The AMD A9-9425 SoC is a mobile processor with 2 cores, launched in May 2016. It is part of the A9 lineup, using the Stoney Ridge architecture with Socket FT4. A9-9425 SoC has 1MB of L2 cache and operates at 3.1 GHz by default, but can boost up to 3.7 GHz, depending on the workload. AMD is making the A9-9425 SoC on a 28 nm production node using 1,200 million transistors. The multiplier is locked on A9-9425 SoC, which limits its overclocking potential.
With a TDP of 15 W, the A9-9425 SoC consumes very little energy. AMD's processor supports DDR4 memory. This processor features the Radeon R5 integrated graphics solution.
Hardware virtualization is available on the A9-9425 SoC, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
