Intel's current generation mobile processor product stack is vast, to say the least. In Q4-2023, the company launched its Core Ultra "Meteor Lake" mobile processors spanning the U-segment (7 W to 28 W), and H-segment (35 W to 45 W). Today, the company capped the upper end of the stack with the 14th Gen Core HX-series mobile processors based on "Raptor Lake Refresh," which dial up core counts to 8P+16E. And now, the company is adding more choice to the U-segment with the Core Processor Series 1, based on a lower core-count variant of the "Raptor Lake Refresh" architecture.

The Core Processor Series 1 follows the same nomenclature as the Core Ultra, where the "Ultra" denotes the latest "Meteor Lake" architecture. Processor model numbering and case badges are similar between Core Processor Series 1 and Core Ultra, except the lack of the "Ultra" brand extension. These chips are built on the monolithic "Raptor Lake Refresh" dies on the Intel 7 foundry node, and lack innovations such as the Low-power Island cores, 3D Performance Hybrid architecture, the all important AI Boost and on-silicon NPU; as well as that 2x faster Arc Xe-LPG integrated graphics, but use existing combinations of "Raptor Cove" and "Gracemont" CPU cores, along with older Xe-LP graphics with up to 96 EU; and a mostly similar I/O.

Intel today announced its first major branding change for its client-segment Core desktop and mobile processor family in over 15 years (since the introduction of the very first Core "Nehalem"). "Core" still remains Intel's main client-segment processor brand, but the way the company draws its processor model numbers, is being significantly changed. The company is also introducing the Core Ultra brand of premium processors. The new nomenclature also sees Intel discontinue the use of "generations" within the SKU name.

The current Intel naming scheme sees the company mention processor generation before the main brand Core. For example, the 13th Gen Core is Intel's current line of client-segment products. Right next to Core, Intel places the brand extension "i" followed by the product tiering number 3, 5, 7, or 9. The product model number follows, and even this model number tends to begin with the processor generation. For example, the "i9-13900" already conveys that it is a processor from Intel's 13th Gen Core family. This is where Intel is making its two main changes.
