Performance Analysis
Raw compute shows minimal variance: the RTX 3080 Ti delivers 29.8 TFLOPS across FP16 and FP32, closely matched by the RTX 4070 Ti SUPER at 29.1 TFLOPS. This equivalence implies similar training and inference speeds for models where FLOPS determine bottlenecks. Memory bandwidth presents the key divergence: 760 GB/s on the RTX 3080 Ti versus 504 GB/s on the RTX 4070 Ti SUPER enables larger batch sizes and faster data movement in training large language models. Lower bandwidth on the RTX 4070 Ti SUPER may constrain high-throughput inference with extensive datasets. Power draw affects scalability: the 200 W TDP of the RTX 4070 Ti SUPER contrasts with 320 W on the RTX 3080 Ti, allowing more instances per server and reduced operational costs in prolonged cloud sessions.
