Performance Analysis
The RTX 4090 family delivers 165.2 TFLOPS FP16 dense compared with 61.7 TFLOPS FP16 dense on the RTX 5070 Ti family. The same families report 330.4 TFLOPS FP16 with sparsity versus 123.5 TFLOPS FP16 with sparsity. FP32 performance reaches 82.6 TFLOPS on the RTX 4090 family and 30.9 TFLOPS on the RTX 5070 Ti family. Higher memory bandwidth of 1008 GB/s on the RTX 4090 family versus 672 GB/s on the RTX 5070 Ti family supports larger batch sizes during training and inference. The FP16 dense to FP32 ratio equals 2.0 on both families indicating consistent scaling for mixed precision workloads.

When to Choose the RTX 4090
The RTX 4090 variant suits workloads that require the 24 GB memory capacity and 1008 GB/s bandwidth of its family. Applications needing higher dense INT8 throughput of 660.6 TOPS also align with the RTX 4090 variant.
When to Choose the RTX 5070 Ti
The RTX 5070 Ti variant fits deployments where the 250 W TDP and PCIe 5.0 interconnect reduce power and interface constraints. Tasks that operate within 16 GB memory and 61.7 TFLOPS FP16 dense meet requirements on this model. Lower TDP enables denser hardware packing when 123.5 TFLOPS FP16 with sparsity suffices.
Use Cases
The RTX 4090 variant supplies 24 GB memory and 165.2 TFLOPS FP16 dense that accommodate larger models than the 16 GB and 61.7 TFLOPS FP16 dense on the RTX 5070 Ti variant.
The RTX 4090 variant offers 1008 GB/s bandwidth and 660.6 TOPS INT8 dense that sustain higher throughput than the 672 GB/s and 246.9 TOPS INT8 dense of the RTX 5070 Ti variant.
The RTX 4090 variant provides 24 GB capacity and 82.6 TFLOPS FP32 that handle extended fine tuning sessions beyond the limits of the RTX 5070 Ti variant.
Both variants deliver sufficient FP16 dense performance for image generation workloads when memory fits within 16 GB or 24 GB.
The RTX 4090 variant supplies 82.6 TFLOPS FP32 and 1008 GB/s bandwidth that accelerate compute heavy simulations more effectively than the RTX 5070 Ti variant.
