Nvidia Will Still Dominate 2027 TSMC CoWoS Demand, with Google TPU and AMD CPUs Providing Incremental Upside
Morgan Stanley expects global CoWoS demand to grow 93% YoY to 2.694 million wafers in 2027, with Nvidia remaining the largest user, MediaTek and Broadcom benefiting from Google TPU expansion, and AMD Venice CPU demand also expanding significantly.
- TSMC’s assumed CoWoS capacity at end-2027 is raised from 170k wafers/month to 200k wafers/month, reflecting strong AI GPU and CPU demand.
- Nvidia’s total 2027 CoWoS consumption is expected to grow 57% YoY to 1.222 million wafers, of which CoWoS-L accounts for about 910k wafers, mainly for Blackwell, Rubin, and Rubin Ultra.
- MediaTek has booked 180k CoWoS-S wafers for Google TPU v8t ZebraFish, corresponding to about 3.6 million TPUs; if ABF substrate supply improves, there is upside to the shipment assumption.
- AMD’s total 2027 CoWoS consumption is expected to grow 308% YoY to 530k wafers; Venice CPU bookings rise from 50k wafers in 2026 to 270k wafers in 2027, implying about 6.75 million CPUs.
- The report reiterates a positive view on TSMC, ASE, KYEC, Winway, MPI, and Hon Precision in the AI semiconductor supply chain, and keeps MediaTek as the top pick.
Report interpretation
Overview
This report centers on the allocation of TSMC and global CoWoS advanced packaging capacity in 2027, with a focus on demand changes from customers such as Nvidia, Broadcom, AMD, MediaTek, AWS/Annapurna, Marvell, and GUC. The report argues that Nvidia’s AI GPU and Vera CPU remain the core drivers of TSMC CoWoS demand, while Google TPU and AMD Venice CPU become important incremental sources in 2027.
Core views
The key judgments are as follows: first, Nvidia may still be the largest TSMC CoWoS user in 2027, with total consumption expected to reach 1.222 million wafers, up 57% YoY; second, Google TPU demand benefits both the Broadcom and MediaTek design-service chains, and MediaTek’s TPU v8t ZebraFish booking volume may be higher than current shipment assumptions; third, CPUs are beginning to consume 2.5D advanced packaging capacity meaningfully, with both Nvidia’s Vera CPU and AMD’s Venice CPU reflecting the expansion of agentic AI server demand; fourth, non-TSMC players such as ASE/SPIL and Amkor will also expand CoWoS-L and CoWoS-R capacity.
Analysis framework
The report combines supply-chain research, customer CoWoS booking decomposition, chip-to-wafer conversion, HBM capacity estimation, and wafer revenue TAM estimation. It first estimates the 2027 CoWoS demand of each AI chip vendor, then derives implied chip shipments, HBM consumption, and advanced-node wafer revenue scale.
Methodology notes
Split CoWoS bookings by customer, packaging type, and foundry/OSAT provider
The report divides CoWoS demand into CoWoS-L, CoWoS-S, and CoWoS-R, and distinguishes capacity sources such as TSMC, ASE/SPIL, and Amkor to assess the extent to which different customers and supply-chain links benefit.
Derive chip shipments from CoWoS wafer allocations
Based on the number of chips that can be carried by each CoWoS wafer, the report estimates the implied shipment scale of products such as Nvidia Rubin, Vera CPU, AMD MI series, Venice CPU, Google TPU, and AWS Trainium 3.
Derive HBM demand and wafer revenue TAM from AI chip shipments
The report further uses assumptions on HBM capacity, HBM die count, process node geometry, chip area, and wafer pricing to estimate 2027 AI HBM demand and the AI wafer revenue market size.

Impact & implications
In investment terms, advanced packaging is shifting from an AI GPU bottleneck into a key resource contested by GPUs, CPUs, and ASICs. Nvidia remains the largest source of demand, but Google TPU, AMD Venice CPU, AWS Trainium, Microsoft Maia, and Meta MTIA ASIC/CPU projects expand the demand base, benefiting TSMC, ASE/SPIL, Amkor, and other packaging capacity providers, as well as MediaTek, Broadcom, Alchip, GUC, and other AI ASIC design-service chains. The report is broadly positive on Taiwan’s AI semiconductor supply chain, with particular emphasis on MediaTek’s upside in Google TPU.
Risks
- CoWoS capacity expansion or yield ramp-up may fall short of expectations, preventing 2027 customer allocations from being realized.
- ABF substrates, T-Glass, HBM, or advanced-node wafer supply may be insufficient, limiting actual TPU, GPU, and CPU shipments.
- AI cloud capex or inference demand may come in below expectations, weakening advanced packaging demand from Nvidia, Google, AMD, AWS, and others.
- U.S. executive orders, export controls, and geopolitical restrictions may affect related securities trading, supply-chain shipments, and customer orders.
- The 2027e figures in the report rely heavily on supply-chain research and booking assumptions; if customer roadmaps or foundry/OSAT allocation changes, the estimates may deviate.
What to watch
- Whether TSMC’s CoWoS capacity reaches the assumed 200k wafers/month by end-2027.
- The production ramp of Nvidia Rubin, Rubin Ultra, and Vera CPU, and actual CoWoS-L/CoWoS-R consumption.
- Whether MediaTek can secure more T-Glass and ABF substrate supply for Google TPU v8t, allowing shipment assumptions to be revised upward.
- The extent to which AMD Venice CPU shipments rise from about 1.25 million in 2026 to about 6.75 million in 2027.
- Changes in share between Broadcom’s TPU v8i SunFish and MediaTek’s TPU v8t ZebraFish in the Google TPU ecosystem.
- Qualification and capacity expansion progress for CoWoS-L and CoWoS-R among non-TSMC players such as ASE/SPIL and Amkor.
- Whether 2027 AI HBM demand approaches 50,609mn Gb, and the supply capabilities of HBM vendors Hynix, Micron, and Samsung.
