The Intel HD Graphics 510 (GT1) is an integrated graphics unit, which can be found in low-end ULV (Ultra Low Voltage) processors of the Skylake generation. This "GT1" version of the Skylake GPU offers 12 Execution Units (EUs) clocked at up to 950 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 510 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).
Depending on various factors like memory configuration, the HD Graphics 510 should perform sligthly below the older HD Graphics 4400 and will handle modern games (as of 2015) only in lowest settings (if it does at all).
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 1.4a (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 HD Graphics 510 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.
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.

The following benchmarks stem from our benchmarks of review laptops. The performance depends on the used graphics memory, clock rate, processor, system settings, drivers, and operating systems. So the results don't have to be representative for all laptops with this GPU. For detailed information on the benchmark results, click on the fps number.
