Not sure how legit this is … but someone has managed to get the PCIE 4.0 fully working and tested with an unknown Intel processor (allegedly Intel’s 11th Gen Rocket Lake-S) on an ASRock Z490 motherboard. Interesting if true.
Taken from Videocardz … The 11th Gen core series will feature Intel’s new 14nm core design (rumored Willow/Cypress Cove) and integrated Xe-LP graphics. Both represent a major transformation for Intel’s now outdated Skylake architecture. The series will also be the first to support PCI Express 4.0 devices, an interface standard that has been available to AMD 400 and 500-series platforms for a long time.
Taiwanese leakers allegedly had access to one of such ‘next-generation’ CPUs and they immediately tested it on the Z490 motherboard. Motherboard manufacturers were eager to confirm that their first LGA1200 motherboards are already hardware-ready for the new PCIe standard.
Two screenshots were posted by ITCooker, featuring Seagate FireCuda 520 PCIe 4.0 SSD and AMD Radeon RX 5700XT graphics card. Both were correctly recognized as PCIe 4.0-capable devices by Crystal Disk Mark 8 for SSD and GPU-Z for the graphics card.
A 5 GB/s sequential (Q8T1) read and 4.2 GB/s write performance were reported by CristalDiskMark. Such throughput is only available through the PCIe 4.0 interface. The GPU was stress tested with Furmark, where GPU-Z reports PCIe x16 4.0 @ x16 4.0 active bus interface. This confirms that both SSD and GPU were using the Gen4 standard.
