联想 U31-70 80M5003EGE 笔记本电脑简短评测
Intel Core i7-5500U | NVIDIA GeForce 920M | 13.30" | 1.5 kg
英特尔酷睿i7-5500U是一颗ULV(超低电压)双核处理器,基于Broadwell架构,在2015年1月发布。除了两个支持超线程、运行频率2.4 - 3.0 GHz的处理器核心(双核心:2.9GHz),该芯片还集成了HD Graphics 5500显卡和双通道DDR3(L)-1600内存控制器。酷睿i7采用14纳米工艺与FinFET晶体管技术制造。
相比酷睿i7-5550U,i7-5500U具有更高的处理器基本时钟频率,但集成了较慢的显卡。
架构
Broadwell是Intel的滴答模式中的“滴”,这意味着它是基于前代Haswell架构进行了制程缩减。新的14纳米支撑技术配合三维FinFET晶体管技术不仅提高了能效,也帮助芯片尺寸得到了明显减小,让设备可以更加紧凑。
其他的优势来自于Broadwell在系统微架构上面的改进。由于在分支预测上得到了优化,加上采用了更大的缓存容量(L2 TLB中1500个条目相比前代的1000个)和其他的优化,它的单位时钟频率性能相比前代产品有了超过5%的提升。它同样提供了为加密应用设计的一些新指令集的支持。
性能
由于其改进的架构,酷睿i7-5500U性能可以超过频率略低的酷睿i7-4500U(Haswell,15 W)约5 - 15%,和同频率的i5-4258U(Haswell,28 W)表现相当。因此,这颗处理器的性能足以满足办公和多媒体用途的需要,也可以胜任复杂的应用程序和多任务处理。
图形
集成的HD Graphics 5500提供了24个执行单元(EU),运行于300到950MHz。与处理器核心相似的是,它的显卡架构(Intel Gen 8)也在单位时钟频率性能上得到了改进。因此,HD Graphics 5500性能优于HD Graphics 4400(20个EU)以及HD Graphics 5000(40个EU),它们均属于Haswell架构。尽管如此,大多数2015年的游戏将只能在低设置下运行。
Broadwell是Intel的第一块全面支持DirectX 11.2和OpenCL 1.3/2.0与OpenGL 4.3的芯片。它的原生视频信号可以通过DisplayPort 1.2或HDMI 1.4a输出。不过,它并不支持最新的HDMI 2.0标准。
功耗
i7-5500U包括图形芯片,内存控制器和VRM的热设计功率为15瓦(可降低到7.5瓦)。因此,这款处理器适合于11寸的小型超极本或更大的笔记本电脑。
