Nvidia recently revealed details about its new AI graphics processors, and one of them is named for a scientist familiar to many space fans. Vera Rubin, the namesake for one of Nvidia's new AI GPU platforms, was the American scientist credited with discovering dark matter early in her career.

Nvidia will also offer a single rack called the GB300 NVL72 that offers 1.1 exaflops of FP4, 20TB of HBM memory, 40TB of “fast memory,” and 130TB/sec of NVLink bandwidth and 14.4 TB/sec networking.

The centerpiece announcement was Vera Rubin, first teased at Computex 2024 and now scheduled for release in the second half of 2026. This GPU, named after a famous astronomer, will feature tens of terabytes of memory and comes with a custom Nvidia-designed CPU called Vera.
