Yes to 10900kf, no to 11900kf per G5 5000 spec.

the kF cpu have 125W TDP, for which your current heatsink cannot handle. You need to upgrade cooler to a better air cooler or liquid cooling (AIO).

Table 1. Processors

Yea, I saw that link and understand about the heatsink. But is there a reason the 5000 can't take the 11900kf? Since it is the same socket?

It should since its optioned just fine with the XPS 8940!  Just why would you since all I ever hear is about how much better the 10th generation is over the 11th.

Also, you’re not going to get usage of the Gen 4 PCIe abilities because of the Dell motherboard.

Hello,

Were you able to upgrade to 11th Gen Intel CPU? I have the same PC with H470 chipset.
