You don't get it.
Person wants a computer. Person goes to shop, buys computer.
Intel knows people want computers, Intel make CPUs.
AMD knows people want computers, AMD make better CPU, everybody buys AMD computers from shops because it's got "better", "faster" all over the box.
Intel sees this and makes CPUs better than AMD.
Cycle repeat.
Just for one second realise that only a VERY small percentage of computer users are enthusiasts, and you'd realise that a very basic computer is more than enough for most users.
People buy the computers and laptops that have the higher numbers on them. They think it's better (it probably is) but they have NO CLUE as to why, nor do they care why.
It's a business practice that Intel are doing, continually killing of the older processors so that all the Intel computers constantly have "faster", "better", on the box. That's it.
