I wonder if drivers are ISV certified (Solidworks, Autodesk etc.)?

Because when I look at the prices this is actually good value. 64GB version is not that much more expensive compared to 16" models with RTX A2000 8GB gpus (HP ZBook Power G11 A 16”). And this 14" has OLED screen, faster processor and GPU should be faster than RTX A2000.

In fairness, it will run using a lot less than ~60W. Given past Zen products it would still likely keep a lot of the performance it has at those lower power settings as well.

It's just not worth putting such a large die into that kind of package. I'm sure modders will make a few, but it's not something that would make for a mass market product.

The PC handhelds users are very elitist.

Halo is not for handhelds and frankly no AMD APU is currently, not until that Sony 3nm SoC comes out that is. 10-15 watts is the sweet spot.

The PC handheld market is TINY. AMD is better off allocating to other better users that will make use of Halo.

Still cheaper than a lot of crappy 5090 laptops that won't be able to handle tasks requiring more than 24GB VRAM.
But those "crappy" 5090 laptops are meant for gaming and they will annihilate Strix Halo easily in that regard and Halo also has a big disadvantage in using RDNA3 instead of RDNA4, which would be much more preferable for gaming.
If you want to play with AI, then yes, Strix Halo with 128GB is what you should chose.

BTW, I expected this HP to have higher power limits than Asus, but It's actually the opposite.

HP from what I remember was always very conservative with power limits (especially with 1T workloads for some weird reason) and since this is a business line they want to play it safe anyway, I would guess.

There is no problem even with 25-30W, I wouldn't mind even more If It can be cooled effectively, but this can be used only when plugged in or docked. Only the "handheld" mode is a problem because of short battery life even with big batteries.

Actually, Strix Halo would really provide the best performance for handhelds, but too much performance would be lost by limiting It to 15-25W, so not worth the effort and cost.

But If AMD made a custom monolith 8C16T Zen5c + 16CU RDNA4 APU + 16MB IC(SLC) for Valve, that one could be relatively powerful even with limited power.

As Cary Golomb says the main driver for a handheld is 4 channel memory & 256bit bus

If you have those two then you can game 2d games at 7w & 720p at 15w & 1080p at 25w & docked at 40w. All this on a 80 watt battery like the rog ally x

Only issue is this is a premium product (like kaby lake G). AMD is not producing a cut down version tailored for handhelds. That is why they are marketing more towards AI

It's not a goddamn handheld product just full on stop.
256b parts do NOT belong in any handhelds.

256-bit is 8 channel memory, because the width is 32-bit max per chip with LPDDR5(X).

A custom chip could go even with a compromise of 192-bit bus and 6 memory modules to mitigate BW bottleneck or big SLC. You could still go as high as 96GB with 128Gbit modules.
But the issue except the higher cost would be space. Picture of Asus Rog Ally PCB.


edit: Handhelds are already pretty expensive, so I don't expect any custom chip with more than 128-bit bus.

I love my deck and legion go but like come on, nobody is going to pay the extra BOM for like 5-10 fps. Putting all that potential into a device just to limit it to like 1/3 it’s tdp and potential is so dumb. I don’t know why phawx is so obsessed with this idea, it just seems like it’s for the sake of making content.

He wants Microsoft/valve to order a custom apu/soc from AMD modelled on strix halo

Why focus on dis-aggregation? If it's for a handheld it'll have a lower TDP meaning it would best be equipped with fewer CPU cores, fewer WGPs and smaller memory bus meaning it could easily be monolithic again. Then what would it have in common with Strix Halo?

For Valve, even 6 Zen 5 CPU + 6/8 RDNA4 WGP would be a big upgrade.
