The AMD Radeon RX 550X 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. The clock rate in the Lenovo Thinkpad E590 is 1176 MHz although AMD states up to 1287 MHz in the specifications (including the desktop version).
The performance should be similar to a Nvidia Geforce MX250 and therefore suited only for entry level gaming (e.g. less demanding games like Dota 2 or World of Tanks).
According to our information, the RX 550X is currently sold with 4 GB GDDR5 memory for around 30 - 40 dollars to laptop manufacturers.
The AMD Radeon RX 580X is a fast mid-range graphics card for laptops. It is based on the Polaris 20 chip and basically a rebrand of the mobile RX 580. Compared to the Polaris 10 in the similar RX 480, the Polaris 20 is manufacted in an improved 14nm process (LPP+) for higher clock speeds and some power efficiency improvements in idle. The performance in laptops depends on the used clock speeds and should be similar to the desktop RX 470 (see for gaming benchmarks) or even RX 480.
