Intel may be preparing to bring its "Core Ultra 4000 Series" naming convention beyond desktop processors and into its enthusiast-focused Nova Lake-HX mobile lineup. If the latest reports are accurate, the higher-end mobile chips would move to four-digit model numbers rather than continuing with the three-digit format currently associated with recent Core Ultra generations. The change would mark another shift in Intel's increasingly complex processor naming strategy as Nova Lake approaches.
The information comes from serial leaker Jaykihn, who shared the claim on X. According to the leak, Intel appears to be revisiting a naming style that resembles the conventions used during several older Core generations. While the architecture and branding have changed considerably since then, the return to four-digit model numbers would certainly feel familiar to long-time PC enthusiasts.
Nova Lake-HX Could Adopt Four-Digit Model Numbers
The reported change would specifically affect the Nova Lake-HX mobile segment, which is expected to target high-performance laptops and enthusiast-class systems. Instead of a model name built around three digits, these processors would reportedly fall under the Core Ultra 4000 Series branding. That would distinguish them from other Nova Lake mobile chips using a different numbering format.
This approach could help Intel separate its highest-performance mobile processors more clearly from mainstream notebook parts. HX processors typically sit closer to desktop-class performance levels, so a different naming structure could make sense from a segmentation perspective. However, it could also make Intel's broader product naming system more complicated for consumers trying to understand the differences between various mobile families.
A Return To An Older Intel Naming Style
Intel has used four-digit processor names extensively in the past. Generations such as Sandy Bridge, Ivy Bridge and Haswell all relied on four-digit Core model numbers, and that general approach continued through the company's 9th Generation Coffee Lake-S processors. Intel later moved into five-digit naming before eventually transitioning towards the newer Core Ultra branding.
The company's recent Arrow Lake desktop generation moved to three-digit names such as the Core Ultra 5 250K Plus, Core Ultra 7 270K Plus and Core Ultra 9 285K. If Nova Lake-HX does indeed adopt four digits, Arrow Lake could end up standing out as one of the relatively few modern Intel generations using that particular three-digit desktop naming format.
Nova Lake-S Desktop Names Have Also Been Leaked
The rumoured mobile naming strategy appears to line up with previously leaked Nova Lake-S desktop SKUs. Among the models reportedly being prepared are the Core Ultra 9 4970K BFC, Core Ultra 9 4950K and Core Ultra 7 4870K BFC. These names already suggest that Intel intends to move into a four-digit Core Ultra numbering scheme on the desktop side.
The "BFC" suffix is believed to represent Intel's branding for what was previously referred to as bLLC, or big last level cache. This is expected to identify processors equipped with a significantly larger cache configuration. It could therefore serve a role similar to how special cache-focused variants are positioned elsewhere in the enthusiast CPU market.
Nova Lake Could Bring Very High Core Counts
The Nova Lake family itself is expected to be a significant step forward in Intel's processor roadmap. Earlier reports have suggested that at least one SKU could feature as many as 52 cores. That would make Nova Lake one of Intel's most ambitious consumer CPU generations in terms of raw core count.
Such a large configuration would likely target demanding desktop and mobile workloads where heavy multi-threaded performance matters. If the high-end HX models inherit a similar architectural direction, Intel could be preparing a particularly aggressive lineup for gaming laptops, mobile workstations and enthusiast notebooks. Of course, the exact core configurations for each Nova Lake-HX SKU remain unconfirmed.
Intel Is Not Abandoning Three-Digit Naming Entirely
Despite the reported move towards four-digit names for Nova Lake-HX and Nova Lake-S, Intel is not expected to eliminate its current naming approach across the entire product range. The company has been using three-digit Core Ultra model numbers in the mobile segment since Meteor Lake, and that convention continues with Panther Lake. This suggests Intel intends to maintain multiple naming styles depending on product category.
Jaykihn claims that Nova Lake P, U and UL processors will continue using three-digit model numbers as part of the Core Ultra 400 Series. These segments are expected to cover more mainstream, thin-and-light and efficiency-focused laptops. As a result, the Nova Lake generation could simultaneously feature Core Ultra 400 Series mobile parts and Core Ultra 4000 Series products at the higher end.
Different Names For Different Market Segments
If the leak is accurate, Intel's naming system will become more segmented than ever. Nova Lake P, U and UL processors would retain the Core Ultra 400 Series identity, while Nova Lake-HX and desktop Nova Lake-S chips could use Core Ultra 4000 Series naming. That would give Intel a way to differentiate product tiers without relying solely on suffixes.
The downside is that consumers may need to pay closer attention to the full model name when comparing processors. A Core Ultra 400-series chip and a Core Ultra 4000-series model could belong to the same broad architectural generation while targeting very different performance classes. The naming may make more sense internally for Intel, but clear marketing will be important if the company wants buyers to understand the distinction.
Final Thoughts
Intel's reported decision to extend Core Ultra 4000 Series naming to Nova Lake-HX suggests the company is preparing another major adjustment to its processor branding. The move would give high-end desktop and mobile CPUs four-digit names while mainstream Nova Lake P, U and UL processors continue under the three-digit Core Ultra 400 Series. It would also bring back a naming style that long-time Intel users may remember from earlier Core generations.
For now, the information remains unofficial and comes through leaks rather than a formal Intel announcement. Even so, the reported Nova Lake-S names, the BFC cache branding and the possibility of a 52-core flagship all point towards a substantial next-generation lineup. If these rumours prove accurate, Intel's upcoming processors could be notable not only for their architecture and performance, but also for another reshuffling of the company's naming system.
