What is the difference between a 7.5 inch skateboard and a 7.75 inch skateboard?
a 7.5 inch board is less wide and is made for street skating because you can flip it better
The socket 775 and the LGA 775 are the same. If you want to get technical it's not really a socket CPU, as the pins themselves are located on the socket grid and the back of the processor is flat with contact points. Totally opposite of what were used to seeing. Intel designed it this way to take increase the power distribution. The term LGA stands for Land Grid Array
