AMD Ryzen AI Max+ PRO 395 socket: FP11

What the Ryzen AI Max+ PRO 395 is

The Ryzen AI Max+ PRO 395 is a 16-core, 32-thread mobile workstation APU that AMD launched in January 2025 at the head of the PRO branch of Strix Halo silicon. Its sixteen uniform Zen 5 cores run at 3.0 GHz and boost to 5.1 GHz, backed by 16 MB of L2 and 64 MB of L3 cache for 80 MB of total cache. Graphics come from AMD Radeon 8060S Graphics with the full 40 compute units at up to 2900 MHz, and an XDNA 2 NPU rated at up to 50 TOPS covers local AI work.

The PRO suffix marks the business stack. The chip carries AMD PRO Technologies for security, deployment and maintenance in managed fleets, while its clocks, core count and graphics match the consumer Ryzen AI Max+ 395. That pairing lets IT departments standardize on one performance profile across commercial laptops and mini workstations. Total platform AI throughput is rated at up to 126 TOPS across CPU, GPU and NPU, the highest of the 300 series PRO parts.

Strix Halo is a chiplet design. Two 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 laptop or workstation maker sets power and cooling inside a 45 to 120 W configurable window, with 55 W as the default TDP for this SKU.

Against its PRO siblings, the 395 adds four CPU cores over the 12-core AMD Ryzen AI Max PRO 390 while keeping the same 5.0 GHz class boost behavior and stepping the GPU from 32 to 40 compute units. Multithreaded compiles, simulations and data preparation scale with those cores, and GPU bound work gains from the wider graphics engine. Buyers choose between them on thread count, cache and graphics width together.

Socket and motherboard compatibility

AMD ships the Ryzen AI Max+ PRO 395 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 cooling for the 45 to 120 W window. Moving to a different core count means a different board build, not a part swap, even though the Strix Halo PRO 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 Gorgon Halo refresh later reused the same footprint with a higher memory ceiling, led by the 16-core AMD Ryzen AI Max+ PRO 495. Halo boards stay distinct from mainstream thin laptop designs by memory width, package size and power class.

Memory, PCIe and cooling

Memory is soldered LPDDR5X up to 8000 MT/s on a 256-bit bus, with up to 128 GB in one unified pool shared by the CPU cores, the 40 compute unit graphics engine and the NPU. Up to 96 GB of that pool can be reserved for graphics workloads on the 300 series platform. 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. Sixteen Zen 5 cores plus a full 40 compute unit GPU make this the hardest Strix Halo PRO SKU to cool, 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. This SKU already tops the Strix Halo PRO branch in cores, cache and graphics, so a faster chip means a new board or a new workstation. When the workload shrinks, the 12-core AMD Ryzen AI Max PRO 390 is the step down with the same memory platform and a smaller GPU.

Moving off FP11 means a new platform. The Gorgon Halo generation raises the memory ceiling to 192 GB for buyers who outgrow 128 GB, 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.
