Blackwell GPU reportedly takes 3X to 4X longer to test than Hopper — more complex designs lead to skyrocketing test requirements
This drives demand for Advantest machines.
Nvidia's Blackwell GPUs are some of the most complex semiconductor devices ever built, significantly increasing their manufacturing, packaging, and testing difficulty. Since Blackwell involves two highly complex chiplets with new features and higher thermals, it is natural that testing them takes more than twice as long. In general, Blackwell's long test time reflects the growing complexity of these AI and HPC GPUs and the requirement for extensive validation to ensure performance and reliability in various data center environments when functioning alongside other components, such as CPUs, DPUs, and network interface cards.
