Z590 motherboards only contain PCIe Gen 4.0 compatibility with 11th generation Intel Rocket Lake Core i9, Core i7, Core i5 CPUs

In two weeks, Intel and its board partners will unveil their brand new Z590 (500 Series) motherboards that will support 11th generation Rocket Lake Desktop CPUs. The most important feature of these boards, apart from the next generation CPU support, is advanced I / O capabilities and full support for PCIe Gen 4.0 protocol.

Intel Z590 motherboards only offer PCIe Gen 4.0 compatibility when running the 11th Gen Rocket Lake Core i9, Core i7 and Core i5 desktop processors are not supported by Comet Lake Refresh Core i3 processors.

The information is listed on several Z590-based motherboards we began receiving from board members prior to the January 11 announcement. Each motherboard has a sticker on the top PCIe slot that mentions that the Gen 4.0 protocol is supported by Intel’s Rocket Lake Desktop CPUs.

According to previously leaked information covering all Intel Rocket Lake SKUs, the range will consist of Core i9, Core i7 and Core i5 chips. The rest of the series, which includes the Core i3, Pentium and Celeron series, do not offer PCIe Gen 4.0 support and will retain Gen 3.0 compliance as they are part of the Comet Lake family. Only Intel’s Rocket Lake processors have the architectural upgrades needed to support PCIe Gen 4.0.

The PCIe Gen 4.0 protocol has not yet been as big a deal on the GPUs as for PCIe-based storage devices. Next-generation PCIe 4.0 SSDs have shown tremendous performance improvements, and with technologies such as NVIDIA’s RTX IO and Microsoft’s DirectStorage for desktop computers, the interconnection protocol will definitely be used to enable faster performance and access times.

Here’s All We Know About 11th Generation Rocket Lake Desktop CPUs

Intel’s Rocket Lake-S desktop CPU platform offers support on the LGA 1200 connector, which made its debut with the 10th Gen Comet Lake-S CPUs, although it’s on 400 series motherboards. Intel Rocket Lake-S processors are starting primarily for the 500 Series motherboards, but it has been confirmed that LGA 1200 motherboards will support Rocket Lake-S CPUs, especially since the PCIe Gen 4.0 is a prominent feature of Z490 . motherboards that would only be activated using Rocket Lake-S desktop CPUs.

Motherboard makers, especially ASUS, will pay extra attention to the integration of PCIe Gen 4 hardware level on their Z590 motherboard series versus their Z490 series, as we noted here.

The Core i3 models contain 4 cores and 8 wires, but all variants except the Core i3-11100 series contain 8 MB L3 case versus 6 MB L3 case on the mentioned CPUs. The Pentium line processors contain 2 cores, 4 wires and 4 MB L3 cache, while the Celeron series will only get 2 cores and no multi-threading support. However, these chips also contain 4 MB L3 cache. The Core i3 and Pentium models feature UHD 630 graphics with 24 EUs, while the Celeron SKUs get UHD 610 graphics with 12 EUs.

The architecture for Rocket Lake CPUs is said to be Cypress Cove, which is believed to be a hybrid between the Sunny Cove and Willow Cove designs, but will include Xe Gen 12 GPU architecture. Intel’s Core i9-11900K will be the most important CPU offering in the range and expect more information about it soon. As for the launch, the motherboards will appear in retail on January 11-12, while Intel’s 11th generation processors are expected to arrive by the end of March.
