Nvidia unveils Rubin superchip titan
Nvidia displayed its Vera Rubin Superchip at the GTC conference in Washington on Thursday, marking the first public demonstration of hardware combining Vera processors with dual Rubin graphics chips. Chief Executive Jensen Huang said initial Rubin samples have arrived at the company laboratories from TSMC’s Taiwan facilities, and mass production should begin in late 2026.
The NVL144 system pairs 88-core Vera processors with Rubin graphics chips capable of 50 petaflops of FP4 performance and 288 gigabytes of HBM4 memory. The platform delivers 3.6 exaflops for inference and 1.2 exaflops for training, representing a 3.3x increase over current GB300 systems.
A more powerful Rubin Ultra variant will arrive in late 2027 with four reticle-sized chips per graphics processor. The NVL576 configuration will deliver 15 exaflops of inference performance and 5 exaflops of training performance, providing 14 times the power of existing GB300 hardware.
