This photo shows a NVIDIA Tesla A100 board. Please note the 4 SMD components on each side of the chip. Looks like gold plated ceramics. I have never seen components like this. Can someone identify this components?

    \$\begingroup\$ also, this, and all images on the site you link to are just 3D renderings, and might or might not look like the real device, at all. \$\endgroup\$ – Marcus Müller May 30 at 15:59

It seems like this is a Power-On-Package from Vicor.

They call these modular current multiplieres (MCM) and they are basically step down converters. They aim to drive these with their modular current drivers (MCD) with a voltage of up to 48V from the mainboard and step the voltage down only a few cm from the current hungry IC (that might draw up to 640A peak\$^1\$), to reduce power losses in PCB traces and socket pins.

On this page they say that NVidia uses these modules for the AI accelerators.
