Local AI hardware FAQ

People also ask
How much VRAM do I need to run modern local language models?
It depends on model size and quantization. Many 7B models can run around 8GB VRAM, 13B models are typically more comfortable at 12GB to 16GB, and 70B-class models generally need either high VRAM cards or multi-GPU/system memory strategies.
Should I prioritize VRAM or raw speed when choosing a GPU for AI?
For most local AI users, VRAM is the first constraint because it determines what model sizes and context lengths fit. After fit is solved, throughput and efficiency differences become the key decision factors.
Can I run local AI on a Mac mini or do I need a desktop GPU?
You can run local AI on Apple Silicon systems, especially for smaller and mid-sized models. Dedicated desktop GPUs usually offer higher peak throughput and easier scaling for larger model workloads.
Where should I start if I am new to local AI hardware?
Start with compatibility checks for the models you want, review a few benchmark comparisons in your budget range, then pick either a prebuilt system page or a full DIY build guide to execute.
