Nvidia Rubin is the new architecture named after Vera Florence Cooper Rubin, a pioneering astronomer who first established the presence of dark matter. During the presentation, architectures following Blackwell were also mentioned - Blackwell Ultra, Rubin, Rubin Ultra, and Vera. It's worth noting that the last codename does not refer to a GPU architecture but rather a CPU.
The GPU Rubin will support 8-Hi HBM4 stacks, while subsequent GPUs after it, namely the Rubin Ultra, will support 12-Hi HBM4 stacks. NVIDIA confirmed that the initial models of the Rubin GPUs will include 8 stacks of HBM4 memory, and the enhanced version, Rubin Ultra, will include 12 stacks of HBM4, significantly increasing memory capabilities and overall performance.

At the conference, it was also noted that the bandwidth of Nvidia's patented NVLink interconnect technology will be doubled to 3.6 Tbps. Nvidia also announced plans to update Grace - their processor for the GR200 Superchip module, which will contain two R100 GPUs and an updated Grace CPU based on the 3nm TSMC technology process. Currently, the Grace processor is built on the 5nm TSMC process and contains 72 cores, totaling 144 cores in the Grace Superchip.

It was particularly emphasized that one of the main directions for Nvidia with the next-generation graphics processors Rubin R100 will be energy efficiency. Nvidia is aware of the growing power consumption needs of its chips for data centers and promises significant improvements in this area, while also enhancing the capabilities of its chips in the field of artificial intelligence.

To address AI tasks and support other resource-intensive applications, servers with x86 and Arm architecture CPUs, equipped with both air and liquid cooling systems, will be released. Customers will have access to models with both single and multiple accelerators. NVIDIA itself offers the Blackwell DGX systems, while third-party manufacturers offer ready-made platforms like HGX B100 and HGX B200.
It has also been revealed that the company has struck deals with MSI and Asus, who will release PCs featuring Nvidia GeForce RTX graphics processors for AI functions, including virtual assistants, video editing, and programming.
