AMD Radeon 620
The Radeon 620 is a dedicated entry-level graphics card for laptops that was released in 2019. According to AMD there are two versions of the GPU one with 5 CUs and most likely higher clock speeds and a 6 CU version with 384 cores. Furthermore, the chip can be paired with slow DDR3 (maybe for the 6 CU version) and faster GDDR5. The chip is most likely not based on any current architecture like Navi or even Polaris, but still the old Sun chip from 2014 (e.g. from the Radeon R5 M230 and later up to M440 and Radeon 520).
The performance depends of the used version and graphics memory, but should be somewhere between a Radeon 520 and 530 in the absolute entry level. That means, only a few modern games like Dirt Rally 2.0 should run fluently on the GPU.
