AI server assembler Wiwynn’s recent 4Q25 gross margin miss (7.2% vs. consensus estimates of 8–8.3%) has triggered a share price correction and reignited investor concerns. While rising component costs can mechanically dilute reported gross margins, it is more critical to examine the underlying profitability trends in server assembly through the lens of structural changes in AI server design.Nvidia continues to increase the level of design integration in AI servers to boost token output per unit of space and ...

近期AI伺服器組裝廠商緯穎公布低於預期的4Q25毛利率 (7.2% vs. 市場預期的8-8.3%)，導致股價下跌，此事又引起投資人關注。雖零組件漲價也會稀釋帳面上的毛利率，但更重要的是從AI伺服器設計的本質上去檢視組裝的獲利能力趨勢。Nvidia持續提升AI伺服器的設計整合程度，以提升每單位空間與電力的Token產出，來因應資料中心有限空間與稀缺電力挑戰。此外，高度整合的設計也有助於改善生產效率，進而有利供應鏈管理與降低維修成本。VR200 NVL72就是設計高度整合的例子，我的產業調查顯示，其Compute tray導入無線化設計（Cable-less），零組件項目顯著減少約40% (vs. GB300 NVL72)。但隨整合程度提高，伴隨而來的是Nvidia指定用料比重提升，與客製化空間也遭到壓縮，這些都不利組裝廠商的獲利能力。我的產業調查顯示，VR200 NVL72 compute tray「不允許客製化規格」的零組件項目佔比提升至20-22%，遠高於GB300 NVL72的5-7%，且VR200 NVL72更直接取消「ODM設計」的零組件項目。事實上，提高整合程度的設計趨勢自GB300 NVL72就 ...

Regarding recent discussions among CCL-focused investors on whether the key CCL spec for VR200 NVL72 could be downgraded from M9, below are my latest surveys and views:1. Nvidia previously began testing 896K2 and 892K2 and prototyping PCBs, which likely gave rise to the market rumors. Test results are expected by the end of 1Q26.2.Nvidia’s current mass-production target remains 896K3. While this has not been finalized, the uncertainty alone is sufficient to impact stock prices that have already priced in th ...

Key Updates on NVIDIA Vera Rubin/VR200 NVL72(Integrating my latest supply chain checks and NVIDIA CEO Jensen Huang’s CES 2026 keynote)1. NVIDIA has renamed the AI server VR200 NVL144 (die-based) to VR200 NVL72 (package-based). My supply chain checks indicate VR200 NVL72 will be offered in two power profiles: Max Q and Max P.➢ Jensen referenced NVL72, rather than the previously used NVL144 naming.➢ Max Q and Max P share the same hardware design.➢ Max Q GPU/rack power (TGP/TDP): ~1.8/190 (kW).➢ Max P GPU/rack ...

Nvidia Vera Rubin/VR200 NVL72重點更新，整合我的最新產業調查與Nvidia CEO黃仁勳的2026 CES演講1. Nvidia將AI伺服器VR200 NVL144 (die-based) 改名為VR200 NVL72 (package-based)。我的調查指出，VR200 NVL72將分為Max Q與Max P兩種power profile。➢ 黃仁勳提到了NVL72，而非先前的NVL144➢ Max Q與Max P硬體設計相同➢ Max Q GPU/機櫃功耗 (TGP/TDP)：約1.8/190 (kW)➢ Max P GPU/機櫃功耗 (TGP/TDP)：約2.3/230 (kW)➢ 兩者均顯著高於GB300 NVL72的1.4/140 (kW)➢ 因應資料中心供電規格，不同power profile提升安裝彈性。此改變也意味著Nvidia開始注意到物理世界對建置AI伺服器的限制，並將其反映在產品規格上2. VR200 NVL72 Max Q與Max P的GPU散熱設計升級。➢ 兩者均採用微通道冷板 (micro-channel cold plate；MCCP) 搭配鍍金散 ...
