Intel is preparing to give its next-generation Core Ultra Series 4 “Nova Lake-S” desktop processors not one, but two enthusiast-segment desktop motherboard chipsets, the Z990 and Z970. The new processors introduce Socket LGA1954, which will require a motherboard upgrade. The idea behind segmenting Z990 and Z970 to succeed the current Z890 is to probably bring enthusiast features such as CPU overclocking to a wider market segment.
There is no word on how the Z990 and Z970 are differentiated, but VideoCardz reports that the Z970 is based on a physically smaller chip resembling the mid-tier B960 chipset that succeeds the current B860. The difference between the two could hence be I/O. The Z990 could feature a larger number of platform PCIe lanes, and have a wider 8-lane DMI chipset bus, whereas the Z970 could have fewer PCIe lanes, and a 4-lane DMI bus, just like the B960, but with the added CPU overclocking capability. This chipset would hence be suitable for those who want enthusiast features but don’t need an elaborate I/O. We still don’t know the exact PCIe lane counts of Intel’s 900-series chipset, so we can’t tabulate them.
