Intel Iris Graphics 550 vs Qualcomm Adreno 506 vs Qualcomm Adreno 540

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.

Qualcomm Adreno 506

The Qualcomm Adreno 506 is a mobile graphics card for mid-range smartphones and tablets (mostly Android based). It is included in the Qualcomm Snapdragon 625 SoCs and based on the Adreno 500 architecture (like the Adreno 520 in the S820, which should be fully compatible in software).

The GPU supports modern standards like Vulkan 1.0 (according to Wikipedia), OpenGL ES 3.1 + AE (3.2 in other sources), OpenCL 2.0 and DirectX 12 (FL 12.1 according to Wikipedia, 11.1 according to Qualcomm). Furthermore, the GPU supports Universal Bandwidth Compression (UBWC) to save memory bandwidth.

Qualcomm Adreno 540

The Qualcomm Adreno 540 is an integrated graphics card in the Qualcomm Snapdragon 835 SoC for smartphones. It was introduced in early 2017 and can be found in high-end Android smartphones. 

The integrated GPU is based on the optimized architecture of the Adreno 530, but features clearly improved clock speeds (710 versus 624 MHz according to Anandtech) and better thermal stability. This is also thanks to the new 10 nm process the Snapdragon 835 is produced in. In the reference smartphone from Qualcomm, the Adreno 540 is able to beat or perform at a similar level as the fastest smartphone graphics cards on the market (e.g. the ARM Mali-T880MP12, ARM Mali-G71MP8 or Apple A10 GPU). Therefore, it should be perfectly suited for demanding 3D gaming and also mobile VR and 4K displays.
