Alder Lake appears to be one of the first x86 hybrid processors to also support the PCIe 5.0 interface.

Intel is just beginning to support the PCIe 4.0 connection interface in its future Intel Core processors, and it is already beginning to talk about Alder Lake, which is the 12th generation of Core processors.

Alder Lake would use the 10nm SuperFin process node and it is going to make a big difference from the previous processors that Intel has brought to the desktop PC market. They are considered the first x86 hybrid processors because it will use an internal design similar to ARM chips, combining large and small cores. The large cores will use the Golden Cove and the small cores will be the Gracemont, which are usually low consumption.

Alder Lake’s innovations don’t end there and there is talk that it will be the first generation Core to welcome the PCIe 5.0 connection. The PCIe 5.0 standard promises to double the bandwidth speed of PCIe 4.0. The processor in question is said to have one 5.0 8-lane PCIe or two 4.0 4-lane PCIe.

The source refers to PCIe 5.0 tied to a CPU called Alder Lake-P. Note that there is no reference to an Alder Lake-S, which would traditionally be for desktop processors. The letter ‘P’ in Alder Lake-P is a mystery, it could be a new denomination for the next desktop chips, although it is also speculated that it could be next Atom P.

Previously, it was discussed that Alder Lake-P could host up to 14 cores, six Golden Cove cores and eight Gracemont cores.

For now, Rocket Lake-S processors will support PCIe 4.0 when they go on sale in early 2021. We’ll keep you posted.
