雲端服務商自研晶片的擴張規模正在改寫伺服器供應鏈的版圖。最新產業研究預估，某指標雲端巨頭的張量處理器至 2027 年晶片總量將達到 800 萬至 900 萬顆，換算超過 10 萬個機櫃，年成長率突破 150%，其總量體已足以與主流圖形處理器加速器分庭抗禮。這個轉變意味著特殊應用晶片已從特定場景的輔助算力，晉升為資料中心擴建的同等核心支柱。當單一業者的自研晶片機櫃規模在 3 年內跨過 10 萬櫃門檻，現有代工製造網絡將徹底不敷使用，迫使訂單向外擴散，為台灣硬體組裝族群催生出全新的第 2 成長曲線。The aggressive ramp-up of custom in-house silicon by cloud service providers is redrawing the server supply chain map. The latest industry research estimates that total shipments of a leading cloud giant's Tensor Processing Unit will reach 8 million to 9 million units by 2027—equivalent to over 100,000 server racks—representing an annual growth rate exceeding 150%. This volume is now substantial enough to rival mainstream GPU accelerators. The shift marks the graduation of application-specific integrated circuits (ASICs) from niche workload coprocessors to co-equal pillars of data center buildouts. With a single operator's proprietary rack deployment crossing the 100,000-rack milestone within three years, existing contract manufacturing capacity will be overwhelmed, forcing orders to spill over and opening a fresh secondary growth curve for Taiwan's hardware assembly sector.

產能缺口迫使代工供應鏈向外擴張Capacity Shortfalls Force Assembly Supply Chains to Broaden

產能擴充的迫切性直接反映在代工體系的洗牌上。過去這家雲端業者的伺服器組裝主要集中於少數核心夥伴，但面對 2027 年倍數級跳升的機櫃需求，既有產能難以承載整體出貨排程。最新通路訪查顯示，已有另外 2 家台灣一線硬體大廠開始展開前置作業，預計於 2027 年正式切入該供應鏈。這對台灣硬體代工業具有劃時代意義，過往高度倚賴單一加速器龍頭架構的接單模式，將轉向由自研晶片與標準架構雙軌並行的格局。新客戶群不僅帶來更分散的營收結構，亦可能透過不同的客製化合約條件，重塑代工廠的毛利分佈。The urgency of capacity expansion is triggering a reshuffle across contract manufacturing networks. While this cloud giant previously concentrated its server assembly within a handful of core partners, existing lines cannot absorb the multi-fold surge in rack demand targeted for 2027. Recent channel checks indicate that two additional tier-one Taiwanese hardware heavyweights have commenced preparatory work, aiming to enter the vendor list in 2027. This marks a milestone for Taiwan's EMS sector: the historical model of relying heavily on a single dominant accelerator architecture is giving way to a dual-track dynamic spanning both in-house ASICs and standard GPU frameworks. A broader client base yields a more diversified revenue mix and, through tailored contract terms, can reshape manufacturers' margin profiles.

新舊平台接軌帶動第 4 季營收續揚Platform Transitions to Drive Fourth-Quarter Top-Line Momentum

在長線爆發前夕，近期的出貨節奏取決於新舊產品世代的切換過程。研究單位目前維持今年新一代機櫃出貨 2,000 櫃的基準預估，整體時程落在第 3 季末啟動小量試樣，並在第 4 季進入整櫃規模化量產。雖然在世代更替期間，既有架構機櫃的出貨量預料將在第 4 季出現小幅度的季減走勢，但由於新世代機櫃採用更複雜的電氣架構與散熱系統，使得單機櫃平均售價顯著拉升。在單價提升的乘數效應下，代工廠在第 4 季仍可順利抵銷舊款下滑的衝擊，維持營收季增動能，確立了獲利向上推進的實體支撐。Ahead of this long-term inflection, near-term delivery momentum hinges on the generational transition between product lines. Research institutions maintain their baseline projection of 2,000 next-generation rack shipments this year, with low-volume sampling commencing late in the third quarter followed by full-rack volume ramp-up in the fourth quarter. Although shipments of legacy-architecture racks are slated for a modest quarter-over-quarter dip during the transition, the next-generation systems feature significantly more complex electrical topologies and liquid cooling architectures, driving a sharp rise in average selling price per rack. Through this multiplier effect, assemblers are well-positioned to offset legacy declines, sustain sequential revenue growth in the fourth quarter, and reinforce forward earnings.

租賃價格調漲揭示算力供需真實張力Surging Cloud Rental Rates Reflect Underlying Compute Scarcity

探究這波硬體擴張背後的動能來源，終端算力市場的價格變化提供了最直接的印證。2 家新興雲端基礎設施業者在今年連續多次上調算力租賃價格，其最新專案合約的營業利益率，甚至高出歷史平均值達 5 至 20 個百分點。研調機制指出，這波價格上漲並非來自上游硬體採購成本的轉嫁，而是終端市場對高性能運算資源的實質供不應求。算力租金的走揚通常扮演著資本支出上修的先導指標，當雲端營運商能夠在終端維持強勁的定價能力與超額利潤，後續追加機櫃採購與擴大硬體投資的確定性便隨之大幅提高。The underlying strength of this hardware expansion is underscored by pricing dynamics in the computing power rental market. Two emerging cloud infrastructure providers have enacted multiple rate hikes for compute rentals this year, with operating margins on their latest deal signings beating historical averages by 5 to 20 percentage points. Market intelligence indicates these increases are not mere pass-throughs of higher hardware procurement costs, but rather reflect authentic demand outpacing high-performance compute supply. Rising rental rates historically serve as a leading indicator for upward capital expenditure revisions; as cloud operators command strong pricing power and generate surplus margins, the certainty behind subsequent rack orders and expanded hardware capex increases substantially.

本刊判斷，自研晶片生態系正在脫離驗證期、步入實質放量期，硬體代工評價模式將迎來重估。接下來的觀察重點在於第 4 季新平台量產的良率爬坡速度，以及算力租金漲勢是否從新興業者進一步擴散至大型超大規模資料中心，這將是判斷 2027 年 10 萬櫃擴編能否如期兌現的關鍵風向球。We judge that the proprietary ASIC ecosystem is graduating from the pilot verification phase into high-volume deployment, warranting a re-rating of hardware manufacturing valuations. Critical checkpoints going forward will be the production yield curve of the new platform in the fourth quarter and whether rental price inflation spreads from emerging players to the broader hyperscaler tier—a key barometer for whether the 100,000-rack expansion target for 2027 can be delivered on schedule.
