At a time, we can connect a maximum of 3 displays with this Graphics Processor. The DirectX and OpenGL versions are 12 and 4.4 respectively. It supports 4K at 60Hz and the maximum display resolution can be 4096 x 2304 pixels. The Processing Power of UHD 620 is 422.4 − 441.6 GFLOPS which is once again higher than HD 620 (384 – 403.2 GFLOPS).

In the case of Core-i5 (8250U and 8350U), the max frequency is 1.10 GHz and for Core-i7 (8550U and 8650U), it is equal to 1.15 GHz.

However, the max GPU frequency is higher than HD 620 and it is 1.10 or 1.15 GHz. The base frequency of this GPU is 300 MHz and it is same as the previous generation HD 620 Graphics. It can support a maximum VRAM/Graphics Memory of 32 Gigabytes and the memory type will be same as the RAM. It is based on the 14nm Tri-Gate (FinFET) fabrication technique. The Thermal Design Power (TDP) is equal to 15W which is same as the Processor. Compared to the previous generations, this has some new features such as 10-bit colors, H.265/HEVC Main 10 Profile, and HDCP 2.2. It is based on the Kaby Lake Refresh Architecture. This Graphics Processing Unit is Integrated with the Intel’s 8th Generation Notebooks Processors.
