I have a Dell Inc Motherboard, Model: 0K3CM7 A00 Chipset: Intel Rocket Lake----Southbridge: Intel H470 I understand that my current Intel core i5 11400 is compatible with socket 1200 LGA and I know that I would like to upgrade to a i7-11700 which is also compatible with socket 1200 LGA but I am unsure of the chipset and whether an upgrade of my BIOS will be necessary. If anyone could be of help explaining this it would be much appreciated, I am unable to find this Motherboard anywhere for a compatibility check on Dell websites. It would be nice to know what options I have for CPU upgrades.  
XPS 8940, what CPU is compatible?
