The AMD A4-9120e SoC was a mobile processor with 2 cores, launched in January 2019. It is part of the A4 lineup, using the Stoney Ridge architecture with Socket FT4. A4-9120e SoC has 1 MB of L2 cache and operates at 1500 MHz by default, but can boost up to 2.2 GHz, depending on the workload. AMD is building the A4-9120e SoC on a 28 nm production process using 1,200 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on A4-9120e SoC, which limits its overclocking capabilities.
With a TDP of 6 W, the A4-9120e SoC consumes extremely little energy. AMD's processor supports DDR4 memory with a single-channel interface. The highest officially supported memory speed is 1866 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, A4-9120e SoC uses a PCI-Express Gen 3 connection. This processor features the Radeon R3 2CU integrated graphics solution.
Hardware virtualization is available on the A4-9120e SoC, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
