The AMD A4-3420 was a desktop processor with 2 cores, launched in December 2011. It is part of the A4 lineup, using the Llano architecture with Socket FM1. A4-3420 has 512 KB of L2 cache per core and operates at 2.8 GHz. AMD is making the A4-3420 on a 32 nm production node using 1,178 million transistors. The multiplier is locked on A4-3420, which limits its overclocking potential.
With a TDP of 65 W, the A4-3420 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 1866 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer, A4-3420 uses a PCI-Express Gen 2 connection. This processor features the Radeon HD 6410D integrated graphics solution.
Hardware virtualization is available on the A4-3420, which greatly improves virtual machine performance.
