Hello,
I wonder, as the voltages seem to be set to drop by at least 0.1-0.2 volts before copper losses will start becoming hard blockers, is FIVR, or another on package/on chip switching DC-DC a must to continue scaling?
What do you people think of Vicor transformators that Nvidia uses on high end cards?
