AMD Ryzen AI Max PRO 485 socket: FP11

What the Ryzen AI Max PRO 485 is

The Ryzen AI Max PRO 485 is an 8-core, 16-thread mobile workstation APU that AMD introduced in May 2026 at the base of the Ryzen AI Max PRO 400 series. Its eight uniform Zen 5 cores run at 3.6 GHz and boost to 5.0 GHz, supported by 8 MB of L2 and 32 MB of L3 cache. Graphics come from AMD Radeon 8050S Graphics with 32 compute units at up to 2800 MHz, and an XDNA 2 NPU rated at up to 50 TOPS handles local AI work alongside the CPU and GPU.

The PRO suffix marks the commercial stack, so the chip carries AMD PRO Technologies for security, deployment and maintenance in managed fleets. Against the Strix Halo part it mirrors, the 8-core PRO 385 class, the 485 keeps the same core count, clocks and graphics while lifting the memory ceiling from 128 GB to 192 GB of unified LPDDR5X. That larger pool is the reason the Gorgon Halo refresh exists. Up to 160 GB of the total can be assigned as graphics memory, which lets large models and data sets stay resident on the machine instead of moving across a network.

Gorgon Halo reuses the chiplet layout of Strix Halo. Zen 5 core chiplets sit beside a large I/O die that holds the graphics engine, the NPU and the 256-bit memory controller, and AMD builds the compute silicon on the TSMC 4 nm FinFET process. The system maker sets power and cooling inside a 45 to 120 W configurable window, with 55 W as the default TDP for this SKU.

Inside the 400 series the 485 sits below the 16-core AMD Ryzen AI Max+ PRO 495, trading CPU cores and total AI throughput for a lower entry cost into the 192 GB memory platform. Buyers who need thread count first step up the stack, while buyers who need memory capacity per dollar start here. The 32 compute unit GPU stays constant across the 8-core and 12-core PRO SKUs, so the choice between them rests on CPU and cache rather than graphics.

Socket and motherboard compatibility

AMD ships the Ryzen AI Max PRO 485 only as a soldered part for FP11, which means the processor arrives fixed to the board and it cannot be replaced or upgraded in the field. Assembly solders all 2,077 balls of the 37.5 × 45 mm package in one factory step, and the thermal design is validated for that single configuration through the service life of the machine.

There is no board or chipset choice in the retail sense. The vendor selects the soldered memory capacity, tunes the firmware and validates the thermal design for the 45 to 120 W window. Moving to a higher core count means a different board build, not a part swap, even though the 400 series SKUs share the FP11 package. Readers new to soldered packages can review LGA, PGA and BGA: CPU package types explained for how a ball grid array differs from a socketed desktop part.

The FP11 footprint is shared with the embedded branch of Halo silicon, including long lifecycle parts such as the AMD Ryzen AI Embedded X188i, which suits equipment vendors with extended service schedules. The smaller FP8 package covers lower power laptops with narrower memory buses. Halo boards stay distinct from those mainstream designs by memory width, package size and power class.

Memory, PCIe and cooling

Memory is soldered LPDDR5X up to 8533 MT/s on a 256-bit bus, with up to 192 GB in one unified pool shared by the CPU cores, the 32 compute unit graphics engine and the NPU. Up to 160 GB of that pool can be dedicated to graphics workloads, which is the configuration that runs very large local models on a single machine. Capacity and speed are fixed when the board is built, so they rank with the SKU as permanent choices that deserve planning before purchase.

Expansion comes from 16 PCIe Gen4 lanes from the SoC, which typically serve NVMe storage and high speed peripherals. Display and parallel compute run on the integrated Radeon graphics, so the lanes stay free for storage and I/O duties. The exact lane split and port list are set per machine design, so the vendor specification governs.

Cooling is a system responsibility across the 45 to 120 W configurable range. Eight Zen 5 cores plus 32 graphics compute units still demand a serious heatsink and fan design in a thin chassis, so chassis choice decides how long the chip holds peak clocks under combined load. There is no boxed cooler and no retail heatsink list for a soldered mobile APU.

Upgrade paths

There is no CPU upgrade path on a soldered package. When eight cores stop being enough, the step inside the 400 series is a different class of machine built around the 16-core AMD Ryzen AI Max+ PRO 495, since memory capacity already matches across the stack. A board replacement is the only route, and it carries new memory and firmware with it.

Moving off FP11 means a new platform. Lower power business laptops use narrower memory buses and smaller packages, while socketed desktop builders meet related Zen 5 silicon on boards such as AM5. Because memory is soldered on FP11, even a memory size change means a new board, so capacity planning belongs at the start of the project rather than at the end.
