The present application relates to a chip heat dissipating structure, a chip structure, a circuit board and a supercomputing device, and the chip heat dissipating structure includes a plating layer covered on the chip, where the plating layer includes a first metal layer and a second metal layer arranged in sequence. By adding two metal layer on the top of the chip by physical sputtering, the heat sink may be soldered onto the metal layer through a solder layer, so that the heat sink is fixed to the top of the chip; the main component of the solder layer is metal tin, and the metal layer has a higher thermal conductivity than an epoxy resin material mounted on a traditional heat sink, thereby solving a problem of the heat dissipation bottleneck of a resin material in the chip, thus improving a heat dissipation effect of the chip.
