The Ryzen 7 7840HS processor has a configurable TDP between 35-54W. Assuming it’s not configurable by the user, what TDP is Framework shipping these with?
The FW16 specification page indicates 45W TDP, but maybe that’s average. Engineering would need to confirm.

Idk how I glossed over that, thanks!

I agree that we need confirmation. Even if the thermal system could only take 45W continuous, there may be options of increased fan speed to push it further - and some loads, like compiling for a few dozen seconds every few minutes, do not have the same continuous requirement at all. So I truly hope the supporting power system can support up to 65W (though ofc I suspect it will be configured to 45W by default). I know some mini PCs using these chips (e.g. BeeLink GTR7 [PRO]) come preconfigured with 65W TDP, not even just 54W
The usual approach by everyone else seems to have enough power delivery to push the TDP to the max and cooling is the limiting factor. I certainly would expect the framework to be the same.
Is this really “Solved”? Has anyone seen anything official confirming what the sustained operating power limit with the cooling solution they’ve got is? Since the performance of these is very similar you’d need to be able to run the 7940 at higher power to justify the price delta I think – really need that information to make an educated assessment.
Since the original question was only asking for TDP of the 7840HS and the FW16 specification gives the TDP, it looks like solved to me.
You can certainly ask if that is “really truly” what the current stock cooling solution can sustain indefinitely, but that wasn’t the original question here. So if you want to ask that, and not have it be under a thread marked [solved], you could create a separate thread for it.

Correct, this question was specifically about what the 7840HS chip was configured with as seen by the BIOS. It’s set to 45W, which answered my question.
Personally I don’t believe the performance delta, if there is one, will be worth the additional cost. Even if Framework answers your question, you’d still want that to be verified by a 3rd party reviewer which likely won’t happen until the device is released. If it’s mission critical for you, I’d recommend waiting for reviews on your purchase. Personally, I’ve ordered a Batch 1 7850HS model.

I have to agree on that. If the 7940HS had something like 14-16 compute units on the GPU compared to the 7840HS’ 12 then I could see the price difference being fair, but $200 for a 100-200MHz boost is more than I can personally justify. The other way to look at it is that for a $200 increase you are half way to the GPU module itself, so I don’t know that even more compute units on the 7940HS makes sense.

Exactly. I’ve done the whole “performance at all costs thing,” heck, my Desktop right now has RTX 3090’s in SLI (yes, I know). Comparing how much I’ve enjoyed my Uber-desktop
and how much I’ve enjoyed my Steam Deck, I’ve come to accept that raw performance isn’t the whole equation.
If this were any other laptop, that $200 could make a little more sense, but seeing as how I can just replace the motherboard/cpu in a year or two and get a real performance difference for my money, I’d much rather play the long game. I’m speaking less to you FlyingTypeTrainer, and more sharing my thoughts out loud for anyone who stumbles across this thread.

Yep. I might be in the market for the top tier performance since I do plan to use this as a high-end VR rig eventually (with eGPU via OcuLink of course) so I don’t have to spent the same kind of money again on a new desktop platform. But even then, the 200$ is just too much considering I still don’t even know if I’ll be able to make full use of it - which depends on the Bios implementation:
TDP, per-core curve optimiser voltage offsets, etc. would all need to be adjustable within the bios itself for it to be even remotely worth it. And seeing as that is non-standard for other vendors, and Framework seem to mostly just use a customised bios from a 3rd party vendor, I’m just not sure we’ll get that.
