Intel HD Graphics 520 vs Intel Iris Graphics 540 vs Intel HD Graphics 530

Intel HD Graphics 520

The Intel HD Graphics 520 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Skylake generation. This "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 520 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Performance

The exact performance of the HD Graphics 520 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model. The fastest versions (Core i7-6600U) should perform similar to a dedicated GeForce 820M and will handle modern games (as of 2015) in low 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 HD Graphics 520 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.

Intel Iris Graphics 540

The Intel Iris Graphics 540 (GT3e) is an integrated graphics unit of the Skylake generation. As successors of the HD Graphics 6000 (Broadwell), the Iris Graphics 540 can be found in CPUs of 15-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 1050 MHz (depending on the CPU model). Besides the eDRAM cache, the Iris 540 is able to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Compared to the Iris Graphics 550 of the 28-watt series, the Iris Graphics 540 differs only by its slightly lower maximum clock and a nearly halved TDP, which limits the utilization of the Turbo Boost in certain situations.

Performance

The exact performance of the Iris Graphics 540 depends on various factors like memory configuration (DDR3/DDR4) and maximum clock rate of the specific model. The fastest versions (Core i7-6650U) should be slightly ahead of a dedicated GeForce 920M and will handle modern games (as of 2015) in low or medium settings.

The Iris Graphics 540 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks.

Intel HD Graphics 530

The Intel HD Graphics 530 (GT2) is an integrated graphics unit, which can be found in various desktop and notebook processors of the Skylake generation. The "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1150 MHz (depending on the CPU model). Due to its lack of dedicated graphics memory or eDRAM cache, the HD 530 has to access the main memory (2x 64bit DDR3L-1600 / DDR4-2133).

Performance

The exact performance of the HD Graphics 530 depends on various factors like TDP, L3 Cache, memory (DDR3/DDR4) and maximum clock rate of the specific model. The fastest desktop versions (Core i7-6700K) can compete with a dedicated GeForce 920M and will handle modern games (as of 2015) in low or medium settings.

Features

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 HD Graphics 530 can be found in several notebook and desktop processors of different TDP classes (35 - 91 W).
