AMD Ryzen AI Max PRO 390

The AMD Ryzen AI Max PRO 390 is a powerful Strix Halo family processor that debuted in January 2025. The APU comes equipped with 12 Zen 5 CPU cores running at up to 5.0 GHz, the 32 CU RDNA 3+ Radeon 8050S graphics adapter and the 50 TOPS XDNA 2 neural engine. Unlike its non-PRO sibling, the chip features AMD Secure Processor (an on-package ARM security co-processor), Windows Device Guard and AMD-Vi. Other noteworthy features include PCIe 4, USB 4 and LPDDR5x-8000 RAM support and a whole lot of L3 cache.

Architecture and Features

Unlike it is with Strix Point, Strix Halo parts are powered by Zen 5 cores - no Zen 5c here. It's not clear if this is the desktop Zen 5 implementation with full AVX512 throughput or the mobile one. According to AMD, Zen 5 delivers a 16% IPC improvement over Zen 4 thanks to branch prediction improvements and other refinements.

Elsewhere, the AI Max chip supports RAM as fast as LPDDR5x-8000, and is natively compatible with USB 4 (and therefore Thunderbolt). It has PCIe 4.0 support for a throughput of 1.9 GB/s per lane, just like its 8000 series predecessors did. The integrated XDNA 2 NPU delivers up to 50 INT8 TOPS for accelerating various AI workloads.

Performance

Its CPU performance should be about 10% higher than that of the Ryzen AI 9 HX 370 and HX 375 due to the AI Max PRO chip's higher TDP power target and lack of cut-down Zen 5c cores.

Graphics

The Radeon 8050S sports 32 RDNA 3+ architecture CUs (2048 unified shaders) that could see it competing with lower mid-range desktop graphics cards like the Radeon RX 7700 XT. This GPU will undoubtedly run any game at 1080p on Ultra, however, the ultimate question is whether or not the cooling solution of the laptop will be powerful enough to let the iGPU shine.

Naturally, the Radeon is capable of driving four SUHD 4320p60 monitors. It can also efficiently encode and decode the most popular video codecs including AVC, HEVC, VP9 and AV1. The latest addition to that list, the VVC codec, is not supported unlike it is with Intel Lunar Lake chips.

Power consumption

The AI Max PRO 390 can eat up to 120 W depending on the system and its TDP power targets, with 45 W named as the minimum TDP.

The 4 nm TSMC process that the CPU cores are built with make for decent, as of Jan 2025, energy efficiency.
