The AMD A4-4020 was a desktop processor with 2 cores, launched in January 2014. It is part of the A4 lineup, using the Richland architecture with Socket FM2. A4-4020 has 1 MB of L2 cache and operates at 3.2 GHz by default, but can boost up to 3.4 GHz, depending on the workload. AMD is building the A4-4020 on a 32 nm production process using 1,303 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on A4-4020, which limits its overclocking capabilities.
With a TDP of 65 W, the A4-4020 consumes typical power levels for a modern PC. AMD's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1333 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer, A4-4020 uses a PCI-Express Gen 2 connection. This processor features the Radeon HD 7480D integrated graphics solution.
Hardware virtualization is available on the A4-4020, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
