🧠 CoWoS Enters the Server CPU Arena!
What The Chip: TSMC revealed during its Q4 2024 earnings call that its CoWoS (Chip-on-Wafer-on-Substrate) packaging technology—previously focused on AI and GPU applications—will soon grow in server CPUs, marking a significant expansion of its application scope.
Details:
🔄 Broadening CoWoS Usage: TSMC’s CEO, C.C. Wei, confirmed that while CoWoS is currently AI-centric, server CPUs will soon adopt this advanced packaging solution, signaling new opportunities for high-performance computing markets.
⭐ AI-Driven Demand: CoWoS capacity remains tight due to overwhelming AI-related demand. Wei hinted at expanding capacity to serve broader applications, including servers.
📊 Performance Gains: CoWoS enables higher memory bandwidth, reduced latency, and better power efficiency—critical features for server CPUs tackling AI, cloud computing, and HPC workloads.
✉️ Quotes from Management: Wei stated, “On the CPU and server chip, let me give you a hint. It’s coming.” This underscores TSMC’s confidence in CoWoS’s potential beyond GPUs.
🚫 Challenges Ahead: Advanced packaging solutions like CoWoS come with high costs and manufacturing complexity, potentially slowing widespread adoption. The heavy demand from AI GPUs/Accelerators can also add to the complexity of mass-producing a CPU using CoWoS.
🌐 CoWoS On CPUs?: Fujitsu’s A64FX and Intel’s Sapphire Rapids MAX CPUs have integrated HBM using different packaging (similar to CoWoS); TSMC’s move into server CPUs highlights new market opportunities. In October, we learned that Microsoft and AMD have worked together to develop a custom 4th Generation EPYC processor with high bandwidth memory (HBM).
🌐 Expanding Applications: CoWoS technology could reshape server architectures, allowing CPUs to incorporate AI accelerators and larger memory caches directly on the package.
Why AI/Semiconductor Investors Should Care: This marks a pivotal moment for TSMC as it expands CoWoS beyond GPUs into server CPUs. For investors, it signals TSMC’s strategic focus on capturing broader market segments within high-performance computing. As AI workloads diversify, CoWoS’s enhanced integration capabilities could create new revenue streams while maintaining its leadership in advanced packaging solutions.

Arm Holdings (NASDAQ: ARM)
📈 Arm's Price Hike Could Threaten Samsung’s Exynos Chips!
What The Chip: Arm reportedly plans to increase its licensing prices by up to 300%, a move that could heavily impact Samsung’s Exynos chips. This price hike comes at a challenging time for Samsung, which faces struggles with its 3nm process yield and Exynos’s declining market presence.
Details:
🔄 Significant Price Increase: Arm’s reported 300% price hike targets its CPU core licensing, which could drastically raise costs for companies like Samsung that depend heavily on ready-made Arm CPU cores.
🔷 Exynos Struggles: Samsung’s low 3nm yield rates have already forced its flagship Galaxy S25 to forgo Exynos chips in favor of Qualcomm’s Snapdragon processors, compounding challenges for its chip division.
⚡️ Custom Core Disadvantage: Samsung’s decision to abandon in-house CPU core development has left it dependent on Arm’s solutions, making it more vulnerable to pricing changes.
🚫 Potential Cost Implications: Higher costs for Arm cores could make Samsung’s Exynos processors less competitive in pricing and performance against Qualcomm and MediaTek.
📊 Market Ramifications: With Exynos already lagging in adoption by Android OEMs, further cost pressures might force Samsung’s MX division to pivot entirely to Snapdragon processors for its premium smartphones.
Why AI/Semiconductor Investors Should Care: Arm’s reported pricing strategy highlights its effort to capitalize on its dominant position in semiconductor IP. While this could boost Arm’s revenues, it risks alienating major partners like Samsung, potentially reshaping alliances in the smartphone processor market. Investors should watch how this pricing strategy impacts licensing adoption and whether Samsung can mitigate these challenges to maintain competitiveness.
Taiwan Semiconductor Manufacturing Co. (NYSE: TSM)
🌀 Earthquake Hits Taiwan, TSMC Responds with Resilience!
What The Chip: A 6.4 magnitude earthquake struck Southern Taiwan, prompting TSMC to evacuate its central and southern facilities as a precaution. Early reports suggest no significant damage to equipment, but stock volatility may follow as recovery efforts are assessed.
Details:
🔄 Safety Measures in Place: TSMC evacuated staff from affected fabs, including Fab18, a critical site for 3nm production, ensuring employee safety as the first priority.
⚡️ Limited Equipment Impact: According to reports, TSMC’s fabs are equipped with anti-vibration systems, minimizing the risk of major damage. Some equipment may require recalibration.
⚙️ Production Recovery Efforts: Engineers and supply chain partners are actively working to restore operations. Early recovery activities suggest downtime will be temporary.
📈 Short-Term Volatility Expected: Historical precedents show that while earthquakes can cause immediate stock fluctuations, long-term performance remains unaffected if equipment is not significantly damaged.
🔄 Resilience Highlighted: TSMC has weathered similar events before, showcasing robust disaster recovery capabilities and minimal disruption to its long-term growth trajectory.
Why AI/Semiconductor Investors Should Care: While this event may introduce short-term uncertainty, TSMC’s history of resilience in similar situations suggests no long-term impact on its strategic growth. Investors should monitor updates but view this as a temporary disruption rather than a major concern for TSMC’s advanced manufacturing leadership.
