由于Core 2 Duo T7600进一步提升ALU架构，并提升内存读取技术，因此游戏测试性能对比Core Duo T2600有明显的提升。
后记
根据市调机构 Gartner 2006 年 5 月的全球 PC 出货量预估报告指出， 2001 年时桌面计算机与移动计算机比例为 8 ： 2 ，但近年来移动计算机已逐渐普及，两者比例已缩短为 7 ： 3 情势，预计 2008 年将会达至 6 ： 4 的惊人数字，因此处理器双雄均积极为下一个主战场 -- 移动计算机市场全力备战。
事实上，全新 Merom 处理器除继承 Yonah 的优良设计外，性能也更上一层楼，同时功耗表现亦维持一贯高水平，可望进一步扩大市场优势，成为压制 AMD Turion X2 、捍卫市占的最佳利器。
值得关注的是，由于 Napa Refresh 平台与 2007 年第二季将接棒的 Santa Rosa 平台脚位并不兼容，未来 2 平台转换是否顺畅，成为各大厂商备货的重大考虑关键，据 NB 厂商指出，倘若 Intel 规划失败导致库存满手，恐让 AMD 抓住见缝插针的难得时机。
