Intel's next-generation Panther Lake-H series of processors has recently resurfaced online, focusing this time on its naming conventions. According to the latest revelations, Intel is set to introduce a new "Ultra X" code for the Panther Lake-H lineup, including models such as Core Ultra X5, Ultra X7, and Ultra X9. This change indicates a modification in Intel's brand naming strategy once again.

Panther Lake represents a crucial generation for Intel as it debuts Intel's 18A process node paired with a new heterogeneous core architecture. Previous announcements have highlighted the use of Cougar Cove performance cores (P-Core), Darkmont efficiency cores (E-Core), and low-power LP-E cores (possibly Skymont). Additionally, they have pointed to the integration of Celestial architecture-based Xe3 GPUs and a next-generation NPU engine to enhance AI operations, including local AI computing and inference capabilities. However, the positioning and naming specifics of the SKUs have remained unclear until now, with the emergence of the "Ultra X" designation becoming a key focus.

Leaks suggest possible SKU names include Ultra X7 368H, Ultra X7 358H, Ultra X5 338H, and Ultra X9 388H. The Ultra X9 388H is rumored to be the flagship model, boasting 12 Xe3 GPU cores and clock speeds up to 5.1 GHz – marking the pinnacle of the Panther Lake-H series. The Ultra X7 model is likely aimed at high-performance integrated graphics, while the Ultra X5 series caters to mid-range demands, appealing to a broader spectrum of mainstream users.

Originally reported as part of the Nova Lake-H series, these SKUs are, according to prior roadmaps, more aligned with the Core Ultra 300 series than the Core Ultra 400 series. This suggests they are indeed within the Panther Lake-H range.

The configuration details revealed so far for Panther Lake-H indicate at least three different specification combinations: one featuring 4P+8E+4LP-E cores with 12 Xe3 GPU cores, consuming 25W (PL1) and 45W (PL2); another with 4P+8E+4LP-E including 4 Xe3 GPU cores; and a third omitting LP-E cores but retaining 4P+8E with 4 Xe3 GPU cores. Furthermore, the Panther Lake-U series offers two low-power options: 4P+4LP-E+4 Xe3 GPUs and a lighter 2P+4LP-E+4 Xe3 GPUs, designed for 15W (PL1) to 45W (PL2) power use. This stratified approach clearly aims to meet the entire spectrum of needs, from high-performing mobile workstations to ultra-slim notebooks.

The frequently shifting naming strategy may lead to some user confusion. In recent years, Intel has moved from the traditional "Core i" system to "Core Ultra," now reinstating the "X5, X7, X9" labels. This reversion may blur consumers' understanding of the generational and positional differences. Product-wise, this naming may also serve to more distinctly separate performance tiers, akin to the "60/70/90" series division standard in the GPU market.

Panther Lake-H symbolizes Intel's inaugural use of the 18A node, tasked with showcasing progression in both process and architecture. Its P-core and E-core amalgamation, integrated Xe3 GPU, and fortified AI NPU are key modules aimed at fulfilling market demands over the next few years. More comprehensive insights into this processor generation are anticipated in an official announcement this month, resolving whether the Ultra X naming becomes permanent and clarifying the market placement of individual SKUs. For users invested in the notebook and mobile processor domains, this event will mark a significant indication of Intel's forthcoming strategic intentions.
