are the processors that are compatible with your motherboard. Might want to make sure your motherboard is on the latest BIOS version prior to any CPU upgrade. Going for anything beyond the 9th gen of Intel processors means that you're going to have to change the motherboard. If you didn't notice, the limitation in your choice of CPU's is the TDP, given how all the compatible processors are 65W in TDP.
