Performance Analysis
The RTX 5080 vastly outpaces the RTX 2080 in compute performance: 56.3 TFLOPS versus 10.1 TFLOPS in both FP16 and FP32 represents a 5.6 times increase. This delta translates to faster machine learning training and inference, where FP16 handles mixed-precision computations efficiently and FP32 ensures single-precision accuracy for scientific simulations.
Memory specifications further favor the RTX 5080. Its 16 GB GDDR7 exceeds the RTX 2080's 8 to 11 GB GDDR6, enabling larger models without swapping. The 960 GB/s bandwidth compared to 616 GB/s supports bigger batch sizes in training, reducing per-iteration time and improving throughput in data-heavy inference pipelines.
Power draw reflects these gains: the RTX 5080's 360W TDP demands more cooling and electricity than the 215W RTX 2080, impacting cloud costs for prolonged runs. Overall, the newer architecture excels in modern AI pipelines requiring high throughput and capacity.
