Performance Analysis
The dense FP16 performance of 59.5 TFLOPS on the RTX 3080 exceeds the dense FP16 performance of 40.3 TFLOPS on the RTX 2080 while FP32 figures show the same ordering at 29.8 TFLOPS versus 10 TFLOPS. This delta indicates the RTX 3080 supports larger batch sizes during training and inference workloads that rely on dense FP16 or FP32 operations. Memory bandwidth of 760 GB/s on the RTX 3080 versus 448 GB/s on the RTX 2080 further enables increased batch sizes in memory bound scenarios. Dense INT8 performance stands at 238 TOPS on the RTX 3080 against 161.1 TOPS on the RTX 2080 with sparsity figures available only for the RTX 3080 at 476 TOPS.

When to Choose the RTX 2080
The RTX 2080 suits scenarios where power draw must remain at 215W TDP and where NVLink interconnect is required for multi GPU setups. Its 448 GB/s bandwidth and 8 to 11 GB GDDR6 VRAM suffice for lighter inference tasks that do not demand the higher dense FP16 throughput of 59.5 TFLOPS.
When to Choose the RTX 3080
Its PCIe 4.0 interconnect and 10 to 12 GB GDDR6X VRAM support modern dense FP16 operations at 59.5 TFLOPS with a TDP of 320W.
Use Cases
The RTX 3080 delivers 59.5 TFLOPS dense FP16 compared to 40.3 TFLOPS on the RTX 2080 allowing larger training batches.
Dense FP16 at 59.5 TFLOPS and 760 GB/s bandwidth on the RTX 3080 exceed the RTX 2080 values for faster inference throughput.
Higher dense FP32 at 29.8 TFLOPS and memory bandwidth of 760 GB/s on the RTX 3080 support efficient fine tuning compared to 10 TFLOPS and 448 GB/s.
The RTX 3080 provides 59.5 TFLOPS dense FP16 versus 40.3 TFLOPS enabling quicker image generation workloads.
