How to Choose an AI PC
The right AI PC is balanced around your models and datasets — GPU first, then memory, CPU and storage. Use the guide below to choose.
AI workloads run on the GPU, and VRAM decides how large a model you can load locally. More VRAM means bigger models and batch sizes — prioritise it for machine learning and local LLMs.
Generous RAM speeds data loading and preprocessing and lets you work with larger datasets. 32GB is a sensible base for serious work; step up to 64GB+ for heavy training and multitasking.
A strong multi-core CPU accelerates data preparation, feature engineering and the parts of the pipeline that aren't on the GPU. Pair a capable CPU with the GPU so it isn't the bottleneck.
Large datasets and model files benefit from fast NVMe SSDs, which cut load times and keep training pipelines fed. Add high-capacity storage for datasets you keep on hand.
High-end GPUs need a quality PSU with headroom and good cooling for sustained loads. If you plan to run local LLMs, size the GPU VRAM to the models you want — larger models need more.
