Yes, and fairies will carry the bits from DRAM to SoC and back...
What if the SoC was designed with desktop use in mind? Maybe it already has the required traces. Maybe that's why it took them so long to get right. They looked at the history of RAM market and thought, DRAM keeps getting oversupplied and then prices drop too much. Most people don't need that much RAM. But what if we gave people a reason to want more RAM? An APU would be the perfect answer to that problem.

When before RAM was too much abundant, now people will WANT to use the overabundant RAM sticks floating aimlessly in the market. And AMD probably thought it's a good idea because it would be disruptive in nature and push the envelope of what's possible in personal computing when everyone has too much RAM. New possibilities may crop up sooner or later. Humanity will get closer to unlocking the real potential of computing!

No. I think the delay was caused by the prolonged negotiations with fairy labour union.

On a more serious note, assuming you were able to fit Strix Halo into AM5 package, you will be bottlenecked by 2 channel DRAM setup. Unless you are able to sell me 2x64GB sticks of DDR5 able to due 16000MT/s without hassle on existing boards.

There is a reason Framework was told that socketed DRAM won't work. They could either get the BW or socketed memory, and the BW is part of the DNA of this part.

Hypothetically dual LPCAMM2 should have given the ability to have 2x128 bit modules and modularity/socketability.

The issue as I understood it described by Framework was that there was no way to physically place two LPCAMM2 modules to get good enough signaling the way the package was designed.

Perhaps AMD can redesign the physical layout of the package and pinout next time around to bring support, but I don't think AMD cared to make that additional effort for this very much prototype-style product this time around.

Its also 2 times thicker than any handheld.
Thankfully we live in a 3 dimensional world where you can e.g. lower the height and increase width while keeping the same volume and surface area on a heatsink. Also, STX Halo doesn't need a 95W cooler.



But does not fit in a handheld. You also need to consider the noise output of the small fans in constrained space.
The AYA Neo Kun supports up to 54W TDP on a form factor smaller than the Legion Go and weighing less than 1Kg.



I am looking at the wrong thing, the Strix Halo Ryzen AI Max lineup? Because what I'm looking at says "cTDP 45-120W"
According to ThePhawx' benchmarks, it barely gains any gaming performance above 45W. I guess past a certain point the CPU cores are simply eating the iGPU's much needed bandwidth.

The 120W mode is probably only useful for pushing all those 16 CPU cores at once.

Gotta say I’m kinda disappointed at OEMs not implementing Strix Halo for more laptops. We saw no new ones at computex.

Forget handhelds, halo isn’t even coming to laptop space where it was made for.

It is the lack of Memory on Package that has severely limited its use. The "conventional wisdom" on this is just plain dumb.

- it takes a lot more effort to design a laptop mobo with 256 bit bus.
- it is far easier to implement MoP inside the CPU package than on motherboard
- AMD did not do the easier solution
- instead offloaded the hard part on OEMs
- OEMs don't like to do any hard work, especially for AMD
- conventional wisdom says OEMs don't like MoP, but every OEMs has multiple designs for Lunar Lake
- OEM hate is so much that Intel's Lunar Lake processors have secured over 95 design wins for laptops across more than 25 PC manufacturers, including major brands like Dell
- What OEMs really "love to do" (not have MoP, spend a fortune on R+D to design their own mobos) and there is 1 single laptop design win from a single OEM and 1 tablet from one single OEM

It seems quite self explanatory that AMD screwed up by not having MoP for Strix Halo. If they learn something from this and implement it for Medusa Halo, then it will still leave AMD losing 2 years of leadership. And in 2 years, AMD may get lapped by NVidia releasing Arm based high performance APU.

The argument against MoP for the product that needs it the most are just regurgitating "conventional wisdom" retardation.

AMD has undoubtly provided them whole MBs plans with all files so they can mod them at will, with current routing softwares it s a cakewalk to design any MB starting from any schematic, the time when things were hand drawn is over since decades, so that s not a matter of difficulty but rather of lazyness and lack of agressivity, you can be sure that once small manufacturers start to sell significant quantities the big names will follow suite.

How do you then explain 95 design wins for Lunar Lake vs. 2 design wins for Strix Halo?

Of the 2, only one was timely, the 2nd one (HP) was delayed, and all the MiniPCs (including HP) seem to be delayed.

If it is a cakewalk, how come only one - Asus - actually succeeded at this cakewalk and everyone else has failed in one way or another?

Then again, HP is the *only* 14" class laptop (1.57kg) in wintel land which can handle serious 3D & AI (GPU RTX 3000 level perfomance) with decent batterylife. I am evaluating this for one of my customer (architect).

According to HP certified drivers for these at least are available:

Autodesk Inventor
Autodesk Autocad
Autodesk Navisworks
Solidworks

Would like to know if Twinmotion works. Archicad probably works as it works well with consumer AMD cards,

Strix Halo is way bigger than any other APU before. It is in an entirely new category (in x86 land at least), and it is a brand-new top-end pricing tier for APUs.

Yet some people are puzzled why there is not a plethora of laptop models with it yet, and conclude that now is the time to consider it a failure.

Right.

- OEMs don't like to do any hard work, especially for AMD
They never liked to do any hard work for Intel either. So Intel did it for them.

Re MoP: Yes, it would reduce design complexity a bit, validation efforts too, but would not exactly eliminate the proverbial hard work.

Edit,
The argument against MoP for the product that needs it the most are just regurgitating "conventional wisdom" retardation.
AMD's Director of Product Management for Premium Mobile Client is on record for regurgitating "conventional wisdom" retardation too.

Not true even for x86.
Strix Halo is a 37.5*45mm, 1687mm^2 package.
Kaby Lake G is a 31*58.5mm, 1813.5mm^2 package.

Pricing was probably very similar as well. Hades Canyon barebones released for $1000, easily going for $1300 or more after including 2x SODIMM DDR4 and M.2 NVMe. That was 7 years ago, so if we include inflation Kaby Lake G was actually more expensive.


And if you count all the medium to top-range laptops with a dGPU, Strix Halo ends up being tiny in comparison.



Yet some people are puzzled why there is not a plethora of laptop models with it yet, and conclude that now is the time to consider it a failure.
It's a failure because it secured 2 (two, dos, zwei) design wins on portable devices, of which only one is an actual work laptop.
All while lunar lake secured 50x more design wins.

So yes, unless there are more laptop design wins coming up that somehow missed the CES and Computex, Strix Halo is a massive flop. At least for the B2B Marketing teams.

All i can say is that the chip retail for 550$ and that OEMs get it at 400$ at most
if not less, it s just that OEMs are not willing to release anything in big quantities,
yet there s undoubtly a significant market for such a product.

As for Asus, and HP, they released something because they are agressve when it comes to grab some high margin sales since it will be expensive as long as there s no
meaningfull competition.

At this point it s not a failure from AMD but rather from OEMs who are stuck
in old fashion mentalities, and this will likely backfire at some point because
some innovating chinese brands will inevitably catch the opportunity and fill the void.

Since I did not try to look very far, quoting a pcgamers review https://www.pcgamer.com/hardware/handheld-gaming-pcs/ayaneo-kun-review/
I also found it left the device in a rather fragile state, functionality wise. I seemed to suffer more instability and flakiness when I was switching between the 54W mode and more sensible presets. In the end I've renamed it from 'Extreme' to 'Unwise' and probably won't be using it again.
Also notebookcheck notes if you want to use 54W mode you have to bear with the noise https://www.notebookcheck.net/Ayane...rmance-beast-for-individualists.797526.0.html

So Lenovo is offering a mini pc Strix halo. My new theory is that it’s easy for OEMs to dump Halo into a mini pc and call it a day.

Laptops are different cause more of thermal, heat and noise constraints. Also battery life etc. That one HP Strix Halo laptop suffered from poor battery optimisation.

@ToTTenTranz, "bigger" in terms of CPU and GPU computing width in a single mobile package

Apropos Kaby Lake-G. Five months after it was launched by Intel, Notebookcheck wondered about the lack of laptops with it, even of announcements of laptops.

That NBC article makes another good point, Nvidia.

Strix Halo and future derivatives are competitors to Nvidias laptop SoC goals. And guess who making laptops for Nvidia later this year and into CES 2026, Lenovo, Dell and ASUS.
