Local AI on the RTX 3090
With 24GB of VRAM, here's what this card can run and how fast — estimated from memory bandwidth, the number that actually decides LLM speed.
| Model | Best quant that fits | Est. speed | Verdict |
|---|---|---|---|
| Qwen3 30B-A3B | Q5_K_M | ~119 tok/s (Instant-feeling) | Runs great |
| Qwen3-Coder 30B-A3B | Q5_K_M | ~119 tok/s (Instant-feeling) | Runs great |
| Qwen3.6 27B | Q5_K_M | ~24 tok/s (Comfortable) | Runs great |
| Gemma 4 26B-A4B | Q5_K_M | ~99 tok/s (Instant-feeling) | Runs great |
| Mistral Small 3.2 24B | Q5_K_M | ~27 tok/s (Fast) | Runs great |

Browse all terms →Running AI Locally
Running large language models and AI on your own hardware instead of cloud services. Performance depends on VRAM, RAM bandwidth, and quantization — not CPU speed.
GPU (Graphics Processing Unit)
A specialized processor designed for parallel computation, primarily used for rendering graphics but increasingly important for AI and compute workloads.
VRAM (Video RAM)
Dedicated memory on a graphics card used to store textures, frame buffers, and render data. More VRAM allows higher resolutions and more detailed textures.
Ray Tracing
A rendering technique that simulates how light physically behaves — bouncing, reflecting, and refracting — to produce photorealistic lighting, shadows, and reflections in games.
DLSS (Deep Learning Super Sampling)
NVIDIA's AI-powered upscaling technology that renders games at lower resolution and uses neural networks to reconstruct near-native image quality at much higher frame rates.
FSR (FidelityFX Super Resolution)
AMD's upscaling technology that boosts frame rates by rendering at lower resolution and reconstructing detail. FSR 4 uses AI on RDNA 4 hardware; older versions work on any GPU.
