Intel’s 500 series chipsets, including Z590 and B560, are set to be compatible with both 10th generation Comet Lake and 11th Generation Rocket Lake processors. The only platform that enables PCIe 4.0 will be a Rocket Lake processor at least at an i5 level, coupled with a Z590 or B560 motherboard. Alongside a full PCIe 4.0 x16 slot for graphics, one of the main benefits from PCIe 4.0, regardless of the 500-series motherboard model, is going to be had through storage. B560 will enable one PCIe 4.0 x4 M.2 slot from the CPU, with additional slots being PCIe 3.0 from the chipset. This sounds very identical to Z590, however the devil is in the details and our table below.
