The Intel Iris Pro Graphics 580 (GT4e) is an integrated graphics unit of the Skylake generation (top version). As successors of the Iris Graphics 6200 (Broadwell), the Iris 580 can be found in some high-end 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 Iris Graphics 550 (28 W GT3e), the Iris Pro Graphics 580 offers more EUs (72 vs. 48) and a larger eDRAM Cache (128 vs. 64 MB).
Performance
The exact performance of the Iris Graphics 580 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.
Features
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.
Power Consumption
The Iris Graphics 580 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.
The Nvidia Quadro P4200 is a mobile high-end workstation graphics card for notebooks. It is based on the GP104 chip (like the consumer GeForce GTX 1070 or 1080 for laptops) and features 2304 shader cores. The clock rate is not disclosed but the theoretical SP performance is rated at 8.9 TFLOPs (for the fast Max-P version) and therefore faster than the old Quadro P5000 but below the Quadro P5200 (see table below). The P4200 is equipped with 8 GB GDDR5 which leads to 224 GB7s peak bandwidth due to the 256 Bit memory bus. There are two variants available, a Max-P performance version and a Max-Q version tuned for efficiency (with lower clock speeds).
The Quadro GPUs offer certified drivers, which are optimized for stability and performance in professional applications (CAD, DCC, medical, prospection, and visualizing applications). The performance in these areas is therefore much better compared to corresponding consumer GPUs.
Power Consumption
The power consumption of the Quadro P4200 is rated at 115 Watt TGP (max power consumption incl. memory) and therefore 15 Watt more than the Quadro P5000. The card is therefore best suited for large 17-inch notebooks.
