What's with the doom and gloom?

Strix Halo failed to get more than 2 design wins on mobile devices, one of them belonging to an extremely niche "gaming tablet" market.


It is the very first CPU model for an entirely new socket. It will take time for ODMs/OEMs to adopt it.
(Edit,) there haven't been many quad channel memory mainboards for laptops before from which ODMs can evolve Strix Halo designs, have there?
It's not a problem of designing a motherboard for that socket.
There's no shortage of NUC systems with Strix Halo. From a quick glance, there's:
Zotac
Ling Long
GMKTech

Still orders of magnitude over a fugly tablet going for $2K.



This again...

The ROG Ally X has a 80W.h battery, cooling engineered for 30W TDP and weighs 678g.
The ROG Ally has a 40W.h battery and weighs 608g. Chinese phone makers are getting 28W.h batteries inside 200g phones.

Battery capacity under 100Wh for laptops and gaming handhelds is mostly a decision based on cost, not weight or volume.




You know what else was incoming until it wasn't? Navi 4C.
If Strix Halo fails to move the needle in getting high end design wins for AMD, Medusa Halo will be cancelled.
NOooo you can't do it

Strix Halo was meant for 60watts

You are not supposed to run it in 25 watts handheld mode

The "under 100w" capacity limit is almost entirely rooted in the FAA/NTSB guidance/regulations that essentially bans mobile devices from passenger cabins if they have a 100w/h battery or larger on commercial aircraft. Physical size hasn't been an effective limitation for traditional laptops, for batteries, in a while.

Now, ultra-thins and handhelds do face packaging challenges, but recent battery tech can get them 99 watts in some surprisingly small form factors. It just gets expensive quickly.

Most of them using exactly the same mainboard.

It's going to take time for others to enter the market, if they ever do.

The Halo chips and accompanying memory are having bigger physical footprint, what in turn means they require bigger cooling solution, that will require bigger enclosure. The power circuit will have to be more robust to be able to handle the spikes in the draw, as while some Youtuber can set TDP to 30W, I guess he did not do a proper power analysis to see what are the spikes, how a smaller power stage could handle them etc. Point is, this all adds to weight. Using Rog Ally X as a proxy is bad example. As you cannot replace Z1 Extreme with Halo chip and keep everything else the same. It will not fit.

The tablet looks reasonable. Either way it would be to heavy for prolonged gaming session to keep it in your hands, and if you place it on a stand then why does it matter if it is a handled or a tablet with better cooling headroom.

Nope.

You do understand that a 60W part needs cooling and stuff?

Point was the 80W.h battery wasn't going to make it past 1Kg, and it still stands.


And the additional cooling, plastic enclosure, longer PCB and beefier VRMs won't amount to over 320g.
This thing cools up to 95W and weighs 230g, 90mm fan and mounting screws included.


By all means, feel free to share sales numbers for the ROG Flow Z13 tablet surpassing the ROG Ally, ROG Ally X and Legion Go.

Create eyewear display for it and use VR controllers. Play games on a 100 inch screen! The actual tablet/base unit can stay in a well-ventilated carry bag. That would also allow using a bigger battery, possibly up to the allowed 99 Wh.

Its also 2 times thicker than any handheld.

Have you modeled the hypothetical volume for a halo-based $1499 SRP gaming 'handheld'?

At the extreme, the below is also possible

https://onexplayerstore.com/collect...s/x1?variant=47713400488230&sscid=51k8_shl1y&

This X1 is $1,100 for the standard bundle with the controllers and magnetic keyboard.

The sad part is that all of this could be moot if AMD would just spin a version of Strix Point on N3P with a 16MB Mall cache for the iGPU. It would easily split the difference on those charts while still being in the same power, size and thermal window of the existing Strix Point part. Go back to the original design without the NPU to save die space even. Throw in a little fin-flex and it would probably surprise a lot of people with what it can do.

They already spent a lot trying to get Strix Halo out so don't think they will spend even a penny more on something similar. They are sticking with Strix Halo and someone on overclock.net was saying that Strix Halo is coming to desktop too. I guess it must have the ability to work without on-package RAM and since EXPO 8000 is a reality on desktop, they figure it's good enough. Also, many folks must've requested them for additional features like being able to overclock both the CPU and GPU cores. That would only be feasible on a desktop where users can slap an AIO or custom liquid cooling on Strix Halo and post new records.

G.Skill releasing the DDR5-8000 128GB kit? I think that's part of the equation.

I agree it isn't a problem of designing a motherboard, it is that cooling in a laptop form factor is a big problem with most of the lineup listed with TDP up to 120W. They'll either need an extreme (and therefore loud) cooling solution or they'll have to configure the TDP lower which will mean sacrificing performance - when performance is the main reason people would want a Strix Halo in the first place.

Honestly it seems like something that was more targeted at the NUC/all-in-one market rather than the laptop market. I doubt AMD is too worried about the lack of laptop design wins.

I dont see it coming to desktop, though that could be a hella cool chip if it did and was given a 170W TDP.
