Three steps to the right class

Not every “AI PC” is a good LLM PC

For local language models, the crucial question is whether model weights, context cache and runtime headroom fit into fast memory together. An impressive NPU TOPS figure alone does not answer it.

01

Choose model size

A quantized 8B model is modest. 32B and 70B models need considerably more memory but can cover more demanding tasks.

02

Speed or capacity?

A discrete high-end GPU delivers excellent speed. Large unified memory can hold bigger models, with a different performance profile.

03

Check the exact system

Cooling, memory allocation, storage, upgradeability and the exact GPU configuration matter as much as the processor name.

Quick orientation

Which memory tier fits?

Understand model memory
16 GB

Compact models

A practical starting point for 7B to 14B models in suitable quantization and normal context lengths.

Chat · summarization · first coding workflows
64–128 GB

Large models

The capacity class for 70B models and long contexts, depending on runtime and quantization.

70B · long context · agent stacks

These values are conservative guidance, not a guarantee. Architecture, quantization, context, KV cache and runtime all change memory use.

Current shortlist

Different routes to the same goal: maximum memory capacity in a small footprint or very high GPU performance in a desktop.

Your workload matters

From model to suitable PC in about a minute

The finder considers model class, context length, intended use and your main priority. It returns an explainable hardware class, not false precision.

Evidence over mystery

How we form our recommendations

Primary sources first

We prefer manufacturer and platform documentation for technical specifications.

Configurations, not names

One product name can cover different memory, storage and GPU variants. The linked configuration is what matters.

No invented hands-on tests

These pages provide buying guidance and editorial analysis. We only claim hands-on testing when it is documented.
