Intel Nova Lake Desktop CPUs are the next big platform upgrade for the consumer segment, offering up to 52 cores.
Intel's 52-Core Nova Lake Desktop CPUs Made At TSMC, Consume Lots of Power & Produce Lots of Heat
Every year at Computex, we try to bring you the latest updates on Intel's next-generation desktop lineup. In 2023, we shared the first details of Intel's 14th Gen Raptor Lake Refresh CPUs, and in 2024, we shared the first details about Intel's Arrow Lake CPUs. Our information turned out to be correct, and this year, we have an update for Intel's upcoming lineup codenamed Nova Lake.
The Intel Nova Lake Desktop CPUs will be branded under the Core Ultra Series 4 or Core Ultra 400 family. This family will feature two new core architectures, the Coyote Cove P-Core and Arctic Wolf E-Core. The family will also use a mix of Xe3 and Xe3P iGPU architectures. The CPUs won't be made using Intel's own process technologies but would rather rely on TSMC. This has been the case for a few generations now & despite its Foundry's recent successes, Intel is producing the majority of its client chips for desktops at the Taiwanese semiconductor giant.
Nova Lake Moved to CES 2027
Now, coming to the more interesting information, which is the launch. Earlier, we were expecting a release of Nova Lake Desktop CPUs in the second half of 2026, but when we asked multiple friends at Computex, we were told something different. It looks like Intel is now eyeing a Q1 2027 release for the first rollout of Nova Lake CPUs. The announcement is said to take place at CES 2027, with a retail launch expected in the following weeks.
But the initial launch will only include 28-core models based on a single compute tile. The 52-core models featuring dual compute tiles will be launching at least 2-3 months later (close to Computex 2027). The volume production is yet to commence on Nova Lake, and given the current PC market situation, such as rising memory & component prices, it makes sense why the launch is pushed back.
This will also mean that Intel's Nova Lake will launch around the same time as AMD's next-gen Ryzen CPUs based on the Zen 6 core architecture. Codenamed Olympic Ridge, AMD's next-gen Ryzen chips will retain compatibility with AM5 platforms, bringing more features and unlocking up to 24 cores with 48 threads.
AMD Olympic Ridge vs Intel Nova Lake-S:
| CPUs | Intel Core Ultra 400 | AMD Ryzen 10000? |
|---|---|---|
| Family | Nova Lake-S | Olympic Ridge |
| Architecture | Coyote Cove (P-Core) Arctic Wolf (E/LP Core) | Zen 6 |
| CPU Process | TSMC N2P | TSMC N2P |
| Core Count (Max) | 52 | 24 |
| Thread Count (Max) | 52 | 48 |
| Max P-Cores | 16 | 24 |
| Max E-Cores | 32 | N/A |
| Max LP-E Cores | 4 | N/A |
| Max Cache (L2+L3) | 160-320 MB | 96 MB L3 |
| Max bLLC Cache | 144-288 MB | 64 MB per stack? |
| DDR5 (1DPC 1R) | 8000 MT/s CUDIMM - Yes | 7200 MT/s? CUDIMM - Yes |
| PCIe 5.0 Lanes (Max) | 36 | TBD |
| PCIe 4.0 Lanes (Max) | 16 | TBD |
| Socket Support | LGA 1954 | AM5 |
| Max TDP (PL1) | 125-175W | 125W+ |
| Max Power | ~700W (Dual) ~350W (Single) | TBD |
| Launch | 2H 2026 | 2H 2026 |
New OC Features & Desktop To Get SMT Back
We were also told that Intel has showcased its partners a new overclocking demo called "Multi-Core OC" which will essentially let users overclock each core individually. The initial performance tests are said to be really good, but this feature will only be available on higher core count "Unlocked" models.
Besides that, we were also told that Intel is fast-forwarding its plans to bring back SMT support on the desktop segment. We know that Intel's next-gen Datacenter CPUs, codenamed Coral Rapids, are bringing back SMT support, but those arrive around 2028.
Power & Thermals Continue To Climb On High-Core-Count SKUs
On the topic of power and thermals, it is said that Intel's Nova Lake 52-core models will feature very high power consumption. The PL1 is set to 175W, 40% higher than the existing chips, and the PL2 is around 300-400W. The PL4 limit is said to reach over 700W, and these chips will be a multi-core powerhouse for entry-level workstations and content creators. The 52-core models will also feature WS-class board designs and will tackle AMD's entry-level Threadrippers.
The thermal characteristics have also gone up, and to tackle that, we have already seen that Intel is working on its 2L (dual lever) ILM (Integrated Loading Mechanism) for the LGA 1954 socket. Unlike the concave design, the new heatspreader will be flatter and will allow more heat to pass from the IHS to the heatsink.
Z990 & Z970 Motherboards Are Real
Lastly, multiple vendors were casually carrying next-gen Intel 900-series motherboards. We were able to get to see three Z990 and two Z970 motherboards. We also got a hands-on time with one Z990 and the two Z970 motherboards. We can't say which brand these were from nor share the pictures, but you must have already seen a few doing the rounds online.
The Z990 motherboard we saw was a very final design, but we were told that changes are to be made & as such, the vendor asked us to consider it a prototype. The board used two 8-pin connectors for the CPU and an additional 8-pin connector for the PCIe lands. The additional connector is said to provide power to the CPU socket if necessary. One of the Z970 motherboards we saw was fairly standard in an ATX form factor, and another was bare of all components (only PCB).
The appearance of Z990 & Z970 motherboards this early shows that Intel is already evaluating its next-gen Nova Lake platforms with all of its motherboard partners. The BIOS work is being done, and DDR5 memory support is going to be way more extensive than any platforms that we have seen. IO will also feature Thunderbolt 5 ports, and this time, all M.2 and PCIe slots are going to be Gen5 (at least on the Z990 designs).
With that said, we are looking forward to Intel's Nova Lake Desktop CPUs and the respective 900-series motherboard platforms, and can't wait to try them out.
