AMD FD8370FRHKBOX FX-8370 Black Edition CPU

The AMD FX-8370 Black Edition is the performance peak of AMD's AM3+ Piledriver platform — an eight-module processor clocked at 4.3GHz base with a 16MB combined cache (8MB L3 shared, 8MB L2 distributed across four modules) and a 125W TDP. Understanding the architecture is essential to understanding the benchmark numbers: the FX-8370 uses a module design in which two integer clusters share a floating-point unit and front-end resources. This means eight "cores" in a workload scheduler's view, but with meaningful resource sharing under mixed instruction workloads. In practice, the FX-8370 is most competitive in heavily threaded, integer-dominant workloads — video encoding, file compression, and multi-threaded compilation — where its eight threads and high clock rate can distribute load effectively.

The Black Edition designation signals the unlocked multiplier, which is the FX-8370's most practical differentiator from locked FX variants. On a capable 990FX or 970 chipset motherboard with a 120mm+ liquid or high-performance air cooler, the chip typically achieves stable overclocks in the 4.5–4.7GHz range with moderate voltage increases. This is a processor for budget-conscious builders or existing AM3+ platform owners who want maximum threaded throughput without a full system rebuild — system integrators, home media encoding rigs, and workstation users on tight budgets who can manage the thermal envelope. For anyone building a new platform today, the AM3+ socket's DDR3 limitation and lack of PCIe 3.0 support make it a legacy choice; for existing AM3+ systems, the FX-8370 represents the platform ceiling.
