Is there any info about idle power? I think that's what interested me the most from this product. I expect worse than Strix Point but much better than the Range ones.

It's an unimpressive demonstrator.
First gen product in a new swimlane, lots of low hanging fruit.
It's barely better than the preceding solution and comes with many downsides (cost, Radeon GPU).
Cost is similar to similar performance parts with weaker CPUs. And yes RDNA3.5 is only so-so, RDNA4 would've made it a class leader.
But at least it can scale up and down more efficiently.
And it will only get better.
It is not promising. Fancy new IOd didn't save Zen 5
Except it lacks a lot of Medusa IOD features.
and Zen 6 is an even smaller IPC upgrade.
We shall see, probably but clocks should finally get out of the 5.1Ghz slump.
And unlike Strix Point to Medusa Point there isn't going to be a big change from this CCD to Zen 6 CCD.
The Z6 CCD is general is way faster and N2 is no joke vs N4P.
Yes it will be against other N2 parts, so it depends on how others execute.

So I think it is ok, but obviously a regression, as the laptops with a 14" (so a bit higher display power consumption than 13") are doing better. It is a good result considering the technology it uses, but not great. It means if AMD intends to use a similar packaging technology for all their 2027 laptop chips (which it's what I understand will do) it means battery life will never be great at this rate, it will be merely good.

It's consuming 70W while matching in gaming performance the 13900H + 4070 mobile that consume over 50% more power, and there's no 8GB VRAM limit.
The closer integration also enabled Asus to put in there a 25% larger battery while reducing the weight by 80g.

And I'm pretty sure the 13900+4070 aren't even going to work at 25W total package, let alone performing above the level of a Strix Point.


This means you can comfortably take the Z13 Halo on a bus/plane trip and play games for over 2 hours before needing a wall socket, whereas the older 4070 model wouldn't last 1 hour.
100W isn't "over 50% more" than 70W.

In terms of raw gaming performance, I just don't see the appeal of strix halo over a traditional gaming laptop.

The lower power draw and better battery life is definitely a plus. I won't argue there. But most people aren't going to tinker with power limits.

It makes sense from a performance per watt standpoint. Makes zero sense from an economic sense.

At least for the ROG Flow, it seems to have a significantly cheaper launch price than the Intel+4070m model it's replacing while being lighter weight, having a slightly faster screen, and having a larger battery and better battery life. Unless I'm missing something. . .

What you are missing is that Strix Halo will only be used on very expensive devices.
So it will be put on 2000$+ laptops that will compete against 1000-1300$ 4070 laptops.
This chip is expensive, or at least AMD will sell it very expensive + the motherboard needed and all that stuff. There is no realistic market for 1500$+ handhelds, outside very niche people.

Why do you say that? There's no reason why AMD can't put cut down Strix Halo in $1000-$1500 laptops.

On the contrary, this chip makes full sense for larger handhelds like the AYANEO KUN or the Legion Go.
People were expecting this to perform badly at 40W, but at 25W it's already outperforming Strix Point and at 35W it performs well above anything we've seen.
A 13900H is old as all heck and on a significantly older node, that's a very low bar to beat. It'd be much more appropriate to compare this to the many Strix Point + 4060/4070m implementations that are no doubt floating around.

To only have noticeable gains at power limits that are at the edge of what's acceptable for handheld sizes with battery life (I. E 50-60Wh batteries) for significantly higher costs most likely kills any gaming handheld implementations with this SKU.

Look at Returnal benchmarks

It blows the competition away

I thought the consensus was that it will use N3P?
Things have changed, N2 is cheaper than expected, timing and yields are good.
Basically N3 is just like 20nm, the last gasp of an xtor tech with too limited benefits, N2 is better perf/$ vs N3, nothing else has to be said.
So outside of mono mobile parts aka the KRK replacement, everything is moving to N2.
Medusa SoC tiles are N2 even, well Halo should have a 3D tile with N2 up top and either N3P or N4C below.
Desktop is N4C IOD presumably.
RDNA5 is the tricky one, that was roadmapped for N3P in the 2023 redefinement as they were all planned to be mono parts but things might've changed there.

Because Strix Halo, by virtue of its die area + multiple die packaging probably costs at least twice what Strix Point does for AMD? And we know Strix Point SKUs are by and large not cheap. And that's before the additional margin AMD will need to compensate for the significantly reduced volumes this will have versus SP, AMD does not put in R&D for such a specialized product to get lower margins than their more 'vanilla' dies in SP&HP.

I wouldn't doubt this is largely true as AMD has marketed this as a clear halo part from the beginning, but that doesn't mean that it is an expensive chip relative to the competition in similar models. In fact, based on the ROG Flow prices, it seems that it is cheaper than the competition at similar performance. Whether AMD wants to put their Halo part in cheaper models will be up to them and their partners for branding purposes.

The fact that Asus out of all brands is selling this much cheaper than their old Intel+Nvidia combo shows that Strix Halo has a decent price point. That Z13 carries both form factor and Asus tax, yet it still hits the $2000 mark.


Look at this, it ain't even funny:



Now, whether AMD has the volumes to push Halo in anything but the premium device market... that is indeed a big question mark.

Strix Point + a 4070 = ~5% less die area than Strix Halo but with Strix Halo you don't need the additional VRAM, separate cooling for the GPU, or PCB routing and PMIC for the GPU. You also get 16 full Zen 5 cores versus 4 Zen 5 + 8 Zen5c cores in Strix Point. So ultimately, I doubt Strix Halo is more expensive for partners than a Strix Point + NV solution at the same performance level. The main difference is that Strix Halo probably won't scale well beyond 100 W like the discrete solutions will but that just means that they won't compete in DTR type systems which I don't believe was ever AMD's intention here.

Presumably Hawk/(Arrow?) + 5070 Ti/5080 would be much faster in games (and although also very pricey) comparable in price.

There will be cheaper strix point devices. Strix Halo with one CCD shouldn't cost appreciably more to produce than a 4070 mobile plus CPU.

And no, they do not need to increase the margin to "compensate for the reduced volumes". The most profitable price point is the same regardless of whether they have $100 million in upfront costs or $100.
