Intel has no APU. APU is a registered trademark and patented product of AMD. Without AMD's permission, Intel can't label APU on any product, nor can it produce APU (even if Intel has this technology).

Intel's integrated CPU is called core graphics card, not APU (don't think they are just different names, in fact, APU's performance is much stronger than core graphics card). There are core graphics cards integrated in 36 12QM and 3520M, and the integrated models are the same, both of which are HD 4000.
