The headline fact: a socket change
Tom's Hardware reports that Nova Lake-S uses a new socket, LGA 1954. The outlet says the new socket is needed because Nova Lake CPUs have a significant increase in I/O and power needs. In its account, LGA 1851 ends with the Core Ultra Series 2 refresh, such as the Core Ultra 7 270K Plus released earlier in 2026. A board from that generation won't take the new chips.
Other outlets agree on the socket change. TechPowerUp says the new processors introduce Socket LGA1954, which will require a motherboard upgrade. Igor's Lab notes that Intel has not officially introduced LGA-1954. The socket's existence is therefore well corroborated, but the details are not an Intel specification sheet.
Timing: official statement vs. rumor
Intel's CEO, Lip-Bu Tan, said Nova Lake was coming at the end of 2026. That is the only official timing anchor in the material I reviewed. VideoCardz also points to Intel's public statement that Nova Lake is coming at the end of 2026.
The more specific schedule is rumor:
- Mass production in Q4 2026.
- A first launch in Q1 2027, starting with mid-range SKUs, supposedly including an unlocked 28-core part.
- Flagship models later in 2027, allegedly with two compute tiles and up to 52 cores.
Tom's Hardware also expects a lot of boards at CES 2027, with launches soon after.
One piece of supporting evidence is a compliance listing. Tom's Hardware reported on September 29, 2026 that the USB Implementers Forum now lists some of Intel's Core Ultra 400-series "Nova Lake" platforms in its Integrators List. It also reports that the PCI-SIG list includes the 900-series chipsets for Nova Lake-S. Those tests happen ahead of launches, so this suggests the platform is progressing. It doesn't confirm a date, specs or pricing.
The rumored chipset lineup
Five 900-series chipsets have been leaked: Z990, Z970, B960, W980 and Q970. The leak came from the leaker Jaykihn in February 2026. Igor's Lab states that Intel has confirmed neither the chipset names nor the technical details.
Tom's Hardware's table covers only three of the five. Here is how it compares them, with B860 and Z890 as the current-generation references:
| Item (as reported) | Z990 | Z970 | B960 | Z890 (current) |
|---|---|---|---|---|
| Total PCIe lanes | 48 | 34 | 34 | 48 |
| Chipset PCIe 5.0 lanes | 12 | 0 | 0 | 0 |
| Chipset PCIe 4.0 lanes | 12 | 14 | 14 | 24 |
| DMI link (Tom's Hardware) | Gen5 x4 | Gen5 x2 | Gen5 x2 | 8x Gen4 |
| SATA ports | 8 | 4 | 4 | 8 |
| CPU (multiplier) overclocking | Yes | Yes | No | Yes |
| BCLK overclocking | Yes | No | No | Yes |
| Memory overclocking | Yes | Yes | Yes | Yes |
| PCIe RAID | Yes | No | No | Yes |
Treat these as leaked "up to" figures. Per-port USB counts in the table are partly marked with tildes because they're uncertain.
Z990: the flagship
The leaked Z990 offers more of everything: more PCIe lanes, a wider DMI link, more SATA ports and BCLK overclocking. Tom's Hardware describes it as still the flagship, with more PCIe lanes, a DMI Gen5 x4 link, and 12 Gen5 lanes from the chipset. The 12 chipset PCIe 5.0 lanes are the big change from Z890, which has none. In theory they let board makers add several Gen5 M.2 slots without taking bandwidth from the graphics slot. Tom's Hardware says up to five Gen5 M.2 sockets are possible in principle across CPU and chipset lanes.
That figure is a ceiling, not a feature of every board. How lanes are divided among slots, M.2 sockets and onboard controllers is up to each manufacturer. The manual for a specific board will be the real authority on what runs at full speed at once.
Z970 and B960: same silicon, different permissions
Tom's Hardware reports that Z970 is the less expensive enthusiast option, reportedly built on the same silicon as B960. VideoCardz made the same claim earlier, and suggested it points to segmentation through firmware and board features rather than a separate silicon design. That is an inference, and Intel hasn't outlined it.
The reported difference is overclocking. Z970 keeps CPU multiplier overclocking and drops BCLK tuning. Igor's Lab reads the leak as Z970 supporting CPU and memory overclocking, while B960 only supports memory overclocking. If that holds, it would lower the entry price for an overclocking-ready board, which is the argument KitGuru makes. That is its opinion and not a confirmed outcome.
Reports differ on DMI width
The leaked sources disagree on one detail. Tom's Hardware's new table lists a DMI Gen5 x2 link for Z970 and B960. TechPowerUp's earlier speculation put the Z990 on a wider 8-lane DMI bus and the Z970 on a 4-lane one, like B960. KitGuru's account of the leak matches the x4 versus x2 split instead. This was early speculation that later leak tables appear to have superseded, but it shows why individual numbers shouldn't be treated as settled.
Chipset package and power
The rumored Nova Point package is smaller than Z890, at 600 mm² versus 658 mm². The die inside shrinks to 72.5 mm² from 92.9 mm², roughly 22% smaller. Base power reportedly rises to 7.9 W from 6 W, with a maximum of 14 W under load.
Tom's Hardware ties this to rumored active-cooling guidelines for the chipset. It worries that some boards could end up with small chipset fans, and recalls early X570. That is the author's speculation. If it plays out, it would be a practical annoyance, since small fans can be noisy. Check reviews for fan noise before buying a Z990 board.
CPU-side platform details
The reported CPU-side details are also unofficial:
- PCIe 5.0: Tom's Hardware says Nova Lake CPUs are said to offer 36 Gen5 lanes. That covers 16 for graphics, 8 for storage, 8 for two Thunderbolt 5 controllers and 4 for the DMI link. KitGuru's coverage of the earlier leak instead cites up to 32 Gen5 lanes. The numbers vary because the lane tally depends on what is counted, and no source is final.
- Memory: Tom's Hardware says the base memory speed is DDR5-8000, up 800 MT/s over the Arrow Lake refresh. Igor's Lab cites an ECS mockup with the B960 chipset and DDR5-8000 as making this more tangible. Tom's Hardware says slower DDR5 should still run, with a performance ceiling. Its claim that a DDR5-8000 kit costs at least $700 is a market-price remark, not a platform specification. Prices change, so check current listings.
- Thunderbolt 5: Boards may include it through a controller such as Intel's JHL9580. Tom's Hardware cites up to 80 Gbps bidirectional, or up to 120 Gbps in a one-way boost mode. Whether a given board has it depends on the board, not the chipset. Z990 reportedly supports two TB5 connections, while Z970 and B960 have one.
- Networking: Expect mostly 2.5GbE and 5GbE, with some 1GbE on cheap boards and 10GbE on premium ones. Wi-Fi 7 should be common, and cheaper boards may use 160 MHz channels. You need a Wi-Fi 7 router to benefit.
Which boards have been spotted
Board evidence is thin. Tom's Hardware cites Gigabyte listings in the Eurasian Economic Union database, reportedly 24 SKUs, via VideoCardz. It also cites ASRock shipping records, reported by Club386, covering six models. Names in those listings include:
- Gigabyte: Aorus Xtreme, Master, Pro, Elite, Stealth, Eagle, Duo X and Aero.
- ASRock: Taichi, Taichi Creator, Pro RS WiFi, Z990 Challenger and Steel Legend variants.
A database entry doesn't guarantee a board will be released, or sold in the US. The lists show no Z970 or B960 boards from ASRock and no Micro ATX or Mini-ITX models. Asus and MSI haven't been heard from. The product families Tom's Hardware expects from them, such as ROG Maximus and MSI's Godlike and Tomahawk, are the author's educated guesses, not leaks.
One earlier data point: Wccftech reported the first Q970 motherboard specifications via @momomo_us. That listing shows a workstation-oriented board with vPro and DDR5 CUDIMM support.
What this means if you're planning a build
- Don't plan a CPU-only upgrade from LGA 1851. The socket is different. That's the firmest conclusion here.
- Don't buy memory on rumors. DDR5-8000 as a base speed is reported, not confirmed. Check the CPU's memory specification and the board's qualified vendor list once they exist.
- Don't treat lane counts as board features. A chipset's maximum says little about which M.2 slots and ports work at once. Read the manual's lane-sharing notes.
- Expect higher prices. Tom's Hardware says it's safe to assume most boards will cost more, or with luck about the same. That's the author's judgment, not a quote from any source. The article's bigger point is that RAM, GPU and storage prices are already high.
- Wait for official specs. If your current system is capable, the sensible move is to wait for Intel's launch details, board lineups, benchmarks and prices.
The platform looks aimed at people who want lots of Gen5 storage and fast external connectivity. Everyone else can reasonably wait. The first real answers should come at CES 2027, if the rumored schedule holds.
