The American multinational semiconductor company AMD (Advanced Micro Devices) announced its plans to introduce a new naming system for its high-demand mobile processors.

In 2023, The forthcoming categories of new processors like Mendocino, Rembrandt-R, and Dragon range will be named differently.

According to the AMD, the inability of the current system to accommodate the new System On Chip (SOC) designs in the upcoming categories is the reason for this upheaval.

AMD introduces a ‘decoder ring’ mapped to the chipset’s nomenclature to relay a brief idea about what the customer should expect. It will help customers buy suitable chipsets just by looking at the title.

All digits and letters of a specific chipset model number correspond to relevant information regarding the quality, build and type, etc.

The new system goes as follows:

  • A processor that starts with the name ‘7xxx’ represents the latest AMD product from the 2023 portfolio.
  • If a processor is titled ‘AMD Ryzen xx4x’, the chip contains a Zen4 Rhyzen 7000 processor.
  • If you find a processor that goes by the name ‘AMD Ryzen xx30’, it suggests the processor is ‘Zen 3’ CPU microarchitecture.
  • The title ‘Ryzen xx35’ suggests that the processor falls in the category Zen 3+.

In short, the bigger the number of the series, the better CPU performance is on deck.

The Decoder Ring

The decoder ring contains the relevant information a customer needs before buying the right AMD product. It will give you significant insight, such as:

Portfolio Year: A portfolio year will tell you whether your product is recent or from an earlier catalog. In an imaginary chipset named Ryzen 5 7640U, the number 7 corresponds to the portfolio model year.

7 is the code number for 2023, 8 is for 2024 and 9 is for 2025, and so on.

Segment: The second digit in the decoder ring of the model number stands for the segment of a particular processor. For example, in Ryzen 5 7640U, the digit 6 stands for Ryzen 6.

According to AMD, this arrangement will assist customers in making faster decisions as they can quickly check the decoder ring to know the processor segment.

Architecture: AMD has decided to earmark the third digit in the ring for more informed customers and industry specialists.

The digit 4 in Ryzen 5 7640U stands for Zen 4 CPU microarchitecture.

Feature Isolation: Feature isolation ensures two different architectures remain in various categories and are not clubbed together in the same family. It’s a ‘concession’ to architectures like ‘Zen 3” versus “Zen 3+” that only the architecture digits cannot distinguish.

In Ryzen 5 7640U, the penultimate digit 0 stands for the feature isolation.

Form Factor/TDP: It stands for the kind of design category suitable for the processor. In Ryzen 5 7640U, the last letter U stands for Ultra-thin laptop models.

Similarly, ‘C’ stands for Chromebook, HX is the 55w maximum performance variant, and ‘e’ suggests a fanless edition of the Ultra-thin processor. (c)
