AMD’s next-gen Zen 5 processors are getting a branding update (at least the mobility chips are), from Ryzen 9x45HX to Ryzen AI 5/7/9 1xx. ASUS leaked this info on its Vivobook S OLED product page, revealing the new Zen 5 mobility branding. The leaked listing only includes a Strix Halo/Fire Range processor, the Ryzen AI 9 HX 170. This SKU offers 12 cores (24 threads) clocked at a peak boost clock of 5.1GHz, with 36MB of L2+L3 cache.
Update: Apparently, this is Strix Point, implying a hybrid core architecture with 4x Zen 5 (P-cores) and 8x Zen 5c (E-cores). Unlike Intel’s hybrid core design, AMD’s P and E-cores share the same architecture and instruction support. The only difference is in terms of the L3 cache per CCD. It’s half as much as a standard Zen 5 CCD, replacing the freed-up space with more cores. Consequently, you get 16 cores per CCD, up from 8.
AMD Ryzen AI 9 HX 170: Strix/Dragon Range in Action?
The primary highlight of the leak is the “Ryzen AI” performance which is rated at up to 77 TOPs. The bare NPU throughput is specced at 45 TOPs (XDNA 2), but when including the CPU and GPU capabilities, it’s buoyed up to 77 TOPs. That’s 4x higher than the 11 TOP NPU featured on the Core Ultra 7 165H, and 2.8x more than the 16 TOPs offered by the Ryzen 9 8945HS NPU. If you include the CPU and GPU throughput, it comes up to a lead of 2.4x and 2x over Meteor Lake and Hawk Point, respectively.
The Ryzen AI HX 170 is paired with 32GB of LPDDR5X soldered memory (maximum), a 16-inch 3.2K (3200×2000) OLED display with 500 nits of peak HDR brightness, and 120MHz refresh rate. The laptop weighs 1.5kg (3.31lbs) and has a 75WHrs, 4S1P, 4-cell Li-ion battery. It is fed by a TYPE-C, 90W AC adapter, making it considerably more power efficient than the 240W SAC adapter used for the Intel Core i9-14900HX range.
