Performance Analysis
The RTX 3090 surpasses the GTX 1070 Ti by a factor of four in FP16 and FP32 performance: 35.6 TFLOPS versus 8.9 TFLOPS enables faster model training and inference times. Training large language models benefits from this, as the Ampere GPU processes computations over four times quicker, reducing epochs from days to hours in typical deep learning pipelines. Memory differences prove critical for real-world applications: the RTX 3090's 24 GB VRAM and 936 GB/s bandwidth support batch sizes up to three times larger than the GTX 1070 Ti's 8 GB and 256 GB/s limit. This allows handling bigger models without out-of-memory errors during inference or fine-tuning. NVLink interconnect on RTX 3090 further accelerates multi-GPU setups, absent on the PCIe-only GTX 1070 Ti.
