That's why the ROG Maximus Z790 Apex Encore utilizes teamed power stages to deliver higher burst current per phase, while maintaining the thermal performance of phase-doubled designs.Įach VRM component serves a specific purpose. These improvements necessitate a re-evaluation of power-design priorities because phase-doublers add a propagation delay that hampers transient response.įortunately, the latest integrated power components can handle higher currents than the devices of yesteryear, making it possible to implement a simple circuit topology that isn't hamstrung by the processing lag of phase-doublers.
In addition, they consume less power at idle and can transition between load states much more quickly. Modern CPUs pack more cores than their predecessors, and the latest instruction sets allow them to crunch computationally dense workloads at an incredible pace. Those benefits led to phase-doublers becoming universally accepted in the industry, and they are still used for similar purposes today.
The board's VRM was lauded for elegantly overcoming the power handling capabilities of components that were available at the time while also reducing voltage ripple.
ASUS became the first manufacturer to implement phase-doublers with the A8N32-SLI Deluxe motherboard, back in 2005.
