Ans: Yes, PCIe and PCIe are backward and forward-compatible This means that devices and components designed for PCIe can work in PCIe slots,

At 4K, the margins of difference grow even smaller For KitGuru, we will continue to use our i9-10900K test system for our reviews in the It should be backward compatible, but you will see less performance than if you had it in a PCIe slot since it runs at PCIe x8 instead
