Performance Analysis
The RTX 4070 Ti SUPER holds a compute advantage: its 44.1 TFLOPS in FP16 and FP32 exceeds the RTX 3090's 35.6 TFLOPS by 24 percent. This delta benefits inference tasks with high throughput demands and training where raw FLOPS accelerate iterations. However, the RTX 3090's 24 GB VRAM surpasses the 16 GB on the RTX 4070 Ti SUPER, enabling larger batch sizes in memory-constrained LLM training.
Memory bandwidth reveals another gap: the RTX 3090's 936 GB/s outpaces the RTX 4070 Ti SUPER's 672 GB/s by 39 percent. Higher bandwidth supports faster data transfers, crucial for large batch sizes in fine-tuning or Stable Diffusion where datasets exceed 12 GB limits. The RTX 4070 Ti SUPER's lower 285 W TDP versus 350 W reduces power costs in prolonged cloud sessions, leveraging Ada Lovelace efficiency.
