What is the difference between intel uhd graphics and graphics card?

Hi. I guess you are asking about intel uhd and intel hd graphics. So let me brief you about both of them and you can yourself choose the better one. Here I am considering Intel UHD graphics 620 and Intel HD graphics 620.

Intel UHD Graphics 620

It is  is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake Refresh generation (8th generation Core).  It is clocked with up to 1.150 MHz and therefore 100 MHz higher than the old HD Graphics 620 (max. 1.050 MHz) and offer a comparable performance. The exact performance of the UHD Graphics 620 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model and as is similar to the Intel HD Graphics 620.

Intel HD Graphics 620

It is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Koby Lake generation. The exact performance of the HD Graphics 620 depends on various factors like L3 cache size, memory configuration (DDR3/DDR4) and maximum clock rate of the specific model but is very similar to the old HD Graphics 520 GPU. That means only some less demanding recent games like Farming Simulator 17 run fluently in low detail settings.

Hope this helps.

Hi, The Intel UHD Graphics 620 (GT2) is an integrated graphics unit, which can be found in various ULV (Ultra Low Voltage) processors of the Kaby Lake Refresh generation (8th generation Core). If it is compared to the similar named Intel HD Graphics 620 in the 2016 Kaby Lake CPUs, only the name changed from HD to UHD. I hope this answered you query!
