Ohh neat! A generalized version of this was the topic of my PhD dissertation:

And they are likely doing something similar to put their LLMs in silicon. I would believe a 10x electricity boost along with it being much faster.

The idea is that you can create a sea of generalized standard cells and it makes for a gate array at the manufacturing layer. This was also done 20 or so years ago, it was called a "structured ASIC".

I'd be curious to see if they use the LUT design of traditional structured ASICs or figured what what I did: you can use standard cells to do the same thing and use regular tools/PDKs to make it.
