On the old machines, graphics were done by writing to memory addresses, I'm not sure if that is possible to do that anymore in Windows. Machine language was great at that.
That's a system architecture thing rather than a CPU thing. Yes, with the ZX Spectrum for example, there was no graphics accelerator or graphics memory, you just wrote to a particular block of main memory with the CPU, and the video DAC read out that same block of memory to generate the display. You could build a system like that with a modern processor if you really wanted to, or conversely you could make a Z80 system with a graphics accelerator - probably somebody did. But yeah, the simplicity of those systems was great for learning, you could really understand what you were doing end-to-end, without dealing with a whole bunch of frameworks and APIs and abstraction layers.
