AMD is developing a new laptop processor named the Ryzen AI 7 HX 455, featuring an integrated GPU with 16 compute units, according to information reported by Jagat Review citing a leak from Golden Pig Upgrade on Weibo.
Ryzen AI 7 HX 455 Processor Specifications and Graphics
The upcoming APU belongs to the Ryzen AI 400 family based on the Gorgon Point architecture. According to Jagat Review, the processor packs eight CPU cores and 16 threads alongside a 24MB L3 cache. Its standout feature is the integrated GPU, which is expected to sport 16 compute units and potentially utilize the Radeon 890M architecture. This configuration places its graphics capability close to higher-tier Ryzen AI 9 variants like the HX 470 and HX 475, providing a performance boost for thin laptops relying on integrated graphics.
Comparison with Ryzen AI 7 450 and Ryzen Z2 Extreme
While sharing an eight-core and 16-thread layout with the standard Ryzen AI 7 450, the HX 455 distinguishes itself with a larger L3 cache and a higher compute unit count in its iGPU. Jagat Review noted that the processor also shares similarities with the Ryzen Z2 Extreme chip used in gaming handheld devices, though the HX 455 features a 24MB L3 cache compared to the 16MB found in the Z2 Extreme.
Ryzen AI Max 400 Series and High-Capacity Memory Systems
AMD also offers the Ryzen AI Max 400 and Ryzen AI Max PRO 400 Series processors, featuring up to 16 Zen 5 CPU cores, 32 threads, a 55 TOPS NPU, and 40 GPU compute units. These systems utilize the Radeon 8065S integrated graphics and support up to 192GB of unified LPDDR5X memory via a 256-bit interface, allowing up to 160GB to be allocated for GPU workloads. This represents an increase from previous generation systems that held a maximum of 128GB total memory with up to 96GB dedicated to the GPU. The Ryzen AI Max PRO 400 Series functions as an x86 client processor capable of running models with over 300 billion parameters at 4-bit quantization locally without shifting processing to the cloud. Manufacturers including Minisforum and HP have adopted these processors in devices such as the Minisforum MS-S1 MAX-P495 workstation and the HP ZBook Ultra G3a 16 mobile workstation.
