AMD Ryzen AI Max PRO 490 socket: FP11

What the Ryzen AI Max PRO 490 is

The Ryzen AI Max PRO 490 is a 12-core, 24-thread mobile workstation APU that AMD introduced in May 2026 in the middle of the Ryzen AI Max PRO 400 series. Its twelve uniform Zen 5 cores run at 3.2 GHz and boost to 5.0 GHz, backed by 12 MB of L2 and a large 64 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 covers local AI work.

The PRO suffix marks the commercial stack, so the chip carries AMD PRO Technologies for security, deployment and maintenance in managed fleets. The 490 mirrors the 12-core Strix Halo workstation part, the AMD Ryzen AI Max PRO 390, in cores, clocks, cache and graphics, and the documented change is the memory platform. Where the older part tops out at 128 GB, the 490 reaches 192 GB of unified LPDDR5X, with up to 160 GB assignable as graphics memory for large resident models.

Gorgon Halo keeps 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.

Against the rest of the 400 series, the 490 is the balanced choice. It doubles the CPU cores and L3 cache of the 8-core entry SKU while keeping the same 32 compute unit GPU, and it stops short of the 16-core AMD Ryzen AI Max+ PRO 495 flagship with its faster NPU. Workloads that scale with threads but fit the midrange GPU land here.

Socket and motherboard compatibility

AMD ships the Ryzen AI Max PRO 490 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 16 cores or down to 8 cores 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. Twelve Zen 5 cores plus 32 graphics compute units make this a demanding SKU to cool 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 twelve 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.
