UnverifiedUnified memory's peak bandwidth is still lower than the VRAM bandwidth of high-end discrete graphics cards, and its capacity ceiling is locked by the machine's configuration and cannot be upgraded after purchase.70% similarUnverifiedApple Silicon's unified memory architecture can reduce latency and power consumption for small and medium model inference on the basis of single-machine sharing, but once extended to a distributed environment, cross-device communication still has to go over the network, and the bandwidth dividend of unified memory cannot be passed through directly.69% similar
