Performance Analysis
The RTX 3090 family delivers 71 TFLOPS FP16 dense performance and 35.6 TFLOPS FP32 while the RTX 5070 Ti family delivers 61.7 TFLOPS FP16 dense performance and 30.9 TFLOPS FP32. This FP16 to FP32 ratio supports mixed precision training on both families yet the higher absolute numbers on the RTX 3090 family allow larger batch sizes when memory bandwidth reaches 936 GB/s versus 672 GB/s on the RTX 5070 Ti family. Sparse FP16 figures of 142 TFLOPS on the RTX 3090 family and 123.5 TFLOPS on the RTX 5070 Ti family follow the same pattern for inference workloads that exploit sparsity.

When to Choose the RTX 3090
The RTX 3090 variant suits workloads that require 24 GB memory capacity and 936 GB/s bandwidth for larger batch sizes during training. NVLink interconnect on this variant enables multi GPU scaling that the PCIe 5.0 interconnect on the RTX 5070 Ti variant does not provide.
When to Choose the RTX 5070 Ti
The RTX 5070 Ti variant fits deployments where 250W TDP reduces power draw compared with 350W TDP on the RTX 3090 variant. PCIe 5.0 interconnect and Blackwell architecture support newer system platforms that prioritize lower energy use over maximum memory capacity.
Use Cases
The RTX 3090 variant supplies 24 GB memory that accommodates larger models than the 16 GB on the RTX 5070 Ti variant.
Higher 936 GB/s bandwidth on the RTX 3090 family supports larger batch sizes than 672 GB/s on the RTX 5070 Ti family.
24 GB capacity on the RTX 3090 variant handles fine tuning datasets that exceed the 16 GB limit of the RTX 5070 Ti variant.
The RTX 3090 variant memory bandwidth of 936 GB/s enables faster image generation iterations than 672 GB/s on the RTX 5070 Ti variant.
FP32 performance of 35.6 TFLOPS on the RTX 3090 family exceeds 30.9 TFLOPS on the RTX 5070 Ti family for compute heavy simulations.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the RTX 3090 and the RTX 5070 Ti. 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.
