NVIDIA GeForce RTX 5080: common questions
- What models can the NVIDIA GeForce RTX 5080 run?
- With 16GB of VRAM it can run models up to roughly 23B parameters at a 4-bit quantisation, or smaller models with more context. Use the hardware matrix for specifics; these figures are approximate.
- How much power does the NVIDIA GeForce RTX 5080 draw?
- About 360W under load, so pair it with a power supply that has real headroom.
Strengths
- Fast GDDR7 memory and current-generation performance
- Runs 7B to 14B models very comfortably
- Lower power and heat than the 5090
Weaknesses
- 16GB is the main limit, ruling out larger models except at low quantisations
- Noticeably less memory than a used 3090 at a similar price point
- Long-context work eats into that 16GB quickly
