My daughters is the Ryzen 5 2500u. It's decent, I would guess that one is better, think it still has the same Vega 8 graphics. As said before the graphics are never going to be as good as a dedicated gaming card, but I'm sure that they're better than Intel's built in graphics at that price point. It's why I bought it, my daughers previous Lenovo Yoga with Intel graphics struggled with games like The Sims and Roblox (The Sims more so), the R5 2500u doesn't. Depends what you want it for really, nice to have regardless though. HP have always been good, the ones I've had anyway.The spec says R5-3500U, also the Argos one is a HP, not Lenovo.
Edit: just noticed that JL also have a HP with a Ryzen 5 3500U.
