It's not that simple though. It's cheaper to engineer one chip that does everything then selectively disable certain features for lower end SKUs. Going to the effort of making different hardware for the lower end SKUs that completely lacks these features would end up raising prices for consumers because it makes engineering and manufacturing more costly. The other alternative is they just don't offer lower price SKUs and make everyone buy top-end parts.
