The Radeon 620 Mobile is a graphics card by AMD, launched in May 2019. Built on the 28 nm process, and based on the Weston graphics processor, in its Weston PRO variant, the card supports DirectX 12.0. The Weston graphics processor is an average sized chip with a die area of 125 mm² and 3,100 million transistors. It features 384 shading units, 24 texture mapping units and 8 ROPs. AMD has placed 2,048 MB DDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 730 MHz, which can be boosted up to 1024 MHz, memory is running at 900 MHz.
Being a igp card, the AMD Radeon 620 Mobile does not require any additional power connector, its power draw is rated at 50 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon 620 Mobile is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
