APU is a term AMD made up to describe their new line of Cpu + Gpu models. The are not a term that describes how Intel CPUs are modeled.
How Intel "models" their CPUs is irrelevant.
While AMD popularized the use of term APU (they did not invent it or make it up), the "Accelerated Processing Unit" actually refers to any CPU bundled with any additional processing resources integrated in it and is in no way limited to AMD's own products.
It does not matter whether or not Intel markets their CPUs as APUs, most Intel's CPUs still meet the generic definition.
