Nvidia Windows PC SoC 競爭

🔑 增強重點摘要

• •GB10 SoC uses TSMC 3nm-class process node for both CPU and GPU chiplets, interconnected via NVLink-C2C for coherent memory sharing[1][3].
• •GB10 GPU includes 24MB L2 cache with 600GB/s aggregate bandwidth despite LPDDR5X memory limitation of ~273 GB/s[3][4][5].
• •N1X variant of GB10 features scaled-down 48-core iGPU with NPU targeting up to 1,000 TOPS FP4 for improved power efficiency in laptops[6].

🛠️ 技術深入

• •CPU tile: MediaTek-designed big.LITTLE with 10 Arm Cortex-X925 big cores and 10 Cortex-A725 little cores[1].
• •GPU tile: Blackwell architecture with latest CUDA cores, 5th-gen Tensor Cores, 24MB L2 graphics cache[1][3][5].
• •Interconnect: NVLink-C2C for chip-to-chip coherence; unified 128GB LPDDR5X memory (~273 GB/s bandwidth)[1][3][4].
• •Networking: Integrated ConnectX-7 at 200 Gbps via QSFP ports[1][3].
• •Process: TSMC 3nm-class node[3].
