The sizes of the transistors used in the CPU's circuits influence both power consumption and performance. Larger transistors enable better performance but consume more power and result in increased Vdd Full Scale Current. Designers need to strike a balance between performance requirements and power efficiency.

Power Delivery and Voltage Regulation

The power delivery subsystem, including the voltage regulator modules (VRMs), must be designed to meet the CPU's full-scale current requirements. Adequate power supply and well-regulated voltage levels are essential to ensure stable and reliable operation.

Thermal Dissipation

Efficient thermal dissipation mechanisms, such as heatsinks, heat pipes, and cooling fans, are critical to handle the increased power consumption resulting from high Vdd Full Scale Current. Cooling solutions must be designed to maintain the CPU's temperature within safe operating limits.

Voltage Regulator Modules (VRMs)

The VRMs responsible for converting the power supply's input voltage to the required voltage level for the CPU must be efficient and capable of delivering the necessary current. Inadequate VRMs can result in voltage droops or surges, impacting the CPU's stability and reliability.
