Anastasi in Tech - What’s with the new Nvidia GPU?

One of the video’s first statements “Why is TSMC having trouble manufacturing it?”

(Some good discussion in here about CoWoS-L vs CoWoS-S also)

Her explanation seems to indicate the total wattage translates to a lot of heat, which causes thermal expansion issues at the substrate level causing connections to move around / disconnect. She contrasts this with the previous gen having the same issues but less overall size / heat / etc to worry about.

More specifically, the new Cowos version using silicon bridges embedded in a poly/organic substrate is implicated, whereas the previous silicon interposer was more robust. It's all speculative.
