The announcement from Morgan Stanley about NVIDIA's Rubin GPU has caused significant reverberations across the technology sector, signaling a dramatic shift in the trajectory of graphics processing unit (GPU) development. The banking giant revealed that the highly anticipated Rubin GPU is entering its preparatory phase ahead of schedule, bringing its expected release from the first half of 2026 to the latter half of 2025. This advancement is not merely a testament to NVIDIA’s rapid progress in GPU technology but also signals fresh opportunities and challenges for the entire supply chain tied to its development.

In a report dated December 2, Morgan Stanley analyst Charlie Chan pointed out that while production for NVIDIA's current Blackwell chip is progressing steadily, the complexity of the Rubin GPU has prompted suppliers like Taiwan Semiconductor Manufacturing Company (TSMC) to begin preparing for its production earlier than initially expected. Rubin, a next-generation GPU, is expected to leverage a 3nm process—a significant upgrade over its predecessor. According to the report, this advanced 3nm Rubin GPU is projected to enter the taping phase in the latter half of 2025, creating a shift in the timeline that is welcomed by tech enthusiasts and industry stakeholders alike.

The Rubin GPU is expected to be a formidable competitor in the tech space, incorporating cutting-edge technologies like the 3nm process, Chip Package On Package (CPO), and High Bandwidth Memory 4 (HBM4). These elements will allow the Rubin GPU to significantly outperform its predecessors in multiple sectors, including high-performance computing, artificial intelligence (AI), and graphics rendering. The size of the Rubin chip, which could be up to twice the size of the Blackwell chip, will house four computation chips, a marked increase from Blackwell’s two-chip setup. This added complexity positions Rubin as a transformative force, capable of pushing industries into new realms of technological innovation.

As the supply chain prepares for the next steps, TSMC is also gearing up to expand its Chip on Wafer Substrate (CoWoS) capabilities in 2026 to accommodate the increased chip area of Rubin. This move underscores the company's readiness to scale production in response to the anticipated demand for more advanced technology, particularly in sectors like AI, where capital expenditures are expected to remain strong. TSMC plans to begin placing orders with equipment suppliers by mid-2025 to ensure production meets the anticipated needs. This foresight suggests the industry's capacity to adapt and thrive as demand for next-generation chips rises.

However, not all elements of the supply chain are moving as smoothly. Analysts have flagged a delay with ASMPT, the company responsible for providing Thermal Compression Bonding (TCB) tools, a key component in the CoW manufacturing process. TSMC has placed orders with K&S for non-solder TCB tools that align with the CoW process, but ASMPT has yet to complete its certification. While discussions regarding the certification are ongoing, Morgan Stanley remains optimistic that ASMPT will complete the necessary certification by the end of the year, paving the way for initial procurement of equipment in the second half of 2025. Although analysts predict that orders for non-solder TCB tools in 2025 will be limited, demand is expected to increase rapidly as Rubin enters large-scale production in 2026.

The introduction of a new GPU like Rubin creates opportunities not just in production but also in testing. Analysts at Morgan Stanley have pointed out a trend: the testing durations for Blackwell and other recent models, such as the MI355, have significantly lengthened. Blackwell, for instance, has required three times the testing time of its predecessor, Hopper, while MI355 has needed double the time. These increased testing requirements have stretched delivery timelines for testing equipment manufacturers such as Advantest, with wait times growing from the typical three months to six months. This shift highlights the importance of testing in the GPU production process, especially as the demand for high-performance chips continues to surge. The more intricate structure and higher performance capabilities of the Rubin GPU are expected to further extend testing times, presenting new opportunities for testing equipment manufacturers and service providers. As companies look to meet growing demand, they will need to invest in ramping up R&D efforts and production capacity to handle the increased workload.

The competition in the field of high-performance chips is not limited to NVIDIA’s Rubin GPU. Companies in the AI and semiconductor sectors are closely watching the development of specialized integrated circuits, such as AWS’s 3nm AI accelerator, which is moving through its research and testing phases. Insights from the supply chain suggest that TSMC will continue final testing for Blackwell at KYEC, with the dual-chip B200/300 version of Blackwell expected to ship around five million units by 2025, leveraging TSMC’s CoWoS-L capacity. This competitive atmosphere, fueled by continuous innovation, is driving the AI and high-performance computing market forward. As companies innovate and refine their products, the entire industry is seeing an increase in collaboration and competition, pushing for greater efficiency and sophistication.

The race to develop more powerful GPUs and AI hardware has also led to new technological collaborations. For instance, NVIDIA’s competitors, including companies like AMD and Intel, are intensifying their efforts to develop chips that can compete with the performance benchmarks set by Rubin. These companies are expanding their focus on artificial intelligence, machine learning, and high-performance computing as primary avenues for growth. Each company is seeking to carve out a niche in the rapidly evolving market, where the demand for faster, more efficient processing power is ever-growing. As a result, the sector is becoming increasingly interconnected, with companies relying on each other not just to push the boundaries of technology but to supply the necessary components that make these advancements possible.

As the GPU market heats up, the broader technological ecosystem is adapting to the changing landscape. Supply chains are evolving, partnerships are forming, and new challenges are emerging as the demand for high-performance computing reaches new heights. From the manufacturing process to testing and product delivery, each step is becoming more complex, requiring greater coordination and innovation. The emergence of Rubin GPU is not just about a single breakthrough in chip technology but represents a broader shift in the industry, one that will redefine the competitive dynamics in AI, gaming, and other technology sectors for years to come.

Looking ahead, the continued evolution of GPUs, particularly those integrated with AI capabilities like Rubin, signals a future where technological advancements are increasingly shaped by collaboration and competition. As the market for AI and high-performance computing expands, companies will need to continue refining their processes and technologies to keep up with the rapidly advancing landscape. Whether it is through faster manufacturing, better testing protocols, or more sophisticated chips, the future of GPUs promises to be as dynamic as it is transformative. In this environment, the stakes are high, and the race for innovation is only just beginning.
