The AMD A8-3870K 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. A8-3870K has 1 MB of L2 cache per core and operates at 3 GHz. AMD is making the A8-3870K 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. You may freely adjust the unlocked multiplier on A8-3870K, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency. With a TDP of 100 W, the A8-3870K consumes a good deal of power, so decent cooling is needed. 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. This processor features the Radeon HD 6550D integrated graphics solution. Hardware virtualization is available on the A8-3870K, which greatly improves virtual machine performance.
