I currently have the AMD Ryzen 5 7640U CPU and want to upgrade my mainboard to Ryzen AI 9 HX 370 (preferred, but worried about noise & heat) or Ryzen AI 7 350 (a decent upgrade from my current mainboard). For folks who have gone through this upgrade, can you please speak to how the two CPUs compare on (a) noise, (b) heat, (c) performance, and (d) battery life?
I’m not interested in benchmarks, just observation and perception based on real-world use (of folks who have upgraded from 7040 series to the AI series). Real-world use that involves software development, VMs, Video/Audio editing, and even local AI would be awesome.
That seems more of a side-grade.

You’re likely on-point here. My understanding was that the Ryzen AI 7 350 was closer to, and an improvement over, 7840 except in raw GPU perf where it’s a slight downgrade. The AI 9 HX 370 is the true upgrade, and that’s what I want to get, but am concerned about its perf, battery life, noise and heat signatures in the FW 13 chassis.
In cpu wise the ai has the same number of cores but that is made up of 4 better zen5 cores and 4 likely worse zen5c cores vs 8 full fat zen4 ones and the gpu is quite a bit worse. It is not as bad as the 340 vs the 7640u though (unless someone really has an application for the npu idk why anyone would pay for the 340 as long as the 7640u is available).
Even the 370 isn’t that much better compared to what you have. If you really need more multicore performance or play stellaris 24/7 go for it, otherwise maybe stick with what you have for now.
Personally even if I did want the 370 after the experience of early adopting the 7480u I’d still wait a couple more moths before even considering it. Battery live and idle power was pretty bad there too early on.

I upgraded from the R7 7840U to the R9 AI HX 370 and I have found that gaming performance improved (7840U was still borderline, HX370 is playable); however the power usage and heat output of the HX370 is quite a bit more while doing simpler tasks (apps open but otherwise “idle”).
This will hopefully improve in time. (I run Linux, and 7840U took a little while to optimize.)

I think 7840U is still the best AMD FL13, good efficiency on both light and heavy tasks, best performance-to-cost in GPU

This may get better with time, the 7480u also had a pretty rough start in that department. Would be nice if someone would start shipping stuff in a semi finished state but it is what it is.
The 7640u may have it beat in that department, especially if we are talking mainboard only prices. In the 13 we are still more power limited than core limited so having 4 fewer gpu cores doesn’t hurt as much as if it was unconstrained.

I have no doubts it will! This community that we have here is what will get it there too

Yeah, there’s nothing really exciting in the mobile space this year (so far)…except Strix Halo.
. Frankly, the 7640u handles my devel- and VM-heavy workflow perfectly 
, but FOMO is a powerful driver (not out of the woods yet 
).
