How Much Context Can a 128GB Mini PC Actually Hold? The KV Cache Math Nobody Runs Before Buying
Everyone sizes a unified-memory box against model weights. Almost nobody sizes it against the KV cache — and on a 128K-token agent run, the cache is the number that decides whether the job finishes. Here's the math, box by box, plus the KV-quantization trade that makes long first prompts slower, not faster.
192GB vs 128GB Unified Memory: What the Extra 64GB Actually Buys You
IFA 2026 filled the feeds with 192GB Gorgon Halo mini PCs. Capacity went up 50%; bandwidth went up about 7%. That asymmetry decides the whole purchase — here is the model-by-model list of what only 192GB runs, and why most buyers should still buy 128GB today.
How Much Unified Memory Do You Actually Need for Local AI? (64GB vs 96GB vs 128GB, 2026)
Unified memory on these boxes is soldered — it is the one spec you cannot change after checkout. Here is what each capacity tier actually runs, what the 64GB tier costs you in usable GPU memory, and why the extra 64GB buys context rather than a bigger model.
