Once you grasp the intricacies of these numbers, you’ll be able to select the perfect CPU for your needs without requiring external assistance.

Starting in 2023, affordable computing products will be simply branded as Intel® Processor, instead of Intel® Pentium® and Intel® Celeron® processor as they focus more on flagship brands, including Intel® Core™, Intel® Evo™, and Intel vPro®.


The Intel naming scheme starts with the processor’s brand—the overall product line the processor was created for. Such as – Intel® Core™ or the new brand naming convention – Intel® Processor, or Intel® Xeon® processors offer a higher level of performance for servers and workstations.

Brand Modifier

The Intel® Core™ processor series includes the brand modifiers i3, i5, i7, and i9. Higher brand modifier numbers offer a higher level of performance and, in some cases, additional features (like Intel® Hyper-Threading Technology). For example, within a given processor family, an i9 will outperform an i7, which will outperform an i5, and outperform i3.

Generation Indicator

After the brand and brand modifier comes the processor’s Generation indicator. Intel® Processor generations are identified in the processor number in most Intel® Core™ processor brands, with the generation being listed after the dash. When a processor has four or five digits, the first one or two digits represent the generation. For example, a processor with the digits 9700 is a 9th Gen processor, while one labeled 12800 is a 12th Gen processor.

SKU Numeric Digits

For the majority of Intel® processors, the final three digits of the product number are the SKU. SKUs are generally assigned in the order in which processors in that generation and product line are developed. A higher SKU within otherwise identical processor brands and generations will generally have more features.

Product Line Suffix

These remaining differences are indicated by a letter-based product line suffix. For example, within the Intel® Core™ processor series,

  • U or M indicates a processor that has been designed for power-efficient laptops or 2-in-1s,.
  • H, HS series CPUs are designed with Gaming Performance in mind.
  • K series CPUs are designed for overclocking capabilities.
  • Meanwhile, XE indicates an “extreme edition” processor for desktops designed for maximum performance.

Starting this year, AMD has introduced a new nomenclature for their mobile CPUs. Understanding this naming scheme will be of great assistance when evaluating an AMD laptop. On paper, distinguishing the performance disparity between, say, a 7640U and a 7630U may not be immediately apparent. Let’s delve into this to gain better clarity.

First Digit: The Year of Introduction

As clearly depicted, AMD’s nomenclature for their mobile CPUs follows a logical pattern. The first digit in the model name no longer designates the generation but signifies the year of introduction. For instance, if it begins with seven, it corresponds to a model unveiled in 2023; if it starts with eight, it signifies a CPU introduced in 2024, and so forth. Take the processor illustrated in the figure as an example, denoted as 7640, indicating its launch year of 2023 due to the leading digit being seven.

The Second Digit: Identifying the Segment

The second digit in the model name retains its previous significance, denoting the processor segment. If it’s nine, the processor is categorized as a Ryzen 9; for instance, the processor in the figure is designated as five, signifying a Ryzen 5 processor.

The Third Digit: Unveiling the Architecture

This digit holds the key to representing the processor’s performance level, specifically denoting the architecture employed. If it’s 4, it indicates the utilization of the Zen 4 architecture, AMD’s most advanced architecture. If it’s three, it signifies a processor featuring Zen 3 or Zen 3+ architecture, exemplified by the 5000 or 6000 series. In the provided example, 7640U signifies the utilization of the latest Zen 4 architecture.

The Fourth Digit: Distinction Between Similar Segments

The last digit in the model name serves to distinguish CPUs within the same segment. A higher digit implies increased performance and a higher price. For instance, if two CPUs are denoted as 7940HX and 7945HX, the latter, with the higher last digit, should deliver superior performance at a higher price.

The Last: Series Identification

The final letter in the model name retains its previous role, signifying the product series. “U” designates processors tailored for thin-and-light laptops; “HS” signifies a higher-performance model with a slimmer chassis, while “HX” is reserved for the most powerful laptops in the field.
