Which is cheaper to rent, the P100 or the RTX A5000?▾
Cloud rental prices for both the P100 and RTX A5000 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.
