So which CPU will you choose: AMD Ryzen 7 7735HS or Ryzen 7 7840HS?

Well if you already have 7735HS performance jump is a lot. So I would stick with 7735 but if you have 6900hx even with Radeon 680 the higher-end 7735HS is closer to 7740HS. So if you have 6900hx, not the 7000 series then yes I would upgrade. if not 7735HS is too close so I would not upgrade.
