What it can run

Estimate

Popular models at Q4_K_M with a 32K-token context. Memory needed from real model files; speed is the theoretical ceiling.

Theoretical maximum for generating text: memory bandwidth divided by the bytes read per token. Real runs usually reach about half to three quarters of it.

Where to buy

Prices are editorial references (launch price and a typical street price on the date shown), not live prices. In 2026 the memory shortage has pushed many prices well above launch.

Overview

Editorial opinion

Best for: Voice assistants, vision plus small language models, and learning CUDA at low power.

Editorial opinionWould we buy it today?

For projects and tinkering; for a home chat server a used GPU or a Mac mini is better.
