The CPU socket looks special with it’s anodized black touch, and is physically different at the pins.
A 300% more gold content is added to the pins to improve electrical characteristics and lower the impedance and resistance of current flow from pin to CPU. From the first step of the input current to the last stage before the current flows into the CPU, the path seems to be made wider.
We move a little right:
An Inductor/Capacitor pair right next to the CPU for the Memory Controller gives a neighbor reservoir. As current has to flow past the DIMM slots from a further source, an Inductor here can help transient electrical behaviour.
