FX-8320 Details

For desktop users seeking a cost-effective, multi-threaded processor with integrated graphics support, the AMD FX-8320 remains a notable option from a bygone era of high-performance computing. Launched in October 2012, this eight-core processor was part of AMD's FX lineup, designed to deliver strong multitasking capabilities at a time when multi-core performance was becoming increasingly important for productivity and gaming. Although now over a decade old, the FX-8320 continues to hold relevance in budget builds or legacy systems where modern hardware is not required. Built on the Vishera microarchitecture and fabricated by GlobalFoundries at a 32 nm process, the FX-8320 features 1.2 billion transistors and a die area of 315 mm².

It operates at a base frequency of 3.3 GHz, with a turbo frequency of up to 3.6 GHz, and includes an unlocked clock multiplier for easy overclocking. The processor supports dual-channel DDR3 memory up to 1600 MHz, with a maximum capacity of 32 GB and a memory bandwidth of 25.6 GB/s. It uses the FCLGA1155 socket, supports PCIe 2.0, and has a TDP of 125 W, indicating significant power consumption and the need for robust cooling. Despite lacking integrated graphics in its standard form, the FX-8320 can leverage integrated graphics when paired with compatible motherboards that include chipset-based graphics support.

The processor includes an L3 cache of 7.629 MiB and supports a wide range of instruction sets, including SSE, AVX, and AES-NI, enhancing its versatility in both general computing and encryption tasks. In benchmark testing, the FX-8320 achieves an Overall Score of 5211, placing it at #700 among 2060 processors, with a Singlecore Score of 5507 (#546) and a Multicore Score of 4766 (#890). While its single-core performance is competitive, particularly against some modern low-power processors, its multicore performance trails significantly behind current high-end CPUs. The FX-8320 is outperformed by several contemporary processors, including the Core i7-4710HQ and FX-9590, but remains faster than some lower-tier CPUs like the Xeon E3-1220 v6.

As of March 2026, the FX-8320 is best suited for retro computing, legacy system upgrades, or users with specific software requirements that benefit from its 8-core architecture. Its age and power demands make it unsuitable for modern high-performance applications, but its affordability and overclocking potential ensure it still holds niche appeal.
