The AMD Athlon II X4 641 was a desktop processor with 4 cores, launched in February 2012. It is part of the Athlon II X4 lineup, using the Llano architecture with Socket FM1. Athlon II X4 641 has 1 MB of L2 cache per core and operates at 2.8 GHz. AMD is building the Athlon II X4 641 on a 32 nm production process 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 Athlon II X4 641, which limits its overclocking capabilities.
With a TDP of 100 W, the Athlon II X4 641 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. For communication with other components in the machine, Athlon II X4 641 uses a PCI-Express Gen 2 connection. This processor does not have integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Athlon II X4 641, which greatly improves virtual machine performance.
