AMD Radeon 610 vs AMD Radeon 620 vs AMD Radeon RX 640
AMD Radeon 610► remove from comparison
The Radeon 610 is a dedicated entry-level graphics card for laptops that was released in 2019. It is the slowest dedicated graphics card from AMD in 2019 and a rename of the old Radeon 520. Therefore, it is not based on the newer Polaris or even Navi architecture, but should use the old Sun chip from 2014 (Radeon R5 M230 e.g.).
The performance should be similar to the integrated Intel UHD Graphics 620 and therefore, the gaming performance is only suited for very low demanding games. Look at our benchmarks of the similar Radeon 520 for reference.
AMD Radeon 620► remove from comparison
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.
AMD Radeon RX 640► remove from comparison
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.
