For compatibility with Intel's 12th and 13th Gen Core CPUs, you'll need to use a motherboard with a Z790, H770, B760 Z690, H670, B660, or H610 chipset.

The W680 and Q670 chipsets are intended for workstation and business use cases; their availability in stand-alone motherboards is limited.

For 12th and 13th Gen Intel Core CPUs, PCIe 5.0 support means either one x16 or two x8 PCIe slots can run at PCIe 5.0 speeds for graphics or storage purposes. The CPUs provide four additional PCIe 4.0 lanes (e.g., an x4 slot) that you can only use for storage devices.

Note that the chipsets don't provide PCIe 5.0 lanes for M.2 storage devices. PCIe 5.0 is only available for the PCI-Express slots connected directly to the CPU. However, the chipsets do use a new DMI 4.0 link which is twice as fast as the 3.0 link used by the 500-series chipsets.

How Fast Is PCIe 5.0?

PCI-Express speeds are based on the PCI-Express version and the number of lanes used. One lane is referred to as x1, two lanes as x2, etc. PCI-Express technically supports up to a width of x32. However, most consumer motherboards have some set of these PCIe widths: x1, x2, x4, x8, x16.

Intel's 12th generation CPUs currently provide PCIe 5.0 support for CPU lanes (i.e., one x16 or two x8 PCIe slots) and PCIe 4.0/3.0 speeds for the remaining lanes.

The bandwidth for each PCIe 5.0 lane is 4 GB/s. 4 GB/s per lane means that if you use a PCI-Express 5.0 x16 device, it would have up to 64 GB/s of bandwidth available to it.

NVMe M.2 SSD cards use 2 or 4 lanes, which means they have 4–8 GB/s available to them with PCIe 4.0.

Samsung 980 1 TB M.2 SSD

NVMe PCIe add-in cards can use up to 16 lanes in an x16 slot, thus having up to 32 GB/s of bandwidth available to them with PCIe 4.0.

In comparison, PCIe 3.0 has half of the bandwidth of PCIe 4.0.

What Is the Latest Version of PCI-Express Available in CPUs?

The latest available version of PCI-Express is PCIe 5.0. PCIe 5.0 CPUs are available from Intel and AMD.

Intel's 12th and 13th generation Core CPUs currently provide PCIe 5.0 support for CPU lanes (i.e., one x16 or two x8 PCIe slots) and PCIe 4.0/3.0 speeds for the remaining lanes.

AMD's Zen 4-based Ryzen 7000 desktop CPUs are their first to support PCIe 5.0.

PCIe versions such as 3.0, 4.0, and 5.0 are sometimes informally referred to as PCIe Gen 3, PCIe Gen 4, and PCIe Gen 5. This naming is based on them being the third, fourth, and fifth generations of PCI-Express.

PCIe 5.0 graphics cards and storage devices are not currently on the market.
