LOCAL LLM Compatibility Evaluation

This quick guide shows what types of large language models (LLMs) each of these laptops could support, based on their respective hardware specifications. It's meant to help you compare their suitability for running AI models locally.

LLM Category	Gigabyte A18	Dell Alienware X16
Small Models(1-3B):Examples: Phi-2, Qwen-1.8B	✔ Run smoothly.	✔ Run smoothly.
Medium Models(7-8B):Examples: Mistral-7B, Qwen-7B	✔ Good performance.	✖ Not supported.
Large Models(13-30B):Examples: Mixtral, Qwen-14B	⚠ Can run using CPU + RAM fallback. Expect slower performance.	✖ Not supported.
Extra-Large Models(65B+):Examples: LLaMA2-70B, Qwen1.5-72B	⚠ Possible with CPU + RAM fallback using quantized models.	✖ Not supported on most systems. Requires high-end GPU or advanced setup.

Note: Optimized (e.g., 4-bit) models may run on limited hardware. Performance depends on runtime and setup.

📌 MoE Models: Some models like Mixtral 8x7B and Qwen3-30B-A3B use a Mixture of Experts (MoE) design, activating only part of the model during inference. This means they can often run efficiently on laptops with 12–16 GB of VRAM when quantized.
