Intel Iris Plus Graphics 645

Intel Iris Plus Graphics 645

英特尔Iris Plus Graphics 645(GT3e)是一种处理器图形卡,于2019年中首次出现在Apple MacBook Pro 13(入门版,2019)中。它与28瓦CPU中的Iris Plus Graphics 655类似。

所谓的Coffee-Lake GPU GT3e版本仍然具有48个执行单元(EU),根据型号的不同,它们的频率可以达到1150 MHz。除eDRAM缓存外,Iris 645还可以通过处理器接口访问系统内存(2个64位DDR3L-2133 / DDR4-2400)。

性能

Iris Plus Graphics 645的确切性能取决于CPU型号,因为最高频率以及L3缓存的大小可能会有所不同。系统内存(DDR3 / DDR4)也将影响性能。

最快的芯片是诸如Core i7-8557U之类的高频率Core i7型号。根据游戏的不同,Iris Plus 655的性能可能会与GeForce 930M或GeForce 940MX相提并论,并且可以在低至中的画质设置流畅的运行现代游戏。

特征

经过重新设计的视频引擎现在完全支持H.265 / HEVC视频的硬件解码。与Skylake不同,Kaby Lake现在还可以解码具有10位色深的H.265 / HEVC Main 10以及Google的VP9编解码器。可以通过DP 1.2 / eDP 1.3(在60 Hz时高达3840 x 2160 @ 60 Hz)进行视频输出,而较早的1.4a标准也支持HDMI。可以通过DisplayPort的转换器添加HDMI 2.0输出。 GPU最多可以同时驱动三个显示器。

能耗

Iris Plus Graphics 645用于15瓦处理器,因此适用于小型笔记本电脑。
