The AMD Athlon X4 845 was a desktop processor with 4 cores, launched in February 2016. It is part of the Athlon lineup, using the Carrizo architecture with Socket FM2+. Athlon X4 845 has 2MB of L2 cache and operates at 3.5 GHz by default, but can boost up to 3.8 GHz, depending on the workload. AMD is making the Athlon X4 845 on a 28 nm production node using 3,100 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 Athlon X4 845, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency. With a TDP of 65 W, the Athlon X4 845 consumes typical power levels for a modern PC. AMD's processor supports DDR3 memory with adual-channel interface. The highest officially supported memory speed is 2133 MHz, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Athlon X4 845 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 Athlon X4 845, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
