But people eventally see through the veil and they get angry.
LOL, no. Maybe a few entitled enthusiasts on tech boards who really are never happy with anything that any company gives them will complain (they always complain), but you really have to understand that the average Joe and business consumers (the two volume customers of mainstream-powered desktops) don't think like this.
Consumers and businesses by and large don't buy processors. They buy computers.
Consumers buy computers generally for the following reasons:
1. The one I have doesn't work well or it broke. I need a new one.
2. I, or the person for whom I am buying it, does not have a computer but wants/needs one.
Those people either go online (using old barely working computer or with their smartphone) and pick out a computer, or they go to Best Buy, Wal-Mart, Staples, or someplace like that and pick out a computer.
They don't know a thing about IPC, clock speed, or anything else. There is sometimes (often?) a helpful infographic in the computer section, almost certainly put there through some marketing agreement between the retailer and Intel, that explains in very simple terms what Celeron, Pentium, Core i3/i5/i7 are, and what you should buy based on your "use case" (these use cases are in very broad terms and would look silly to an enthusiast).
The potential buyer has a certain budget in mind, with perhaps a little bit of wiggle room. Then that person looks at the different computers within his or her price range, and either independently or with the help of a sales rep (who has just enough knowledge to explain in broad terms what the different features/options mean) picks a system that she or he thinks will meet their needs for a while.
That person walks out the door with her or his computer, and probably won't be back to buy another computer for a long time.
If you really want to understand how most people buy computers, just go to the computer section in one of the stores I mentioned above, and ask a sales rep to help you pick out a computer. Tell him/her what you want to use it for, how much you're willing to spend, etc. and watch the process unfold.
