Methodology Note

Performance estimates for the RTX 3080are based on InferenceBench's roofline performance model with CUDA kernel-level optimization including FlashAttention v2 and PagedAttention. Memory calculations account for model weights (10 GB GDDR6X available), KV-cache allocation, and activation memory. Throughput predictions use the RTX 3080's rated 760 GB/s memory bandwidth and 47 BF16 TFLOPS compute capacity as roofline ceilings, with empirical correction factors per GPU architecture (ampere). See our full methodology.

Frequently Asked Questions

How many AI models can run on RTX 3080?

The RTX 3080 can run 201 AI models from our database within a single node. Compatible models range across various parameter sizes depending on the quantization precision (BF16, FP8, INT4). Smaller models fit on a single GPU while larger models may require multi-GPU setups up to 4x RTX 3080.

What is the RTX 3080 inference throughput?

The RTX 3080 delivers 47 BF16 TFLOPS and 47 FP8 TFLOPS with 760 GB/s memory bandwidth. Actual inference throughput (tokens/sec) depends on the model size, precision, and batch size. Use our calculator for model-specific throughput estimates.

How much does RTX 3080 cost per hour?

The RTX 3080 is available starting from $0.14/hour via tensordock. Prices vary by provider and pricing tier (on-demand, reserved, spot). Compare pricing across all providers in the table above.
