The AMD A8-3820 was a desktop processor with 4 cores, launched in December 2011. It is part of the A8 lineup, using the Llano architecture with Socket FM1. A8-3820 has 1MB of L2 cache and operates at 2.5 GHz by default, but can boost up to 2.8 GHz, depending on the workload. AMD is making the A8-3820 on a 32 nm production node using 1,178 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on A8-3820, which limits its overclocking potential.
With a TDP of 65 W, the A8-3820 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 MHz, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, A8-3820 uses a PCI-Express Gen 2 connection. This processor features the Radeon HD 6550D integrated graphics solution.
Hardware virtualization is available on the A8-3820, which greatly improves virtual machine performance.
