Default 台积电28nm制程助Cortex-A9双核处理器冲上3GHz

台积电今日官方宣布该公司新ARM Cortex-A9双核心处理器测试芯片的频率已经超过3GHz。据称这款产品基于28nm HPM(High Performance Mobile,高性能移动计算)制程工艺,最高频率可达3.1GHz,而目前人们印象中的双核移动处理器频率范围通常在1.0-2.0GHz之间。当然A9依然是A9,这也仅仅是最大代工厂台积电的一个探索。毕竟更新架构的Cortex-A15产品已经蓄势待发,虽然台积电表示3GHz频率的双核心Cortex-A9处理器性能对比现今的40nm制程A9产品可达两倍之多,但架构仍然是旧的。资讯网站Fudzilla分析,这仅仅是台积电的一种技术展示行为,由于各大厂商在今年下半年至明年上半年都计划推广采用Cortex-A15架构处理器的产品。用户很难看到频率超过2GHz的A9处理器出现在智能手机/平板电脑当中。
