Performance Analysis
The RTX 3080 provides 29.8 TFLOPS FP32 compared to 8.9 TFLOPS FP32 on the GTX 1080. This FP32 difference translates to higher throughput for training and inference tasks that rely on single precision operations. The RTX 3080 also lists 59.5 TFLOPS dense FP16 which doubles its FP32 rating and supports accelerated mixed precision workloads. Memory bandwidth of 760 GB/s on the RTX 3080 versus 320 GB/s on the GTX 1080 allows larger batch sizes during model execution. The GTX 1080 lacks published dense FP16 figures so direct dense FP16 comparisons remain limited to the RTX 3080 specifications alone.

When to Choose the GTX 1080
The GTX 1080 suits environments where power limits constrain operations to 180W TDP. Its 8.9 TFLOPS FP32 and 320 GB/s bandwidth meet requirements for lighter inference or scientific computing jobs that do not demand higher throughput. Users select the GTX 1080 when PCIe 3.0 interconnect and lower VRAM needs align with existing hardware constraints.
When to Choose the RTX 3080
Its dense FP16 rating of 59.5 TFLOPS enables faster training and inference compared to FP32 only devices. Selection occurs when 320W TDP tolerance and PCIe 4.0 support match the demands of larger batch processing or sparsity accelerated tasks.
Use Cases
The RTX 3080 supplies 29.8 TFLOPS FP32 and 59.5 TFLOPS dense FP16 which exceed GTX 1080 capabilities for sustained training runs.
Higher memory bandwidth of 760 GB/s on the RTX 3080 permits larger batch sizes than the 320 GB/s on the GTX 1080 during inference.
The RTX 3080 dense FP16 figure of 59.5 TFLOPS accelerates fine tuning steps beyond the GTX 1080 FP32 limit of 8.9 TFLOPS.
The RTX 3080 provides 238 TOPS dense INT8 which supports efficient image generation workloads unavailable on the GTX 1080.
