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.
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.

Best for: Voice assistants, vision plus small language models, and learning CUDA at low power.
For projects and tinkering; for a home chat server a used GPU or a Mac mini is better.
