came across a leak that claims to show the PCI Express 4.0 performance of Intel's future Rocket Lake-S processor on a Z490 motherboard. The screenshots were posted by Asian tech site ITCooker.
Rocket Lake-S is another 14nm desktop processor series from Intel, it will hit the market in Q1 2021. Besides featuring Xe-based integrated graphics, Rocket Lake-S will also introduce PCI Express 4.0 support. Up until now, this feature is only found on the AMD platform.
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.
