Performance Analysis
The RTX 4090 delivers 165.2 TFLOPS dense FP16 compared with the P100 at 18.7 TFLOPS dense FP16 for an 8.8 times advantage in dense FP16 throughput. The same ratio appears in FP32 where the RTX 4090 reaches 82.6 TFLOPS against the P100 at 9.3 TFLOPS. Higher dense FP16 throughput on the RTX 4090 allows larger batch sizes during training or faster token generation during inference when memory capacity permits. The RTX 4090 also supplies 1008 GB/s memory bandwidth against 732 GB/s on the P100 which supports 1.4 times greater data movement per second and therefore sustains larger batches before memory bandwidth saturates.

When to Choose the P100
The P100 suits scientific computing jobs that run on existing NVLink equipped systems and require only 16 GB memory. Its 250 W TDP fits power constrained servers where the 450 W TDP of the RTX 4090 would exceed limits. Workloads that already achieve acceptable throughput at 18.7 TFLOPS dense FP16 gain no benefit from migration.
When to Choose the RTX 4090
Its 1008 GB/s bandwidth supports larger batch sizes than the 732 GB/s available on the P100. New deployments without legacy NVLink requirements favor the RTX 4090 for its higher dense FP16 and FP32 throughput.
Use Cases
The RTX 4090 supplies 165.2 TFLOPS dense FP16 and 24 GB memory which exceed the 18.7 TFLOPS dense FP16 and 16 GB memory of the P100.
The RTX 4090 reaches 165.2 TFLOPS dense FP16 allowing higher throughput than the P100 at 18.7 TFLOPS dense FP16.
The RTX 4090 provides 24 GB memory and 165.2 TFLOPS dense FP16 which accommodate larger models than the P100 configuration.
The P100 operates at 250 W TDP and supports NVLink interconnects that match existing scientific computing clusters.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the P100 and the RTX 4090. Dense and sparse throughput are listed separately.
- Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
- The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
