Methodology Note
Performance estimates for the RTX 5090are based on InferenceBench's roofline performance model with CUDA kernel-level optimization including FlashAttention v2 and PagedAttention. Memory calculations account for model weights (32 GB GDDR6X available), KV-cache allocation, and activation memory. Throughput predictions use the RTX 5090's rated 1792 GB/s memory bandwidth and 210 BF16 TFLOPS compute capacity as roofline ceilings, with empirical correction factors per GPU architecture (blackwell). See our full methodology.
Frequently Asked Questions
How many AI models can run on RTX 5090?
The RTX 5090 can run 246 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 5090.
What is the RTX 5090 inference throughput?
The RTX 5090 delivers 210 BF16 TFLOPS and 420 FP8 TFLOPS with 1792 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 5090 cost per hour?
The RTX 5090 is available starting from $0.89/hour via vast_ai. Prices vary by provider and pricing tier (on-demand, reserved, spot). Compare pricing across all providers in the table above.
