The AMD FX-770K was a desktop processor with 4 cores, launched in December 2014. It is part of the FX lineup, using the Kaveri architecture with Socket FM2+. FX-770K has 4 MB of L2 cache and operates at 3.5 GHz by default, but can boost up to 3.9 GHz, depending on the workload. AMD is building the FX-770K on a 28 nm production process using 2,411 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 FX-770K, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency. With a TDP of 65 W, the FX-770K 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 2133 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, FX-770K uses a PCI-Express Gen 3 connection. This processor does not have integrated graphics, you will need a separate graphics card. Hardware virtualization is available on the FX-770K, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
