AMD A9-9425 SoC socket: Socket FT4

What the A9-9425 SoC is

The A9-9425 SoC is a two core, two thread mobile processor from Stoney Ridge. It launched in May 2016 with a 3.1 GHz base and up to 3.7 GHz boost at 15 W. Two cores at high clocks cover entry laptops where responsive pace matters.

One megabyte of L2 cache feeds office work. The 3.1 GHz base leads Stoney dual cores for sustained browsing, while 3.7 GHz boost lifts single thread peaks. Fifteen watts fit thin bodies.

Radeon graphics with video engines handle streaming. Single channel DDR4 keeps board costs down. The chip suits buyers who want top Stoney clocks without higher power.

On 28 nm the 9425 solders to FT4 boards. It sits above the 9420 on base and burst. Locked multiplier keeps behavior steady.

Socket and motherboard compatibility

The A9-9425 solders to Socket FT4 with no upgrade path. Laptop choice fixes the chip for life. Boards set 15 W in firmware.

Thin laptops use soldered DDR4 and SSDs. The How to find your CPU socket type guide covers BGA identification.

The A9-9420 SoC on the same socket is the slightly lower clock sibling. The A6-9230 SoC trims clocks where cost matters.

Memory, PCIe and cooling

DDR4-2133 single channel is the memory target. Bandwidth suits office tasks. Capacity follows board designs.

Eight PCIe lanes wire storage and Wi-Fi. Speeds fit thin clients.

Fifteen watts cool with a small fan. Battery life decides thin body tuning.

Upgrade paths

No CPU swap exists on soldered FT4. SSD updates extend life.

A new laptop is the path past dual cores.
