Performance Analysis
The RTX 3070 Ti demonstrates superior compute capability: its 20.3 TFLOPS in FP16 and FP32 doubles the RTX 2080 Ti's 10.1 TFLOPS. This delta accelerates deep learning training by enabling faster matrix multiplications and model optimizations. For LLM inference, higher TFLOPS reduces latency in token generation, making the RTX 3070 Ti preferable for high-throughput serving.
Memory bandwidth reveals a key tradeoff: the RTX 2080 Ti's 616 GB/s exceeds the RTX 3070 Ti's 448 GB/s. Higher bandwidth sustains larger batch sizes in training without stalling data transfers, benefiting memory-bound workloads like large-model fine-tuning. The RTX 2080 Ti's up to 11 GB VRAM versus 8 GB further supports bigger models or datasets.
Power draw remains close at 215 W for RTX 2080 Ti and 220 W for RTX 3070 Ti. Ampere's architectural improvements enhance tensor core efficiency over Turing, amplifying real-world gains in mixed-precision tasks beyond raw specs.
