Intel is reportedly working on its next-gen Cobra Core core x86 architecture which will power future CPUs with higher performance & efficiency.
Intel Cobra Core To Succeed Royal Core, Aiming Next-Gen x86 CPUs With An Architecture That Focuses on Higher Performance & Efficiency
Intel's x86 architecture design has seen quite a lot of changes in the past few years. The company moved away from plain old monolithic designs to leveraging hybrid architectures in the form of P and E cores with the start of its 12th Gen Alder Lake CPUs which continued up till 13th & 14th Gen offerings. The company then moved to a Tile (chiplet) based design, leveraging various IPs based on various processes, and the first product was launched very recently in the form of Meteor Lake.
Now, the company is moving towards a very chiplet and Tile-heavy design process for its Lunar Lake, Arrow Lake, and next-gen Panther Lake chips. These will be the first in the process that will mark the shift towards a brand new x86 architecture known as Royal Cove (Royal Core) as has been rumored. The first product to fully implement the first generation of this new design is said to be Nova Lake which is a 2026-2027 product that launches on both mobile and desktop platforms.
Intel Desktop CPU Generations Comparison:

|---|---|---|---|---|---|---|---|---|
| Alder Lake (12th Gen) | Intel 7 | Golden Cove (P-Core) Gracemont (E-Core) | HD 700 Series | 16/24 | LGA 1700/1800 | DDR5 / DDR4 | PCIe Gen 5.0 | 2021 |
| Raptor Lake (13th Gen) | Intel 7 | Raptor Cove (P-Core) Gracemont (E-Core) | HD 700 Series | 24/32 | LGA 1700/1800 | DDR5 / DDR4 | PCIe Gen 5.0 | 2022 |
| Raptor Lake Refresh (14th Gen) | Intel 7 | Raptor Cove (P-Core) Gracemont (E-Core) | HD 700 Series | 24/32 | LGA 1700/1800 | DDR5 / DDR4 | PCIe Gen 5.0 | 2023 |
| Arrow Lake (Core Ultra 200) | TSMC N3B | Lion Cove (P-Core) Skymont (E-Core) | Xe1 (Alchemist) | 24/24 | LGA 1851 | DDR5 | PCIe Gen 5.0 | 2024 |
| Arrow Lake Refresh (Core Ultra 200 Plus) | TSMC N3B | Lion Cove (P-Core) Skymont (E-Core) | Xe1 (Alchemist) | 24/24 | LGA 1851 | DDR5 | PCIe Gen 5.0 | 2026 |
| Nova Lake (Core Ultra 400?) | TBA | Coyote Cove (P-Core) Arctic Wolf (E-Core) | Xe3 (Battlemage) | 52/52 | LGA 1954 | DDR5 | PCIe Gen 5.0 | 2026-2027? |
| Razer Lake (Core Ultra 500?) | TBA | Griffin Cove (P-Core)? Golden Eagle (E-Core)? | TBA | TBA | LGA 1954? | TBA | TBA | 2027-2028? |
| Hammer Lake (Core Ultra 700?) | TBA | TBA | TBA | TBA | LGA 1954? | TBA | TBA | 2029-2030? |
It is said that before leaving for Tenstorrent, Jim Keller worked on at least two major architecture designs for Intel. Royal Cove cores are said to be one of them and the other is reportedly Ocean Cove core though we don't hear about it anymore. Ocean Cove was revealed back in 2018 so it is likely that it was the internal codename for a current generation of products & Royal Cove is its successor but that's just speculation.
Now similarly to the previous leaks, it is revealed that Intel is also working on another next-generation core architecture which is called "Cobra". The Cobra cores are expected to be a new architecture for Intel's x86 CPUs that focuses on bringing more power efficiency and higher performance compared to other competitors on the market. It isn't told what specific families this new Cobra core will land inside but it is likely going to be after the Royal core variants which as we mentioned above, begin with Nova Lake.
The leak over at gamma0burst also showcases a visual roadmap that is based entirely on speculation based on employee profiles and recent rumors. According to that, Panther Lake, the follow-up to Arrow Lake, will utilize Cougar Cove P-Cores and Darkmont E-Cores while Nova Lake, which replaces Panther Lake, will utilize Panther Cove P-Cores and Arctic Wolf E-Cores.
It will be interesting to see how Intel evolves its next-generation x86 core architectures, especially with CPU families beyond Nova Lake. It will be a few years before we see these in action so let's all wait and see how everything goes.
