Intel UHD Graphics 620

Intel UHD Graphics 620

英特尔UHD Graphics 620(GT2)是一个集成显卡,可以在Kaby Lake Refresh代(第8代Core)的各种ULV(超低电压)处理器中找到。与2016年Kaby Lake 处理器中的Intel HD Graphics 620相比,只是名称从HD改为UHD。它的时钟频率高达1.150 MHz,因此比旧的HD Graphics 620(最高1.050 MHz)高出100 MHz,并且具有相当的性能。由于缺乏专用图形内存或eDRAM缓存,HD 620必须访问主内存(2个64位DDR3 / DDR4)。

性能

UHD Graphics 620的确切性能取决于各种因素,如三级高速缓存的大小,内存配置(DDR3 / DDR4)以及特定型号的最大时钟频率。这与英特尔HD Graphics 620和英特尔HD Graphics 630相似。在我们的游戏基准测试中,对比HD Graphics 620平均水平,四核处理器下的UHD显卡更优秀些。因此,排位应该放置在Nvidia的GeForce 910M和920M专用显卡之间。然而,如果应用于游戏,驱其动程序并不像GeForce显卡那样频繁的更新和测试。在我们的测试中,UHD 620最适合休闲游戏,如军团要塞2,火箭联盟或模拟农业17。请参阅下面的用于测试各种型号的游戏的列表。

特点

改良后的视频引擎,现在支持以10位颜色硬件的H.265 / HEVC Main10编码。此外,Googles VP9编解方式也可以被硬件解码。第一款机器不支持HDCP 2.2,因此也不支持Netflix 4K。2017年和2017年5月初新增加的这款产品,以及像i3-7100U这样的老款中央处理器现在还附带支持HDCP 2.2的新S规格代码。而HDMI 2.0仍然只支持外部转换芯片(LSPCon)。

能耗

UHD Graphics 620可以在15 W TDP的指定移动处理器中找到,因此适用于小型笔记本电脑和超极本。在玩“巫师3”(带外部显示器)时的功耗与基于英特尔HD Graphics 620的笔记本电脑相当,也是我们所有测量到数据的最低值。像GeForce 940MX这样的专用显卡需要更多的功率。
