Intel Iris Graphics 550

The Intel Iris Graphics 550 (GT3e) is an integrated graphics unit of the Skylake generation. As successors of the Iris Graphics 6100 (Broadwell), the Iris Graphics 550 can be found in CPUs of 28-watt series and offers 64 MB of dedicated eDRAM memory. Furthermore, the so-called GT3e-version features 48 Execution Units (EUs) clocked at up to 1100 MHz (depending on the CPU model). Besides the eDRAM cache, the Iris 550 is able to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Compared to the Iris Graphics 540 of the 15-watt series, the Iris Graphics 550 differs only by its slightly higher maximum clock and a nearly doubled TDP, which allows a better utilization of the Turbo Boost.

Performance

The exact performance of the Iris Graphics 550 depends on various factors like L3 Cache size, memory (DDR3/DDR4) and maximum clock rate of the specific model. The fastest versions (Core i7-6567U) may compete with a dedicated GeForce 930M and will handle modern games (as of 2015) in low or 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 1.4a (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.

Power Consumption

The Iris Graphics 550 can be found in mobile processors specified at 28 W TDP and is therefore suited for medium-sized laptops and ultrabooks.
