Abstract
Methods and apparatus relating to low-overhead utilization-aware link-width modulation to reduce power consumption in interconnects are described. In one embodiment, a link width modulation logic adjusts the width of an interconnect link. More particularly, the link width modulation logic causes the interconnect link to transition from a first width to a second width based on comparison of a utilization value associated with the interconnect link against at least one of a plurality of utilization threshold values. Other embodiments are also disclosed and claimed.
