Quick Answer

GPU memory bandwidth measures data transfer rate between processor core and dedicated VRAM. Bus width and memory clock frequency determine total throughput, typically expressed in gigabytes per second. High bandwidth prevents processing bottlenecks during high-resolution rendering and heavy compute tasks, though architecture and cache size also dictate overall system performance.

GPU memory bandwidth is the maximum rate at which a graphics processor can read data from and write data to its onboard video memory. It is expressed in gigabytes per second (GB/s) or terabytes per second (TB/s). It is a derived figure, not an independent hardware feature. It is the product of the memory interface width and the per-pin data rate of the memory devices. This guide covers how that figure is produced, how it limits real workloads, and how to interpret it on manufacturer specification sheets.

What Memory Bandwidth Measures

Memory bandwidth measures data throughput between the GPU die and the VRA
