Powersaving and the New Ryzen Lineup

Framework Laptop 13

So, this might go a bit into crystal ball reading as I am under informed and struggled to get informations which is why I ask in the first place.

I currently own a 7640 Framework and I am quite happy with it. Apart from tons of stickers and some orange USB-C cards its basically a vanilla do it yourself Framework 13 from 2023.

I am currently running it under Linux which is not all that relevant right now. Battery life seems to be around 5 hours or so under most scenarios, it actually shows that it might be around 7 to 8 hours if I really limit the amount of stuff I keep running at a time and maybe did some additional tweaking. Sleep now works like a dream without issues. The only grief I still have is that KDE decides to go 100% cpu usage when in the lock screen, which is weird.

Anyway. New Ryzen Line Up. This is mostly for curiosity sake, one reason for going framework was to not change laptops like some influencer kid and their phone.

The current Ryzen 7040 line is quite powerful on the top end but the lower end is quite low so it is able to do a lot for less energy. I googled a bit around but couldnt really find out anything about the new Ryzen AI Stuff (I really despise that AI/LLMs are so in focus right now). Does the general public already know how efficient those will be? I assume that they are more powerful on the top end, but for my tiny 13’’ Laptop, the lower end and how low it goes is even more relevant. My smol 7640 is able to run Anno 1800 in 1440p which actually surprises me. So the high end is already quite satisfying.

tl;dr: Will the new Ryzen Generation be better at battery saving or does new high power performance mean that the lower power consumption threshold is higher compared to the 7040 Generation?

It’s obviously hard to say how it’ll work out in case of the Framework motherboard, but in general, Ryzen AI 300 is considered to be very efficient under light loads. I wouldn’t expect a huge leap in battery life as the manufacturing process is the same (TSMC 4nm). Maybe the Zen 5c cores help.

Also since you’re playing games, keep in mind that the iGPU of the Ryzen AI 5 340 is quite weak even in comparison to the 7640U, as it only has 4 CUs. The Ryzen AI 7 350 should be a little faster than the iGPU of the 7640U (both have 8 CUs, so not a huge difference I’d wager), with the Ryzen AI 9 HX 370 having 16 CUs (keep in mind that memory bandwidth and thermal/power limits probably doesn’t mean that 16 CUs equals “twice as fast”).
