Performance Analysis
The FP16 dense performance reaches 58.3 TFLOPS on the RTX 4070 and 209.5 TFLOPS on the RTX 5090. This difference means the RTX 5090 delivers 3.59 times the dense FP16 throughput for training and inference tasks. The FP16 with sparsity performance reaches 116.6 TFLOPS on the RTX 4070 and 419 TFLOPS on the RTX 5090 which maintains the same ratio for sparsity enabled workloads. Memory bandwidth of 504 GB/s on the RTX 4070 versus 1792 GB/s on the RTX 5090 allows larger batch sizes on the RTX 5090. The FP32 performance of 29.1 TFLOPS on the RTX 4070 versus 104.8 TFLOPS on the RTX 5090 further widens the gap for precision sensitive computations. The TDP of 200W on the RTX 4070 versus 575W on the RTX 5090 indicates higher power draw accompanies the performance gains.

When to Choose the RTX 4070
The RTX 4070 suits environments with strict power limits due to its 200W TDP. Systems that require only 12-16 GB VRAM and 504 GB/s bandwidth benefit from this GPU without excess capacity.
When to Choose the RTX 5090
The RTX 5090 suits workloads that require 32 GB VRAM and 1792 GB/s bandwidth. Tasks that scale with 209.5 TFLOPS dense FP16 or 104.8 TFLOPS FP32 gain from this GPU.
Use Cases
The RTX 5090 provides 32 GB VRAM and 209.5 TFLOPS dense FP16 which exceed the RTX 4070 limits for large model training.
The RTX 5090 achieves 419 TFLOPS FP8 dense which supports faster inference than the 116.6 TFLOPS FP8 dense on the RTX 4070.
The RTX 5090 memory bandwidth of 1792 GB/s enables larger batch sizes during fine-tuning compared to 504 GB/s on the RTX 4070.
Both GPUs handle Stable Diffusion though the RTX 5090 FP16 dense figure of 209.5 TFLOPS offers speed advantages while the RTX 4070 suffices for smaller workloads.
The RTX 5090 FP32 performance of 104.8 TFLOPS supports intensive scientific calculations beyond the 29.1 TFLOPS of the RTX 4070.
