Why have different CPU socket types?

[Technochicken]

What is the point. Is there some performance difference between say sockets 775 and 771, or any other socket type?

Yes there is in almost any socket type a major difference. now as far as 775 and 771 go it is probably less but if u look at the difference in the boards u see the 771 is for servers and some run 2 processors, and all are lot more expensive.

There are different sockets because of improvements in socket design. For example, compared to the older Socket 478, the almost-commonplace LGA 775 socket allows for better heat dissipation with the inclusion of a lid-like plate, which ensures that the processor is completely level and makes complete contact with the HSF on top, while also keeping the CPU fixed in place and not covering all of the CPU's surface. Also, the HDI is connected onto the mobo so as to provide better heat dissipation.

As for performance difference, no, Socket 771 borrows a large number of its designs from Socket 775, except for a few minor variations and the fact that 771 was designed for boards with multiple CPU sockets.

Your question can be compared to why are there different types of car engines. Each has different capabilities and designs plus advances in performance and technology.

Wouldn't the CPU be the engine? Maybe the socket is the transmission
