No.
We use dGPU to mean a card, typically non-unified memory, on PCIe. By contrast, the M1 has an iGPU, meaning integrated rather than dedicated. Most iGPUs rely on unified memory since they are on the same package as the CPU(s). Most or all Intel processors these days (e.g., Alder Lake) have some sort of integrated GPU on the package, in order to allow some customers to skip installing a graphics card in their product – the models likely to go into notebooks tend to have larger iGPU arrays than the workstation-class processors.
