Intel Iris Pro Graphics P580
The Intel Iris Pro Graphics P580 (GT4e) is an integrated professional graphics unit of the Skylake generation (top version). As successors of the Iris Graphics 6200 (Broadwell), the Iris P580 can be found in some high-end Xeon quad core CPUs and offers 128 MB of dedicated eDRAM memory. Furthermore, the so-called GT4e-version features 72 Execution Units (EUs). Besides the eDRAM cache, the Iris 580 is able to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).
Compared to the consumer Iris Pro Graphics 580, the P580 is only included in the Xeon processors and intended for professional applications (certified drivers?) similar to the Quadro and Fire Pro lines.
Compared to the Iris Graphics 550 (28 W GT3e), the Iris Pro Graphics P580 offers more EUs (72 vs. 48) and a larger eDRAM Cache (128 vs. 64 MB).
The exact performance of the Iris Graphics P580 depends on memory configuration and CPU model (different clock speeds). However, it should be clearly faster than the old Broadwell Iris Pro 6200 and may compete with a dedicated GeForce 945M. Modern games of 2015/2016 should be playable in medium settings.
The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. Displays can be connected via DP 1.2 / eDP 1.3 (max. 3840 x 2160 @ 60 Hz), whereas HDMI is limited to the older version 1.4 (max. 3840 x 2160 @ 30 Hz). However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously.
The Iris Graphics P580 can be found in some mobile high-end quad core processors (45 W). Therefore, they are most likely not used in thin and light laptops.
