The Dell OptiPlex 7070 SFF runs 9th Gen with backward BIOS compatibility for 8th Gen

The OptiPlex 7070 SFF uses LGA 1151 and primarily supports 9th Gen Intel Core i3, i5, i7, and i9 processors — including the i9-9900. A BIOS update also makes 8th Gen CPUs work, which is useful if you’re sourcing a cheaper used chip. With a 65W TDP ceiling, it handles high-end Coffee Lake Refresh chips without issue. The i9 support is rare in SFF business desktops and gives this OptiPlex unusual top-end reach.
