Yesterday I wrote already on bottleneck bs (see comment section belowh it is even worse after @jukan05 post. It has nothing to do with Jukan but the accounts quoting him. Makes visiting X also a bit tiring sometimes. Yeah, so NVIDIA is reportedly visiting Korean power equipment makers about 800V DC architecture. And immediately the timeline is framing power chips as "the new photonics." That framing isn't analysis it's engagement bait. Photonics went parabolic, so slapping that label on the next “thing” gets clicks and followers. For example liquid cooling is crucial for Rubin and beyond going into 800v DC. Switchgear and transformers are a real grid bottleneck right now. They have the right bottleneck framing. GE Vernova, Hitachi energy etc. Busbars and PDUs? Eaton, Schneider. $ETN $SU.PA all are critical data center components. None of them got the "new photonics" treatment. Why? Because they didn't 10x in 12 months. That's the only criteria they use for their engagement both Eaton and Schneider are literally NVIDIA ecosystem partners with co-developed reference designs, and Schneider is effectively embedded in the Blackwell rollout. If “NVIDIA visiting Korean power makers” = “new photonics,” then Schneider co-designing NVIDIA’s liquid-cooled reference architecture should’ve been “the new photonics” two years ago. It wasn’t. Because it didn’t 10x. 800V DC is a real shift don’t get me wrong but it’s in works already for 2 years. $NVTS and the legacy power names have been building toward this for a while. Keep that in mind. But the "new photonics" frame tells you nothing about the technology. It tells you what someone needs you to believe to follow their account. I wrote a 2 part AI power transition thesis last year covering begin state build-out market all the way to end-state (when the vast majority is build-out) to give you a understanding how you reverse engineer a whole build-out. You can read it on our SS link in bio.
