七大预测揭开AI供电革命拐点!英飞凌白皮书前瞻下一代技术
Hua Er Jie Jian Wen· 2025-12-24 05:55
英飞凌最新白皮书提出七大关键预测,描绘了AI供电的未来图景:未来十年,单颗处理器负载电流将达到10,000安培,是当前水平的10倍;电源 架功率等级将突破100千瓦;AI服务器机架功耗将突破1兆瓦;数据中心功耗需求将迈向吉瓦级规模...... 该公司电源与传感器系统事业部总裁Adam White指出,自2022年底ChatGPT发布以来,AI技术的指数级增长带来了前所未有的功率需求挑战,迫 使行业不断突破创新边界。 这些预测涵盖了从垂直供电技术到直流微电网的全方位变革,将对数据中心运营商、设备制造商和投资者产生深远影响。随着AI工作负载的持续 增长,传统的48V供电架构将被高压直流系统取代,而可再生能源的整合也将成为满足庞大能耗需求的关键。 预测一:垂直供电将主导未来处理器架构 英飞凌预测,垂直供电将成为现代处理器的关键技术。 白皮书指出,GPU和TPU采用最先进工艺制程(如台积电N4P),通过多片硅片集成突破单一制程限制。随着芯片尺寸增大、供电电压降至约 0.4V,总电流消耗预计十年内攀升至10,000安培。传统横向供电方式在如此高电流下占用空间庞大且损耗显著,电能将通过主板垂直传递至处理 器背面。 这场由 ...
