华硕ROG Strix SCAR III G531GW (i9-9880H, RTX 2070) 笔记本电脑评测
Intel Core i9-9880H | NVIDIA GeForce RTX 2070 Mobile | 15.60" | 2.3 kg
英特尔酷睿i9-9880H是一款高端笔记本电脑处理器,具有基于Coffee Lake架构的八核笔记本电脑(2019年更新,CFL-HR)。处理器的时钟频率在2.3-4.8 GHz(8核睿频4.1 GHz)之间,并且借助超线程技术可以同时执行多达16个线程。能使用“ Thermal Velocity Boost”达到4.8 GHz,只要CPU温度低于50°C,该内核就可以将一个内核提升到4.8 GHz(+200 MHz)。多个内核可以在50°C以下以+100 MHz的频率下提升(未经验证)。与之前的Core i9-8950HK相比,9980H基于相同的架构,但多提供了2个内核。
据英特尔称,该CPU采用改进的14nm(14nm ++)工艺制造。在发布之时,i9-8950HK是Coffee-Lake-H系列中最快的型号,并提供用于CPU超频的解锁倍频器。
Coffee Lake体系结构与Kaby Lake类似,仅内核数量(高端版本现在为6个内核)和改进的14nm工艺(英特尔表示为14nm ++)不同。
性能
由于增加了两个内核,与类似怕频率的前辈相比,性能提高了近33%,与较旧的Kaby-Lake四核相比,性能甚至提高了100%。但是,单线程性能仅略有提高,而多核性能在很大程度上取决于散热效果。
图形
集成的Intel UHD Graphics 630 iGPU的时钟频率提高了50 MHz,因此可以提供更高的性能。该架构与Intel HD Graphics 630的架构相同。我们确实希望性能有所提高,但作为低端解决方案,它可能只会以低特效(如果有的话)运行游戏。
能耗
英特尔指定TDP的功耗为45瓦,因此i9仅适用于具有良好散热解决方案的大型笔记本电脑。
