Why does intel change sockets so often?

The best reason to say why Intel changes sockets so often is because they rolled most of the chipset's functions into the CPU starting with LGA1156. This means that if they want to change their platform to any significant degree, they have to change sockets in order to accommodate the necessary I/O coming from the CPU.

Intel sockets used to just supply power and the FSB to the CPU. Unless they needed more power or significantly changed the FSB, they didn't need to change the socket. That's why LGA775 stayed around so long- they didn't change the bus nor did they change the amount of power the chips used. AMD is much the same way- their non-APU sockets supply I/O lines to memory and a HyperTransport link or links to the chipset/other...
No it is the changed in the technology and how the chips are made. For example not too long ago you only got a SINGLE CPU Core on the chip. Before that the fabricating of the CPU was as big as the palm of your hand (now it fits on the tip of your finger). Also demand changes occurred, before Vista came out the focus was on desktop boxes, not laptops, which need power via battery, different design for airflow due to limited space, etc. Lastly the actual materials changed, we used silicon before now they are moving to newer materials and even nano-tech to make the connection at smaller levels that silicon couldn't possible do.
 
Because Intel's Tick-Tock strategy is to change everything up about every other year so they can wring more money out of people who upgrade every other year.

It's always about money...especially with Intel if it was up to Intel, we'd all still be running single core Pentiums sub 1.0 GHz and paying $1000 per chip for it...

Thank heaven AMD is around to keep their pricing...well...not honest...but less gouging. I swore of paying any more money that goes to anything to do with Intel a long time ago. If they can rook you out of money somehow or another...they will.

The sad thing is...consumers gladly take this abuse and keep paying them money!

AMD is much the same way- their non-APU sockets supply I/O lines to memory and a HyperTransport link or links to the chipset/other sockets. Unless you change the memory interface, they didn't make a new socket. That's why AMD stuck with AM2/AM2+ through the whole DDR2 generation and AM3/AM3+ through the whole DDR3 generation. AMD's APU sockets have a lot more of the chipset functions on the CPU and this is why they go through FM sockets approximately the same pace Intel goes through LGA115x sockets.

The only 2 AMD chips that offer better price/performance than Intel are the A10-6800k and FX 6300.
 


And the A10-5800k( vs. i3), and the FX 6350(same money as i3), and the FX 8320(same money as i3), and the FX 8350 (less money than any i5), and the FX 4350 (compares to i3 moneywise)
