Whatever the 'problem' actually was...

I picked that illustration because it shows the 'problem' -- DC in, heat out. Here's a more indepth description: semianalysis.substack.com/p/tesla-dojo-unique-packaging-and-chip

The description around that illustration:

The power delivery is unique, custom, and extremely impressive as well. With so much bandwidth and over 10KW of power consumption on the package, Tesla innovated on power delivery and feeds it vertically. The custom voltage regulator modulator is reflowed directly onto the fan out wafer. Power, thermal, and mechanical are all interfacing directly with the tile.

It appears the total tile is 15KW of power even if the chips themselves are only 10KW total. Power delivery, IO, and wafer wires are drawing a ton of power as well. Power comes in from the bottom while the heat comes out the top. Chips are not the unit of scale for Tesla, the 25 chip tiles are. This tile far surpasses anything from Nvidia, Graphcore, Cerebras, Groq, Tenstorrent, SambaNova, or any other AI training geared start up in per unit performance and scale up capabilities.
