During NVIDIA’s conference, where they showed record financial results that were better than expected (despite a 7% drop in the stock market after the data was released), the company also revealed some details about its immediate future.
That future lies in new architecture Blackwell And in addition to showing performance data on its AI server versions with up to 4 times more power than the H100 Hopper, NVIDIA also revealed that they had been having trouble getting a yield -number of viable GPUs per wafer manufactured- high in manufacturing, but that They had already solved them in order to increase the production of their GPUs new generation in the last quarter of the year, the B100 and B200.
The solution that has allowed them to improve the yield in the manufacturing of these GPUs has been to change the lithography masks that they use in the manufacturing process at TSMC facilities. The problem was in the packaging phase of the chips, specifically in the joints between the GPU, LSI and Interposer blocks. Apparently, the coefficient of thermal expansion had been miscalculated of the materials that caused the base to warp and render the chip unusable. By redesigning the masks of the layers and protrusions of the silicon, it was possible to solve this and improve production performance.
The company expects to generate “billions of dollars” from sales of its Blackwell B100 and B200 GPUs for AI servers.
