What AI models can the NVIDIA GeForce RTX 5080 16 GB run?
At 4-bit quantization with an 8K-token conversation, 28 of the 146 open-weight models in our directory fit entirely in the NVIDIA GeForce RTX 5080 16 GB's 16 GB of video memory (about 15 GB usable), up to Safety GPT OSS 20B. With 32 GB of dual-channel DDR5-5600, 33 more run partly from system RAM, more slowly. Among models of 7B parameters or more, GPT OSS 20B is the fastest, at an estimated 209 to 271 tokens per second.

Frequently asked questions
What is the largest AI model the NVIDIA GeForce RTX 5080 16 GB can run?
At 4-bit quantization with an 8K-token conversation, the largest model in our directory that fits entirely in its 16 GB of video memory is Safety GPT OSS 20B (14 GB). With 32 GB of dual-channel DDR5-5600 for the overflow, larger models such as Skyfall 36B V2 also run, more slowly, partly from system RAM.
Can the NVIDIA GeForce RTX 5080 16 GB run GPT OSS 20B?
Yes. At 4-bit, GPT OSS 20B needs about 14 GB and fits entirely in the NVIDIA GeForce RTX 5080 16 GB's memory at an estimated 209 to 271 tokens per second.
Can the NVIDIA GeForce RTX 5080 16 GB run Qwen3 32B?
Partly. Qwen3 32B needs about 23 GB at 4-bit, so about 7.4 GB runs from system RAM (assuming 32 GB of dual-channel DDR5-5600) at an estimated 3.8 to 5.3 tokens per second.
Can the NVIDIA GeForce RTX 5080 16 GB run OpenAI GPT 120B?
No. OpenAI GPT 120B needs about 72 GB at 4-bit, more than the NVIDIA GeForce RTX 5080 16 GB can hold even with 32 GB of dual-channel DDR5-5600 for overflow.
These are estimates, not measurements: memory from each model's parameter count and published architecture, speed from memory bandwidth, calibrated on the AIPCs test bench. Drivers, software and prompt length move real results. How the estimate works.
