Intel HD Graphics 620

Intel HD Graphics 620

英特尔UHD Graphics 620 (GT2)作为一个集成显卡,可以在许多ULV(超低电压)的Kaby Lake Refresh(第八代)中央处理器中找到。对比与它拥有类似名字的英特尔HD Graphics 620(在2016年的Kaby Lake处理器中),只不过是名字从HD变为了UHD。它的时钟频率高达1.150 MHz,比先前的HD Graphics 620(最高1.050 MHz)高出 100 MHz,可以提供更优秀的性能。而由于缺乏专用的图形内存和aeDRAM缓存,HD 620 必须占用主内存(2x 64bit DDR3/DDR4)。

性能

UHD Graphics 620的真实性能取决于很多因素,比如:三级缓存的大小、配套的内存条(DDR3/DDR4),以及特定型号的最高时钟频率。这点和英特尔HD Graphics 620、HD Graphics 630相类似。在我们的游戏指标下,与HD Graphics 620的平均水平相比,四核处理器使得UHD显卡略有提升。因而,它的排位应该处于,英伟达GeForce 910M和920M,这两款集显之间。

应用于游戏时,驱动程序的更新和测试没有像Gefore显卡那么频繁。在我们的测试中,UHD 620适合休闲游戏,例如《军团要塞2》、《火箭联盟》、《模拟农场17》。请参阅下面不同型号下,各个被测试的游戏名单。

特点

调整后的视频引擎,支持10位颜色的H.265 / HEVC Main10 profile的硬件。此外,Googles VP9编解码器也可以被硬件解码。第一个型号不支持HDCP 2.2,因此也不支持Netflix 4K。2017年和2017年5月初新发布的这款产品,以及像i3-7100U这样的老款处理器,还附带支持HDCP 2.2的新S-Spec代码。然而,HDMI 2.0仍然只支持外部转换芯片(LSPCon)。

能耗

UHD Graphics 620可以在15W热设计功耗的移动处理器中找到,因此适用于紧凑型笔记本电脑和超极本。运行“巫师3”(外接显示器)时的功耗与基于英特尔HD Graphics 620的笔记本电脑相当,处于我们所有测量值的最低端。而像GeForce 940MX这样的专用显卡则需要更多的能耗。
