[ GLOSSARY DEFINITION ]
Memory
Unified Memory
A memory pool shared by CPU and GPU (Apple silicon); fast and efficient but fixed and un-upgradable.
Also known as:
Unified RAM
Unified memory architecture
Full Definition & Technical Explanation
Unified memory lets the CPU and GPU access one fast memory pool (Apple M-series, and increasingly Snapdragon X PCs). No copying between separate CPU/GPU RAM means better efficiency and bandwidth.
Downside: it is soldered, so you must choose capacity at purchase. Compare bandwidth, not just GB.
