mind you coding doesn't require any power at all unless you're going to be a game dev or ML enthusiast, it just needs ram, for gaming as well 13900hx absolutely shreds the amd to dust, lol 70% better multi core and double the L3 cache it's not even close, amd is just there for a sweet spot between efficiency and performance especially in handhelds... however for the dudes spending that much I guess a Ryzen x3d would be much better unless it's a deal that has lower prices ... 7840hs is only considerable when you absolutely need more than 3-4 hours of battery life
