Best GPU for Llama 4 Scout (109B MoE) in 2026 Ranked
Meta's Llama 4 Scout, a 109 billion parameter mixture-of-experts model, requires approximately 25GB of VRAM for usable performance at Q4_K_M quantization. The RTX 5090 with 32GB of VRAM is presented as the sole single consumer GPU capable of running the model locally. For a more cost-effective local solution, a dual RTX 3090 setup offers comparable performance and more VRAM for a similar price, though it involves greater complexity. Cloud GPU instances are recommended for users who only need to run the model occasionally. AI
