"According to alleged "Rocket Lake-S" + Intel 500-series chipset platform maps leaked to the web by VideoCardz, "Rocket Lake-S" will finally take forward strides in the area of I/O. The CPU socket puts out not just its usual PEG slot (16 lanes meant for PCI-Express graphics cards), but also a CPU-attached M.2 NVMe slot with 4 PCI-Express gen 4.0 lanes, much like Socket AM4 motherboards based on AMD X570 or B550 chipsets. What's more, Intel fattened the chipset bus with 8 lanes. While the bus is still DMI 3.0 (with PCI-Express gen 3.0 physical layer), 8 lanes mean a doubling in bandwidth compared to Intel 400-series chipsets (or older). The 500-series PCH itself will still be PCI-Express gen 3.0 based, putting out only gen 3.0 downstream PCIe lanes, unlike the AMD X570, which puts out gen 4.0 downstream general purpose lanes, and uses a PCI-Express 4.0 x4 pipe to the CPU. Quite a few Intel 400-series chipset motherboards have preparation for PCIe gen 4.0 PEG slot when paired with a "Rocket Lake-S" processors."
