Z590 Motherboards – PCIe 4.0 Compatible w/11th Gen CPUs Only

While perhaps not a surprise, by way of WCCFTech we’ve learned that multiple Z590 motherboards are noting that PCIe 4.0 support for GPUs and M.2 devices is limited to 11th Gen Rocket Lake-S CPUs. This will come with great disappointment for 10th Gen owners, limited to PCIe 3.0 lanes without upgrading their CPU.

As per the previously leaked information which covered all Intel Rocket Lake SKUs, the lineup will consist of Core i9, Core i7, and Core i5 chips. The rest of the lineup which includes Core i3, Pentium & Celeron series will not offer PCIe Gen 4.0 support and will retain Gen 3.0 compliancy since they are part of the Comet Lake family. Only Intel’s Rocket Lake CPUs have the architectural upgrades necessary to support PCIe Gen 4.0.
