The Radeon 620 is a dedicated entry-level graphics card for laptops that was released in 2019. According to AMD, the GPU offers 6 compute units (CUs = 384 shaders) and 4 GB GDDR5 (64 bit bus) graphics memory (max). The chip is most likely not based on the current Navi or even older Polaris architecture, but still based on the the old Mars chip from the Radeon HD 8590M / M260 / M340 / M440 and Radeon 530.
Therefore, the gaming performance is positioned in the absolute entry level (see the similar Radeon 530). Only a few modern games like Dirt Rally 2.0 should run fluently in low settings.
The AMD Radeon RX 640 is mobile mid-range graphics card for laptops based on the Polaris architecture. It features 640 shaders (10 CUs) or 512 shaders (8 CUs) with different clock speeds. Compared to the older RX 550(X), the RX 640 seems to offer only half of the memory bandwidth (64 Bit memory bus instead of 128 Bit).
The performance should be slightly lower than the old RX 550 and therefore a Nvidia GeForce MX150. Only low demanding games are therefore playable with the GPU. In our benchmarks of the Thinkpad E15 the RX640 is slightly slower than an average GeForce MX330 (+4%) / MX250 / MX150. Therefore, the performance may not be enough for very demanding games. For example, Ghost Recon Breakpoint only achieved 26 fps on average in the lowest settings.

Game Benchmarks
The following benchmarks stem from our benchmarks of review laptops. The performance depends on the used graphics memory, clock rate, processor, system settings, drivers, and operating systems. So the results don't have to be representative for all laptops with this GPU. For detailed information on the benchmark results, click on the fps number.
