Do Macs Have Custom Models of Intel Processors? Do Apple Computers use the same-exact Intel processors available to PC builders or are they custom models made just for Apple? For example, if a Mac is marketed as having an Intel i7 3.3 GHz x-generation processor and there is a matching processor listed on Ark for that chipset "generation," is it safe to assume that same-exact processor is in the Mac? Or does Apple get custom models within the chipset families just for their computers?

Also, is there a website where I can see the processor model numbers available in Macs so I don't have to spend time trying to match Apple's marketing to Intel's specs?
They are identical. Don't know if we are allowed to talk about it, but all I can say is to search osx86project or tonymacx86, you will see the hardware.

If you search the Intel chips the Macs are using (eg. i7-4770HQ), you will see Windows laptops are using them as well.
