Instance Property

maxTransferRate

The highest theoretical rate of transfer between system RAM and dedicated GPU memory (VRAM), measured in bytes per second.

Required.

Declaration

var maxTransferRate: UInt64 { get }

Discussion

The returned value indicates the theoretical maximum data rate in bytes/second from host memory to the GPU's dedicated memory. This is derived from the raw data clock rate and as such may not be reachable under real-world conditions. For built-in GPUs this value is 0.
