AMD Ryzen AI Max 385

AMD Ryzen AI Max 385

The AMD Ryzen AI Max 385 is a powerful Strix Halo family processor that debuted in January 2025. The APU comes equipped with 8 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. Other noteworthy features include PCIe 4, USB 4 and LPDDR5x-8000 RAM support.

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 had. The integrated XDNA 2 NPU delivers up to 50 INT8 TOPS for accelerating various AI workloads. The CPU's L3 cache is fairly large at 32 MB. That being said, the higher-end 390 and 395 AI Max chips have twice the amount.

Performance

Its CPU performance should be about as good as the fastest Qualcomm Snapdragon X chips, like the X1E-84-100.

Graphics

The Radeon 8050S sports 32 RDNA 3+ architecture CUs (2048 unified shaders) that could see it competing with entry-level and 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 385 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.
