AMD to Use Ryzen AI Branding for All Laptop CPUs: No More U, H, or HS Segmenting

AMD will allegedly abandon the U, H, and HS branding in favor of the Ryzen AI nomenclature for all mobile SKUs from 15W to 45W. The latest report from Weibo (Lenovo’s China manager) claims that Team Red will no longer distinguish between the different power levels, using the same name for the 15W, 35W, and 45W variants. The HX branding will be retained, but it’ll be used for Strix Point (and potentially Strix Halo) on the higher-end models (a guess).

Let’s pay attention, starting from Strix Point, AMD will no longer distinguish between U, HS, and H, but use one SKU to eat the standard TDP 15W-45W, which helps to reduce the complexity of operation and testing, but for users, it is not possible to simply distinguish the performance release level of different laptops through U/HS/H, everyone must keep their eyes open. The name HX will be retained, but as you can see, the current HX is not the same as the HX of the past. Expand

Mobile processors have been divided into U and H series segments for what feels like an eternity. The U-series chips have a TDP of 15-28W, while the H lineups run at 45W and above. The HS offerings are cTDP variants of H with a 35W TDP. The HX parts are repurposed desktop chips with a TDP of 55-75W. These tend to cost the most and aren’t truly mobile, at least Intel’s variants aren’t.

AMD’s Zen 4 mobile family consisted of Phoenix-> Ryzen 7040 (28W and 35-54W) and Dragon Range->Ryzen 7045 (55-74W), while the rest were older Zen 3/Zen 2 rebrands. Hawk Point-> Ryzen 8040 is another Zen 4 lineup with the same base specs and TDP segments as Phoenix.

The Ryzen 7040 and 8040 processors feature the U, H, and HS suffixes for the 28W, 45W, and 35W SKUs, while the 7045 employs the HX suffix, implying a TDP of 55W and higher.

With the latest branding, it’ll be hard to tell which SKU you’re looking at without checking the TDP and specs of the SoC. The fact that the HX naming has been relegated to the 35W-45W (previously HS/H) Strix Point/Strix Halo SKUs will make it even more confusing.
