Nvidia Rubin Kicks Off M10 Testing

🔑 Enhanced Key Takeaways

• •Rubin GPU features two reticle-size compute dies on TSMC 3nm process with two I/O tiles, delivering 50 PFLOPs of dense FP4 compute using 224 Streaming Multiprocessors and fifth-generation Tensor Cores[1][3][5].
• •Rubin Ultra configuration includes 16 stacks of HBM4E (1024GB capacity) and a row of four reticle-sized GPUs with two I/O chiplets, achieving 100 PFLOPs FP4 and 3600W TDP[1][2][7].
• •Rubin platform introduces NVIDIA Vera 88-core Arm-compatible CPU with 1.5TB LPDDR per CPU, NVLink 6 at 3.6TB/s bidirectional, and Kyber rack architecture for enhanced scale-up[1][3][4].
