Performance Analysis
FP16 and FP32 performance remains tightly matched between these GPUs: the RTX 3080 achieves 29.8 TFLOPS in both metrics, while the RTX 4070 Ti SUPER delivers 29.1 TFLOPS, a difference of under 3 percent. This equivalence implies comparable speeds for deep learning training and inference on models like transformers, where tensor core throughput dominates. Memory bandwidth reveals a substantial gap: 760 GB/s on the RTX 3080 surpasses 504 GB/s on the RTX 4070 Ti SUPER by 51 percent, enabling larger batch sizes in training and faster data movement for memory-bound inference. VRAM capacities align closely at 10 to 12 GB versus 12 GB, sufficient for most mid-scale models. Power draw varies significantly, with the RTX 3080's 320W TDP exceeding the RTX 4070 Ti SUPER's 200W by 60 percent; this favors Ada Lovelace for efficiency in sustained workloads, potentially halving energy costs per TFLOP.
