Intel HD/UHD Graphics 620
The Intel HD/UHD Graphics 620 (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 64-bit DDR3L-1600/DDR4-2133).
Performance
The exact performance of the HD/UHD Graphics 620 depends on various factors like L3 cache size, memory configuration
(DDR3L/DDR4) and maximum clock rate of the specific model.
Features
The revised video engine now decodes H.265/HEVC completely in hardware and more efficiently than before. Displays can be
connected using a 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 620 can be found in mobile processors specified at 15 W TDP and is therefore suited for compact laptops and
Ultrabooks.
