Leaked specifications reveal Intel's upcoming 900-series chipset lineup for the Nova Lake-S platform launching toward the end of 2026. The new architecture introduces a tiered approach with B960, Z970, and flagship Z990 chipsets, mirroring AMD's strategy for enthusiast and mainstream segments. The B960 and Z970 share a common physical silicon design, differing primarily in CPU overclocking support.

Intel's B960 mainstream chipset succeeds the current B860 with a smaller PCH silicon featuring DMI Gen 5 x2 connectivity at 64 Gbps per direction. Both B960 and Z970 provide 14 PCIe 4.0 downstream lanes and one 40 Gbps USB4/Thunderbolt 4 port from the processor. The Z970 adds multiplier-unlocked CPU overclocking when paired with K-series processors. The flagship Z990 doubles DMI bandwidth to 128 Gbps using DMI 5.0 x4 and introduces PCIe Gen 5 downstream lanes.

Higher-tier chipsets Z990, Q970, and W980 offer enhanced I/O capabilities including 12 PCIe Gen 5 lanes and two 40 Gbps USB4/Thunderbolt 4 ports. The Q970 targets commercial desktops with vPro support while W980 caters to workstation platforms with Xeon W-series processors. Intel appears to have abandoned the H970 chipset due to consistently low demand, focusing instead on differentiating through feature sets rather than traditional market segmentation.

Quick Fact: Intel's Nova Lake-S platform with 900-series chipsets launches toward the end of 2026.
