Intel Z990 And Z970 Chipsets Surface as Nova Lake-S Plans Move Forward

After weeks of mixed rumors around canceled products, Intel appears to be moving forward with its next desktop platform. While reports suggest the company has scrapped the Core Ultra 9 290K Plus and the Arc B770 due to rising VRAM costs, new chipset details point to longer-term plans beyond Arrow Lake.

According to VideoCardz, Intel has added two new chipsets, Z990 and Z970, to its internal roadmap. Both chipsets reportedly target the upcoming Nova Lake-S desktop platform and introduce a brand-new socket.

Z990 and Z970 tied to LGA1954

Z990 and Z970 are both linked to the new LGA1954 socket, meaning Nova Lake-S will require entirely new motherboards. Intel has not disclosed any official specifications so far, leaving I/O capabilities, PCIe lane counts, and platform features unknown.

The two chipsets reportedly sit at the top of the stack for Nova Lake-S, with Z990 expected to serve as the flagship option. Z970 may take on a role similar to past H-series chipsets, although Intel skipped an H870 release for Arrow Lake-S.

Z970 may replace the missing H-class tier

One notable detail from the report suggests that Z970 could act as a spiritual successor to the missing H870. Intel is still expected to maintain an H-class desktop tier, but under a different naming scheme for this generation.

Z970 is also rumored to share the same underlying chipset silicon as B960. If accurate, Intel may rely on firmware limitations, BIOS options, and motherboard-level features to differentiate product tiers, rather than producing separate chipset dies. Overclocking support could remain a key divider, though Intel has not confirmed this.

Nova Lake-S targets late 2026 launch window

Both Z990 and Z970 are part of Intel’s Nova Lake-S desktop platform, which is expected to launch as the Core Ultra 400S series. Intel has already stated that Nova Lake will arrive toward the end of 2026, placing these chipsets firmly in the late-2026 desktop cycle, assuming no schedule changes.

So far, Intel has not shared official platform positioning or chipset segmentation details, leaving many questions unanswered about how Nova Lake-S systems will compare to current Arrow Lake desktops.

Beyond desktop platforms, Intel’s roadmap appears busy. Reports suggest G3 Panther Lake handheld chips could debut later this year, and the Arc B390 integrated GPU continues to dominate Linux gaming benchmarks, reinforcing Intel’s growing strength in that space despite recent cancellations.

For now, Z990 and Z970 signal that Intel’s next major desktop refresh remains on track, even as the company reshuffles parts of its product lineup.
