  "account": "Nvidia is reportedly experimenting with lower memory configurations for its upcoming Rubin Ultra accelerator due to ongoing global memory shortages. According to The Information, prototypes of the accelerator are being tested with as little as 192 GB of memory and even with HBM4 instead of the originally announced HBM4E. This comes after SemiAnalysis previously commented on the possibility of a memory downgrade for Rubin Ultra. The company has reportedly tested versions with 192 GB and 256 GB of memory, as well as fewer than the announced 16 memory stacks, and is also exploring the use of HBM4. The reduced memory configurations may be a strategic move by Nvidia to cope with the memory supply challenges that are impacting various AI data centers worldwide. Despite the memory setbacks, Nvidia remains committed to its roadmap, with the Rubin Ultra expected to launch in 2027. The company has partnerships with SK Hynix for next-generation memory technology, including HBM, LPDDR5X, and DDR5.",
  "summary": "Nvidia is reportedly testing at least three Rubin Ultra configurations that pack as little as 192 GB of memory, as opposed to the 1 TB of HBM4E originally announced.",
