Quite interesting coverage of Nvidia's hardware choices:
"Instead of one big piece of silicon, Blackwell consists of two advanced new Nvidia processors and numerous memory components joined in a single, delicate mesh of silicon, metal and plastic.
The manufacturing of each chip has to be close to perfect: Serious defects in any one part can spell disaster, and with more components involved, there is a greater chance of that happening. What’s more, the heat generated by all those pieces risks warping different materials in the package at different rates."
