Intel Iris Plus Graphics 640 or also known as GT3e is an integrated graphics processor used in ULV (Ultra-low voltage) chips from intel that are part of the Kaby Lake generation processors. The GT3e core boasts 48 Execution Units (EUs) that are clocked up to 1050 MHz, depending on the CPU model. The graphics processor supports up to DDR3L-1600 or DDR4-2133 RAM and uses two channels for reaching maximum bandwidth.
The iGPU now supports H.265/HEVC hardware decoding but the most notable feature here is that the chip supports DisplayPort 1.2 (max. resolution: 3840 x 2160 @ 60 Hz) while the HDMI support is limited to the older 1.4a. The GPU can support up to three displays simultaneously. The power consumption of the whole chip (along with the CPU and memory controller) is 15W.
