My understanding is that it has always been a CPU and GPU combined, but is some marketing wangle as you suggest. I've owned one in the past and it was generally quite fast in general use, I believe it off-loaded simple GPU related tasks to the GPU part of the APU which ultimately reduced the graphics latency. This seems to be quite similar to the Mali GPU which can be bundled on ARM packages to handle simple graphics [2]. I believe this is how something like the Raspberry Pi can output 4k over HDMI despite not being particularly powerful.
