I have a Dell Latitude E5400 with an Intel Core 2 Duo T7250. I would like to upgrade the CPU. According to CPU-Z,my socket is Socket P (47 and the baseboard is 0D695C,manufactured by Dell,though I could not find much information on that online. The computer runs Windows 10. I'm looking at the Core 2 Duo P8700 as an upgrade option.

1)Is the P8700 compatible? If not,what is?
2)How do I determine if a CPU is compatible?
3)How do I compare 2 processors and tell which is better? What numbers should I be looking at?

By the way, I do know it won't make much difference. It doesn't cost much, so I want to do it anyway.

well first thing that jump to me are the following things that could be a game crasher for you even if it is the same socket type

1. Lithography, T7250 is 65nm vs P8700 is 45nm
2. Bus speed: T7250 is 800 mhz vs P8700 is 1066 Mhz

those things need to be addressed by the motherboard specification (which I could not find)

Thanks for your help.
Another thing I noticed was that the T7250 supports sockets PBGA479 and PPGA478 while P8700 supports sockets BGA479 and PGA478. Will that extra P make a difference?
