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 1 MB of L2 cache per core 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 MT/s, 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.
