Due to its lack of dedicated graphics memory or eDRAM cache, the HD 620 has to access the main memory (2x 64bit DDR3/DDR4). This "GT2" version of the Kaby Lake GPU is clocked at up to 1050 MHz (depending on the CPU model). The Intel HD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake generation. Intel HD Graphics 620 ► remove from comparison The HD Graphics 520 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and ultrabooks. However, HDMI 2.0 can be added using a DisplayPort converter. Up to three displays can be controlled simultaneously. 3840 x 2160 60 Hz), whereas HDMI is limited to the older version 1.4a (max.
Displays can be connected via DP 1.2 / eDP 1.3 (max.
The revised video engine now decodes H.265/HEVC completely in hardware and thereby much more efficiently than before. 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.
The exact performance of the HD Graphics 520 depends on various factors like 元 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific 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). This "GT2" version of the Skylake GPU offers 24 Execution Units (EUs) clocked at up to 1050 MHz (depending on the CPU model). 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.
