The advancement of Nvidia’s Blackwell GPUs has pushed the boundaries of semiconductor technology. These cutting-edge devices entail a dramatically intricate manufacturing process, presenting significant challenges in terms of packaging and testing. According to insights shared by Doug Lefever, CEO of Advantest, the testing duration for Blackwell GPUs is significantly more extensive compared to the previous Hopper series.
Packed with unprecedented complexity, the Blackwell family includes the B100 and B200 models, which are built with two compute chiplets that integrate a staggering 104 billion transistors. In comparison, the Hopper H100 model is constructed with a single chiplet featuring 80 billion transistors. As the transistor count rises, so does the complexity of testing, escalating almost exponentially due to the need for more elaborate test patterns.
Each Blackwell GPU demands a rigorous testing regimen, scrutinizing high-speed interconnections, thermal conditions, and various operational modes, including the new FP4 support. This heightened scrutiny is a natural consequence of the advanced capabilities and increased thermal output associated with the Blackwell GPUs.
The adoption of TSMC’s CoWoS-L packaging technology further complicates the testing procedures, adding more phases and steps to ensure the performance and reliability of every component. With extensive verification required for both compute and memory chiplets, the Blackwell testing process stands as a testament to Nvidia’s commitment to producing robust, high-performance hardware for data centers that meet modern demands.
