这个补丁更新了应该老CPU应该性能会下降，反正X230更新了，感觉有点影响，慎重！！！ 老CPU影响在50%，还是算了 更新cve漏洞, 我不更新算了 前几天更新后不识别msata硬盘，后来刷回1.28，问题解决 220的CPU应该不差吧，我看X220的I5-2450M与X270的I5-6200U，百万superPI的数值都是13秒左右，性能相近。
主要的差别可能就是耗电。 xqinshan 发表于 2018-3-26 14:03

是的 我的3920xm和4910mq 基本没差别 asakawalan 发表于 2018-3-26 15:24

CPU核心基本没区别。但3代的内存频率只有DDR3-1866，而4代提升到了DDR3-2133、瓶颈环节更强、好于3代U。 更新后可以识别msata SSD。检测漏洞问题已通过。 更新后可以识别msata SSD。检测漏洞问题已通过。 准备X220批量淘汰，应该升CARBONX1 2015感觉不错 Valkyrie1996 发表于 2018-4-10 00:38

区别大了好吧，AVX2带来的浮点运算能力提升40%
