You're looking at a very high level picture of the CPU. The different coloured sections represent the different logical segments of the CPU. I can't tell you specifically what each section is and maybe someone more informed could clear that up but among there will be: registers (memory), alu (math), CU (control, brain), buses (transport), the GPU, and some other miscellaneous sections (IR,PC,etc..). For the holes, I don't know what they mean I have never seen those on a cpu die.
