Performance Analysis
The RTX 5080 outperforms the RTX 3070 Ti by 2.8 times in FP16 and FP32 compute at 56.3 TFLOPS versus 20.3 TFLOPS. This delta translates to faster model training and inference: training a large language model completes in roughly one-third the time on the RTX 5080, assuming memory limits allow. Inference latency drops similarly for batch processing, enabling higher throughput in production deployments. Memory bandwidth of 960 GB/s on the RTX 5080 versus 448 GB/s supports larger batch sizes without bottlenecks: users process datasets twice as voluminous before saturation. The 16 GB VRAM on RTX 5080 handles models exceeding 8 GB, preventing out-of-memory errors common on RTX 3070 Ti during fine-tuning or Stable Diffusion generation. Higher TDP of 360 W on RTX 5080 reflects its power demands, but cloud providers manage cooling efficiently.
