Today we’re completing our testing of AMD’s Ryzen Mobile 4000 APUs with a look at the Ryzen 7 4700U and Ryzen 5 4500U, two mainstream chips in the series that have become available in a wider range of laptops in the past few weeks. Testing all of AMD’s Zen 2 APUs has been a challenge due to laptop availability – these chips launched way back in March – but today we can find several ultraportables from the likes of Lenovo, HP, Asus, Acer, and others sporting these processors, making this review to a must to follow up to our 4800U, 4800H, and other APU testing.
