Update: Some writers are speculating that the M1 chip has up to 16GB of onboard DRAM, probably thanks to a confusing slide in the Apple announcement.

Since the 13-inch MacBook Pro and the Mini have fans, I doubt the 16GB limit is thermal.

I'll expect the future 16-inch Mac Pro to have a more powerful chip - M2? - and support 64GB or more memory, with or without a discrete GPU. So the performance is improved over discrete GPUs, but the shared memory may throttle some graphically intense applications. Graphics resources, such as textures, images and geometry data, can be shared between the CPU and GPU efficiently, with no overhead, as there's no need to copy data across a PCIe bus.

means that the GPU and CPU are working over the same memory. What is Unified Memory? According to Apple: What's more, the touted Unified Memory Architecture just means that 16GB is shared between the CPU and graphics.
