oh, i guess my question may still not be clear, are the pins on the chipsets the same, and if not, what are my options for something that will fit
What you intend to do will not work at all.
You obviously are mixing the chipset of a mainboard with the CPU integrated graphics adapter (iGPU). You cannot change the chipset of a system by just replacing the CPU. Furthermore the CPU socket of your old Dell Vostro 1520 is not compatible with a Haswell CPU, which needs a Socket 1150.
