> The reason AI users like it is because it provides a large amount of higher-bandwidth memory at a price much lower than an equivalent GPU.

But unified memory isn't providing high bandwidth. Apple's specific implementation on pro or higher chips does. There's a zillion desktops and laptops running unified memory at low to medium-low speeds, and the baseline M series is part of that with its 128 bit bus.

Most unified memory devices are handicapped because of the unification, not boosted. Yet people keep praising unified memory.
