Amd S New Ryzen Mobile Cpu Naming Scheme Explained

AMD’s New Ryzen CPU Naming Scheme (2022)

In this article, we will try to figure out why AMD has embarked on this journey to change their processor naming scheme, as their older scheme, while complicated in a certain sense, was relatively easy to understand and comparable to their bête noire – Intel. Moreover, we would also take this opportunity to explore how the new Ryzen mobile processor naming scheme works and analyze how it fails to understand the fundamental issue users have with processor classifications.

What Is AMD’s Current CPU Naming Scheme Like?

Before we look at the new naming system, let’s have a glance at the current system of classification of AMD’s mobile processors. The first thing we realize when we look at AMD’s current mobile CPU lineup is that the new naming scheme succeeds an already confusing convention.
The older Ryzen mobile processors are all over the place. Some generations like the Ryzen 4000 (Zen 2) and Ryzen 6000 (Zen 3+) series use a staggered naming scheme, where some mobile processors have a higher series number for their product name compared to the same generation desktop SKUs. While others like the Ryzen 3000 (Zen+) and Ryzen 5000 (Zen 3) CPUs share the same numbers as the desktop chip but have a totally different manufacturing process.
Anyway, process node complications aside, let’s deconstruct the current way of naming Ryzen mobile processors. For this, we will use the current-gen Ryzen 6000 flagship processor – Ryzen 9 6980HX – as an example. The “Ryzen 9” part denotes the level of the processor in AMD’s hierarchy, which is kind of similar to Intel’s (i3, i5, and i7). The “9” puts the chip at the top of the lineup, which is divided into four different levels – Ryzen 3, Ryzen 5, Ryzen 7, and Ryzen 9. As for the next element, the “6” indicates the generation, which in this case is the sixth generation. The following “9” situates the chip in a relative sense versus other sixth-generation Ryzen 9 CPUs. So, a 6980HX will be more performant than a 6780HX. The last two digits are simply differentiators, which almost always are “00” or a step-up multiple of 5 or 10 if the preceding number isn’t enough characterization. AMD uses this method to differentiate its PRO lineup from its mainstream chips. An example being the Ryzen 7 PRO 5875U, where the “5” usually indicates an ultra-low-power mobile-class processor.
Now, what about the letters at the end of the numbers in the chip name? These letters tell you what power class the mobile chips belong to. For AMD Ryzen chips, U stands for ultra portable (15-28W), H is for high-power mobile (35-45W), and the HX denotes high-performance overclockable mobile chips (55W) with the highest power requirements.
The H-class CPUs in the Ryzen lineup are meant for mainstream power notebooks, gaming laptops, and workstations, usually paired with discrete graphics. The U-class CPUs are meant for lightweight laptops, usually relying on on-chip graphics. For AMD mainstream mobile APUs, the processor naming scheme till now has gone something like this: MicroarchitectureProcessor GenerationModel Example(First Gen) ZenRyzen 2000 seriesRyzen 2800H(Second gen) Zen+Ryzen 3000 seriesRyzen 7 3750H(Third Gen) Zen 2Ryzen 4000 seriesRyzen 7 4800H(Third Gen) Zen 2Ryzen 5000 seriesRyzen 7 5700U(Fourth Gen) Zen 3Ryzen 5000 series Ryzen 7 5800H(Fifth Gen) Zen 3+Ryzen 6000 seriesRyzen 9 6980HX As you can see here, a confusing complication has come up with these chips — many different Zen architectures have come up in the same Ryzen generation. And that means you end up with two classes of similar-sounding chips with very different innards and efficiencies. This makes it particularly difficult for buyers to distinguish between the chips unless they are well versed in computer hardware.

New Ryzen CPU Naming Scheme: What’s the Plan?

It is in this context of confusing designation and classification that AMD realized that their current naming scheme was insufficient. This sentiment was expressed by Robert Hallock, AMD’s director of technical marketing, in a recent blog post. Taking cognizance of the issue, Hallock said, “Our current naming system for Ryzen Mobile Processors was at an end. It simply could not accommodate the influx of new SOCs in new categories we’re developing.“ He further explained that the company’s new naming scheme comes at the point in time where the current scheme has multiple processor families existing in one generation with differential capabilities. And well, AMD intends to fix this with their new naming system. Hallock argued that the new system is going to be technical yet straightforward in a way, where enthusiasts should be able to decode the numbers to see what’s inside, while at the same time being easy enough for the average user to figure out that “a higher number simply connotes higher CPU performance”.
Well, the question that everyone is going to ask is – why now? We would argue that while the problems of older naming schemes could be one of the key factors influencing this decision, the larger factor is the future possibilities that AMD wants to unlock with this new naming scheme. AMD’s announcement came in the background of their claim that the volume of notebook shipments with Ryzen chips has grown 49% in just 2 years. As the mobile market becomes more important for them, it’s only logical for them to adopt a system that helps them achieve further growth.

When Does AMD Start Using the New Name Scheme?

AMD has said that the new naming scheme will be used starting from 2023 and would apply to all of their 7000 series mobile CPUs, which will span across five different market segments using five different SOCs. The first chip will be the Phoenix and Dragon Range Ryzen 7000 CPUs.
Furthermore, AMD has claimed that the new numbering system will be a long-term project and form a foundation for their mobile processors for years to come. They claim to have already “smoke-tested” it against a 5-year timeline, so we can expect this naming scheme to be in play till at least 2027.
It was only natural that AMD plans to use the new scheme to demarcate its new Zen 4-based Ryzen 7000 series processors from 2023. The company announced new motherboard chipsets for 7000-series processors. These new generation of CPUs have so many different variants that the current scheme would just not be able to handle all these different models and make. The blog post was then a sort of primer, a way to tell us that the new processor generation is going to “be” something new under the sun.

How the New AMD Ryzen Mobile CPU Naming Scheme Works?

Now that we have looked at the current-gen naming scheme and the need for a change, let’s look at what’s new with the new Ryzen mobile processor naming scheme. AMD explained that each digit within the model numbers signifies particular aspects of the chip, and when you read them together, it could tell you all the relevant information you need to know about the processor. Is that really true and how specific is this information? Let’s make sense of the new Ryzen mobile processor naming scheme below.
First up, as shown in the image below, the new naming scheme is quite similar to the current scheme. The processor name continues to include four digits and a letter suffix, where the numbers indicate the processor generation and the suffixes indicate architecture and power. AMD says that the new names will make it easier for enthusiasts to understand how powerful is a given Ryzen mobile chip.

The first digit here describes the generation’s model year. So “7” is for 2023, “8” is for 2024, and so on. AMD believes this will help people identify when the chip was originally launched and sold.

The second digit explains the family of processors. We will use “1” for Athlon Silver, “2” for Athlon Gold, and so on. In general, each family should have two potential digits: Ryzen 5 chips will be “5” and “6,” and Ryzen 7 will be “7” and “8”. Ryzen 9 chips, though, will share “8” with Ryzen 7 and have their own number, “9.”

The third digit will explain the processor architecture. Here, “2” stands for Zen 2, “3” for Zen 3 and Zen 3+, and “4” for Zen 4. This is a wholly new approach, which might be the biggest change in the naming scheme, as it will allow many different architectures to exist in the same processor generation. For example, the new Ryzen 7640U processor will be based on Zen 4 architecture. But this approach does give AMD the flexibility to include both Zen 3 and Zen 2-based CPUs in the Ryzen 7000 series.

The fourth digit, the last one, is purely a feature differentiator. It will be used to isolate the upper and lower models of a given processor. Now, we don’t have an answer to what this will entail, but it could theoretically work as an aspect of distinction if, let’s say, there is an intermediatory step-up in the architecture from Zen 3 to Zen 3+.

Finally, AMD will be using the same U (15 to 28 watts), HS (35 watts), and HX (55-watt or above) suffixes with its Ryzen 7000 mobile processors to distinguish the overarching power class.

Moreover, AMD also revealed two new additions to the power class, i.e C and E. The “C” suffix, according to the blog post, will be used for power-efficient CPUs, designed especially for Chromebooks as opposed to Windows. And the “E” suffix will be used for the forthcoming 9-watt low-power CPUs, which will most likely be used in ultra-portable laptops. Decoder Wheel shared by AMD (Image courtesy: PC Mag)

What About the Naming of AMD’s Desktop Processors?

Now, many of you must be wondering – does the new naming scheme apply only to AMD Ryzen mobile processors? If so, why? So far, AMD is rolling out this new naming scheme only for its mobile chips, starting from 2023, and has no plans to update its desktop lineup nomenclature.
This was confirmed at the release of Ryzen 7000 desktop processors, as we were given a definitive outlay of what AMD expects to do with their desktop processors in the coming years. The first four Ryzen 7000-series desktop processors — 7950X, 7900X, 7700X, 7600X — have been released, and as we have seen will not follow the new naming system. They have the exact name scheme as the preceding Ryzen 5000 series desktop lineup. This, however, doesn’t mean that the following system cannot be implemented in the future. But we believe that the chances of this being adopted in the desktop space are unlikely. Why? Well, that’s because desktop chips are much simpler than mobile processors as they don’t have power limits or size constraints.
So while mobile processors need to have different configurations for different types of laptop configs, ranging from ultrabooks to gaming laptops, desktop chips only need to be made for a single type of setup. This means most desktop processors come in a single power variant and use common design principles throughout the lineup, escaping any need for niche classification that is important in the mobile space.

AMD’s New Mobile Processor Naming Scheme Explained

The name of mobile processors have never been easy to understand. Historically, both Intel and AMD have struggled to keep their mobile chip lineups straight, as many a time, they have turned out to be confusing, and in some aspects, overwhelming. One only has to go back a few years, when Intel launched the M-series CPUs. What category did the Intel M lineup of processors lie in? How did they differ from the U lineup? Intel never gave us the answers, and now are most probably lost in the sands of time.
So the fact that AMD has tried to make this labyrinth of mobile processors more legible is commendable. But have they really succeeded at this task? We don’t think so. Instead, we believe that a lot of consumers will make mistakes when purchasing these CPUs, as they aren’t as easy to make sense of as AMD would claim. The fact that important information like the process node (hidden in the numbers) is hard even for experienced PC enthusiasts to make out, we can only imagine how it would be for an average user.
