Leak Reveals Intel 900-Series Chipset Specifications: Z990, Z970, W980, Q970, B960 for Upcoming Nova Lake Processors

Recent leaks have unveiled the details of Intel’s upcoming 900-series chipsets, which include the Z990, Z970, W980, Q970, and B960, all tailored for the anticipated Nova Lake-S Desktop CPUs set to launch in late 2026.

Overview of Intel’s 900-Series Chipsets for Nova Lake Desktops

The Intel 900-series chipsets are poised to succeed the 800-series, previously used with LGA 1851 socket motherboards for Arrow Lake and its refresh. This new series will be compatible with LGA 1954 motherboards, engineered to support the upcoming Nova Lake-S CPUs.

According to insights from Jaykihn on X, this lineup features five specialized PCH WeUs, each designed to meet various market demands. Below, we explore the specifics of these chipsets.

Specifications of Intel 900-Series Chipsets

The flagship models, Z990 and Z970, are geared towards premium builds, sporting advanced features and higher capabilities compared to other chipsets. The Z990 offers a robust configuration with:

48 PCIe lanes
Two USB4/TB4 ports
12 PCIe 5.0 and 12 PCIe 4.0 lanes
8 SATA 3.0 ports
Up to 5 USB 3.2 20 Gbps ports
Support for IA OC, BCLK, and Memory OC

Conversely, the Z970 chipset is slightly less powerful, featuring:

34 PCIe lanes and a single USB4/TB4 port
No PCIe 5.0 lanes, but includes 14 PCIe 4.0 lanes
4 SATA 3.0 ports and up to 2 USB 3.2 20 Gbps ports

While the Z970 retains IA OC and Memory OC support, BCLK OC capabilities remain exclusive to the Z990. The W980 chipset parallels the Z990 in specifications but lacks CPU overclocking capabilities, although it facilitates memory overclocking.

The Q970 chipset, aimed at business applications, provides enhanced PCIe and USB features compared to the Z970 without overclocking functionalities. Below is a summary of the overclocking capabilities across the chipsets:

Z990: IA OC ✅ / BCLK OC ✅ / Memory OC ✅
Z970: IA OC ✅ / BCLK OC ❌ / Memory OC ✅
W980: IA OC ❌ / BCLK OC ❌ / Memory OC ✅
B960: IA OC ❌ / BCLK OC ❌ / Memory OC ✅
Q970: IA OC ❌ / BCLK OC ❌ / Memory OC ❌

Intel’s approach signals a noticeable shift in strategy, positioning the Z990 chipset as a leader in high-performance capabilities. If BCLK OC is indeed supported, it may interest users with Non-K CPUs, though these consumers typically lean towards more budget-friendly options.

The B960 chipset, closely resembling the Z970 in features, will maintain essential I/O capabilities but, similar to the Q970, will forgo CPU overclocking. However, it will still support memory overclocking.

This setup indicates Intel is taking cues from AMD’s PCH classifications, with distinct differences reminiscent of AMD’s X870E and X870 chipsets. While both offer robust features, Intel ensures that key capabilities remain concentrated in a single chipset while AMD diverges slightly in architecture.

Interestingly, reports suggest that there won’t be entry-level H-series motherboards like H910 or H970 in this 900-series lineup.

As for product availability, enthusiasts and professionals can expect the announcement of the 900-series motherboards synchronized with the launch of the Nova Lake-S Desktop CPUs later this year. Additionally, some pre-launch teasers may appear at major tech events, including Computex 2026.
