EVGA SC17 GTX 1070 笔记本电脑简短评测
Intel Core i7-6820HK | NVIDIA GeForce GTX 1070 Mobile | 17.30" | 4.1 kg
英特尔酷睿i7-6820HK是一颗基于Skylake架构的四核处理器,已在2015年9月发布。 除了四个支持超线程的CPU核心运行于2.7 - 3.6 GHz(四核:最大3.2 GHz,双核:最大3.4 GHz),该芯片还集成了HD Graphics 530显卡和双通道DDR4- 2133 / DDR3L-1600内存控制器。 该CPU采用14纳米工艺与FinFET晶体管制造工艺。
目前,i7-6820HK是唯一未锁倍频的Skylake架构处理器(类似于以前的Extreme版)。
架构
Skylake架构取代了Haswell和Broadwell,为从4.5到45瓦热设计功率的处理器都提供了相同的微架构。Skylake架构设计的众多改进包括增加了乱序缓冲,优化的预取和分支预测以及超线程模式的性能改进。 不过整体上,它的单位时钟频率性能仅增加了5%到10%(相比Haswell)而相比Broadwell架构不足5%,这对于一个新架构(“Tock”)来说十分低。
性能
得利于改进的架构,酷睿i7-6820HK的性能应与前代酷睿i7-4900MQ(Haswell)或酷睿i7-5700HQ(Broadwell)相当。 在长时间负载下,Skylake芯片应该可以凭借更加先进的14纳米制程带来的更高能效和更低发热量占据优势。 如果6820HK超频的话(我们测试过所有4个内核最高运行于4.0 GHz),性能会更强。
它可以轻松承担大型软件或繁重多程序运行的任务。
图形
它的集成显示单元名为HD Graphics 530,代表了Skylake显卡的"GT2"版本(Intel第九代)。 它的24个执行单元,也被称为EU,主频在350-1050 MHz之间,提供的性能高于前代HD Graphics 4600约20%。 2015年的游戏应该可以在低中设置下流畅运行。 有关性能和功能的详细信息,请参考我们的HD Graphics 530页面。
功耗
设计热设计功率45瓦(包括CPU,GPU和内存控制器),这款处理器最适合于15英寸或更大的笔记本电脑。 它的TDP也可以降低到35瓦(cTDP降低),从而同时降低发热量和性能。
