Memory channelsiCounted in 64-bit channels, as Intel and AMD count them. A DDR5 module has two 32-bit subchannels and makers count it as one channel. A maker that counts narrower channels and states their width is converted by the total bus width, so Qualcomm's 8 channels of 16 bits are 2. A total bus width alone is divided by 64, so AMD's 256-bit interface is 4. The maker's own count goes in the source note.

CPU PCIe lanesiUsable PCIe lanes from the processor, one row per PCIe generation. Lanes that link the CPU to the chipset are not counted. If the maker gives only a total, a review that lists the split may be used, and the source note names it. When the package also holds the chipset, as on Intel Raptor Lake U and H chips, ARK's total includes the chipset lanes. Those are not counted, so the datasheet split is used. On Intel Core Ultra chips, such as Panther Lake, the platform controller or SoC tile is part of the processor, so its lanes count.
