4月中这篇聊CPU的推文应该是近期财富密码最多最密集的一篇文章了。从4月中开始聊到到现在: intel、澜起科技都已翻倍甚至涨的更多; arm接近翻倍; amd、深南电路、海光也都有几十个点的涨幅。 昨晚Arm创新高,4月中聊到Agentic AI时代Arm服务器cpu是会更受益,首先其技术架构和功能更符合agentic ai对cpu的需求,然后是包括英伟达在内的几大云厂商的cpu都用的是Arm架构。之前Arm的走势还可以但没这么强势,直到这两天几个催化事件: 1)先是陈立武再次把gpu和cpu的比例把到很高; 2)同时陈立武和老黄也都把CPU的TAM推到更高的体量; 3)然后英伟达vera CPU开始发货。 市场才反应过来arm是美股cpu御三家(intel、amd、arm)最被低估的,之前认知不够现在赶紧找补回来。 有时你会发现,正确的逻辑兑现也需要时间。 本条由@bitget_zh赞助,「Bitget 买美股:秒级入场,丝滑交易 」

Just some mobile shower thoughts around $XFAB and train of thought: 1. 800vdc $NVDA push look for GaN/SiC players / power semis. 2. $NVTS and other fabless/fab-lite beneficiaries of $NVDA push probably use foundry models 3. care more about Western supply chains over Asia, want to build up Western capabilities + Western premiums. 4 China has a lot of capacity, maybe risk into 2028, but again it’s building up Western supply chains 5. XFAB only high volume SiC foundry in America (others like $ON or Infineon are vertically integrated) 6. advanced 6in SiC, 8in GaN on Si, building out 8in GaN 7. Maybe likely they’re developing 8in SiC from CHIPS backing, just not public material 8. check SiC revenue -> 152% Y/Y growth okay. Probably something markets missed, since blended looks worse from automotive slump, that should come out recovery 9. $NVTS and others turns out to use $XFAB. $POWI cites $XFAB in filings, among others. 10. both are $NVDA power semi explicit partners, great exposure indicator to 800vdc power semi players. 11. US Dpt. of commerce cites $XFAB as only high volume SiC foundry in the US, $50M PMT 12. validation from US Gov about critical component in supply chains is amazing 13. EU CHIPS Act gives $XFAB $128M EU, for foundry (MEMS, AI, etc), okay turns out they’re critical MEMS player 14. So that’s validation from EU gov about critical component in supply chains, dual continent subsidies 15. So now we know $XFAB is a critical MEMS foundry so you get SiC capabilities, GaN development, and MEMS upside 16. they also got $47.6M EU funding for leading Silicon Photonics supply chain in EU. So that’s EU funding on multiple angles. 17. Turns out, I know all the players there from smartphotonics from $GFS deck. 18. $NVDA and $NOK are qualifying them for silicon photonics HVM. I think this is just a government backing angle for success in EU photonics so likely to succeed… kinda like how Us gov encourages everyone to use $INTC. 19. Okay chips act 2 is coming out next week… so they’ll probably get funding there or more revenue commitments 20. 1.28 p/b, now that’s probably just book cost? Likely coming out of $SOI type legacy drag cycle. 21. Did some modeling around actually replacement values, true replacement p/b cost likely ~.5/.7. 22. Getting business for free, while having upside from SiC near term into Silicon Photonics / GaN as main growth past H2 2027. Thoughts: derisked by p/b values + replacement value. maybe like 20% downside from macro. However, critical dual continent importance. So downside risk seems low, but upside is compelling. Lot of capex likely backstopped by upcoming chips act catalyst + national security concerns. Maybe 2.5-4x rerating seems possible/likely. Not a 10-20x, but recovery from depressed valuations from silicon photonics upside with SiC / GaN bridge. TLDR: likely trading lower than replacement value, dual continent subsidies likely subsidize capex. Gov grants shows importance to Western supply chains, photonics longer term upside, SiC/GaN demand likely near term upside and bridge. Don’t control any recent volatility, should shake out anyone not really confident in the thesis though. CHIPS act 2 from EU is coming up, $XFAB was listed in earlier blueprints for optical ecosystem, so should get a boost after that comes out as near term event catalysts. So now is the risk reward seems compelling, we’ll see if this is right or not
