A picture of a bare PCB of an upcoming GIGABYTE Z890 AORUS Pro Ice motherboard confirms that Intel will use the Core Ultra branding for its next-generation desktop processors based on the "Arrow Lake-S" microarchitecture. The picture reveals the CPU socket area, where the Socket LGA1851 will be installed, besides the CPU VRM component, the BIOS ROM, and the DDR5 DIMM slots, among other minor components. Although incompatible with LGA1700, the new LGA1851 socket has an identical cooler mount layout to it, and retains cooler compatibility, much like LGA1200 did with LGA1151. The AORUS Pro Ice comes with four DDR5 DIMM slots, as that's the only memory standard supported by "Arrow Lake" (no DDR4 support); and the CPU VRM solution uses DrMOS.

Our older article details the I/O aspects of "Arrow Lake-S." It is almost identical to the LGA1700, except it has four additional PCIe Gen 5 lanes from the CPU, for a total of 20 Gen 5 lanes, and 12 Gen 4 lanes. All Z890 motherboards will come with an M.2 Gen 5 NVMe slot that doesn't eat into the PCI-Express 5.0 x16 PEG slot's bandwidth; and an additional Gen 4 x4 that can either be wired out as an M.2 slot, or be used to drive bandwidth-hungry onboard devices, such as discrete Thunderbolt 4 or USB4 controllers. The chipset bus continues to be DMI 4.0 x8, or 128 Gbps per direction.
