NVIDIA Rubin+Groq Hits $1T GPU Projection

🔑 Enhanced Key Takeaways

• •NVIDIA Vera CPU features 88 custom Olympus Arm cores with spatial multi-threading supporting up to 176 threads, paired with up to 1.5TB LPDDR5X SOCAMM memory at 1.2 TB/s bandwidth[1][2][3].
• •Vera Rubin NVL72 rack integrates 72 Rubin GPUs and 36 Vera CPUs, delivering 3.6 exaFLOPS NVFP4 inference, 54TB LPDDR5X, 20.7TB HBM4, and 1.6 PB/s HBM4 bandwidth[1][2][3].
• •Rubin GPUs provide 35 PFLOPS NVFP4 training performance (3.5x Blackwell), enable 1/4 the GPUs for MoE model training, and reduce MoE inference cost per token by up to 10x[2][3].
• •Rubin CPX GPU variant uses monolithic die with 128GB GDDR7 memory, 30 PFLOPS NVFP4 compute, and 3x faster attention for million-token contexts in NVL144 CPX platform[4].

🛠️ Technical Deep Dive

• •Rubin GPU is dual-die on TSMC 3nm with reticle-sized dies, eight HBM4 stacks for 22 TB/s bandwidth (2.8x Blackwell HBM3e), supporting third-generation Transformer Engine with NVFP4/NVFP8[1][3].
• •Vera CPU connects to Rubin GPUs via NVLink C2C gen2 at 1.8 TB/s coherent bandwidth, forming unified memory pool with HBM4 and LPDDR5X for KV cache and model weights[2][3].
• •NVLink 6 provides 3.6 TB/s GPU-to-GPU and 260 TB/s rack bandwidth; Rubin supports SMT with 176 threads and 2x data/compression performance over Grace CPU[1][3].
• •Rubin CPX optimizes inference with NVFP4 resources, 100TB fast memory, and 1.7 PB/s bandwidth in NVL144, offering 7.5x performance over GB300 NVL72[4].
