The AMD FX-4120 is a desktop processor with 4 cores, launched in October 2012. It is part of the FX lineup, using the Zambezi architecture with Socket AM3+. FX-4120 has 8 MB of L3 cache and operates at 3.9 GHz by default, but can boost up to 4.1 GHz, depending on the workload. AMD is building the FX-4120 on a 32 nm production process using 1,200 million transistors. You may freely adjust the unlocked multiplier on FX-4120, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 95 W, the FX-4120 consumes a good deal of power, so decent cooling is needed. AMD's processor supports DDR3 memory with a dual-channel interface. For communication with other components in the system, FX-4120 uses a PCI-Express Gen 2 connection. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability.
Hardware virtualization is available on the FX-4120, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
