What does “unified memory” actually mean? Isn’t all modern memory unified between the CPU and iGPU?

Most video cards on say PCs are not unified memory, on Mx Macs, they do use unified memory.

As you said, there have been other unified memory systems on and off. It has pros and cons in many different ways.

It was explained to me as essentially there is an on die coprocessor doing the work of swapping and compressing in the background. Also it is faster since it is also on die.

The same thing that happens in x86 osx but now is hardware accelerated.
