Performance Analysis
The FP32 performance ratio shows the RTX 4080 at 48.7 TFLOPS against the RTX 3060 at 12.7 TFLOPS. This gap affects both training and inference workloads where higher FP32 throughput permits larger models or faster iteration. Memory bandwidth of 717 GB/s on the RTX 4080 versus 360 GB/s on the RTX 3060 supports larger batch sizes during training without memory stalls. The RTX 4080 lists FP16 dense at 97.5 TFLOPS and FP16 with sparsity at 195 TFLOPS while the RTX 3060 lists no FP16 figures. Dense FP16 on the RTX 4080 exceeds its own dense FP32 of 48.7 TFLOPS by a factor of two.

When to Choose the RTX 3060
The RTX 3060 suits environments where power draw must stay near 170W TDP. Its 12.7 TFLOPS FP32 and 360 GB/s bandwidth fit smaller scale scientific computing tasks that do not require the 48.7 TFLOPS or 717 GB/s of the RTX 4080. Deployment in PCIe systems with limited cooling capacity favors the lower TDP option.
When to Choose the RTX 4080
Its 16 GB GDDR6X VRAM enables larger batch sizes than the 8 to 12 GB on the RTX 3060. Dense FP16 at 97.5 TFLOPS and dense INT8 at 389.9 TOPS accelerate inference and fine tuning relative to the RTX 3060.
Use Cases
The RTX 4080 provides 48.7 TFLOPS FP32 and 717 GB/s bandwidth that exceed the RTX 3060 values of 12.7 TFLOPS and 360 GB/s.
Dense FP16 at 97.5 TFLOPS on the RTX 4080 supports faster inference than the RTX 3060 which lists no FP16 figure.
The RTX 4080 lists dense INT8 at 389.9 TOPS and 16 GB VRAM while the RTX 3060 lists no INT8 figure and 8 to 12 GB VRAM.
Higher memory bandwidth of 717 GB/s on the RTX 4080 permits larger image batches than 360 GB/s on the RTX 3060.
The RTX 3060 at 170W TDP fits power constrained nodes while the RTX 4080 at 48.7 TFLOPS FP32 fits performance nodes.
