The hue of a PCB (Printed Circuit Board) on graphics cards or motherboards does not directly correlate with hardware performance. Typically, entry-level products utilize green PCBs due to their cost-effectiveness, mature manufacturing process, and ease of production and repair. Conversely, high-end products opt for dark blue or black PCBs, primarily as a branding tactic to exude a premium aesthetic. Furthermore, these darker hues necessitate higher production standards, thereby showcasing the manufacturer's technical expertise. In essence, as long as the PCB employs the same base material and copper foil specifications, its signal transmission and electrical characteristics remain uniform. When selecting hardware, it is crucial to prioritize factors that inherently determine quality, such as material composition and design intricacies.
