[ GLOSSARY DEFINITION ]
Memory
Memory Bandwidth
How much data memory can move per second (GB/s); crucial for GPU and SoC performance.
Also known as:
Bandwidth
Max Bandwidth
Full Definition & Technical Explanation
Memory bandwidth is the data-transfer rate between memory and the chip, e.g., Max bandwidth: 75.8 Gb/s on SoCs or Memory Bandwidth: 102.4 GB/s on GPUs. It depends on bus width, memory type, and clock.
Low bandwidth bottlenecks gaming and AI. GDDR7, LPDDR5X, and unified memory all target higher bandwidth.
Related Technical Terms
GDDR7
Graphics DRAM generations for GPUs; GDDR7 is the newest, with the highest bandwidth.
Memory
LPDDR5
Low-power DDR memory generations; LPDDR5X is faster (up to ~8533 MT/s) and more efficient.
Memory
Unified Memory
A memory pool shared by CPU and GPU (Apple silicon); fast and efficient but fixed and un-upgradable.
Memory
VRAM
Dedicated memory on a graphics card; more VRAM enables higher resolutions and textures.
