Intel Iris Plus Graphics 655

Intel Iris Plus Graphics 655

英特尔Iris Plus图形655(GT3e)是2017年9月发布的处理器集成显卡。作为英特尔Iris Graphics 650(Kaby Lake)的继承者,Iris Plus Graphics 655用于28瓦Coffee Lake-U型号。最大的区别是128 MB的双倍eDRAM缓存。与Iris Graphics 650相比,不应有任何明显变化。

所谓的Kaby Lake GPU的GT3e版本仍然有48个执行单元(EU),根据型号的不同,它可以达到1200 MHz(之前是1100 MHz)。除了eDRAM缓存之外,Iris 655还可以通过处理器接口访问系统内存(2x 64位DDR3L-2133 / DDR4-2400)。

与15瓦型号的Iris Plus 640相比,Iris 655仅具有略高的最大时钟频率以及几乎两倍的TDP,从而可以更好地利用Turbo Boost的潜力。

性能

Iris Plus Graphics 655的确切性能取决于CPU型号,因为最大时钟以及L3缓存的大小可能略有不同。系统内存(DDR3 / DDR4)也会影响性能。

最快的芯片是Core i7-8559U等高频率Core i7型号。根据游戏的不同,Iris Plus 655可能与专用的GeForce 930M或GeForce 940MX相媲美,可以在低至中等设置的现代游戏中流传的运行游戏。

功能

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。然而,与Skylake相反,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。可通过DP 1.2 / eDP 1.3(最高3840 x 2160 @ 60 Hz)输出视频,而旧的1.4a标准也支持HDMI。可以通过DisplayPort转换器添加HDMI 2.0输出。GPU可以同时驱动多达三个显示器。

能耗

Iris Plus Graphics 655用于28瓦处理器,因此适用于中小型笔记本电脑。
