But the pricing there isn't based off of the GPU performance only. In case you forgot, those products also have CPUs attached to them as well. The pricing for these products will factor in both sides of the argument. The top end 800Gs were factored like they are what they are: 8 core CPUs with a competent - but not super powerful - iGPU attached. Trying to suggest APUs should be priced to compete against dGPUs is a bit ridiculous, it completely ignores half the product.
Everybody, Print it, hang it above your bed, so that you could see it every morning and evening, and remember that APUs are going to be priced based on CPU AND GPU performance. Not just GPU.

When you understand this, you will see how incredible deal APUs are, or can be compared to standard hardware.

I think the 120W TDP is the case when both the CPU+GPU are fully utilized (not in the Flow z13's case, but a hypothetical mini PC or large workstation laptop with sufficient cooling split in 55W+65W for the SoC) Thoughts?
Indeed.

Intel might actually do well next year. Actually out of QC and NV, it’s Intel that has the highest chance.

Cause NVL SoCs will be good. NV would be great comp but WoA needs to improve
Intel will compete only with 128 Bit chips, so not technically halo competition, however, they will have far superior product in that 128 bit bus category.

AND, on top of that Intel has sane product segmentation, where you could get binned down CPU, but with Full GPU config. AMD cuts the GPU before it cuts the CPU.

VERY curious to see how AMD designs future Halo products. Zen 6 is supposedly all chiplet (even on mobile) with new packaging that Strix Halo is likely testing. The set-back on GPU chiplets is unfortunate because they likely planned to share them between desktop and laptop.

My biggest question is why they’re sticking to just one GPU die on consumer products? Does it cause too many software compatibility problems or is the required packaging just too expensive? If multiple GPU dies work with silicon bridge packaging, that would give them a ton of flexibility to scale performance. Given the socket size constraints, they may need 3D stacking to fit much more silicon though.

?? no, die area is not infinite

medusa halo will look similar with up to 24 zen6 cores, optional 3d cache and as much rdna5 they can cram in, that's it

any other low power optimizations will be the result of zen6, rdna5 and advanced packaging advancements

Both. Current graphics rendering expects all graphics computing to be done in one single NUMA. To still go chiplets with computing the links between each of them would need to be able to handle the total internal bandwidth, and that's financially unfeasible in a consumer product and is the more costly the more you want to scale it up. Without that you will see dramatic slowdowns due to bottlenecks, kind of akin to Zen's CCX to CCX latency but much worse since no software is prepared at all for something like this to happen. The result would be lower framerates for two compute chiplets than for one.

I still hope there will be a solution to that conundrum sometime. But AMD for some reason doesn't appear to want to push for the required rendering software changes (Sony and Microsoft could push for it on their consoles if they wanted to, Microsoft could introduce it as part of Direct X, Vulkan could be prepared and extended accordingly) and Nvidia is perfectly fine with continuing to push its moonpriced monster monolith chips onto the market.

It's all feasiable and pretty easy, the hard part is making the serial parts of your gfx pipeline (lot of them) parallel.

you can't.
No one will ever bother with anything resembling explicit multiadapter.

could they really cram 80 CUs with everything else less and like only 8 dense cores etc? 2 GPU dies doesnt make much sense for mobile devices

It's feasible and pretty easy except you can't. Good succinct way to describe the conundrum indeed.

Thats interesting, all the M4 Pro references make sense now.

With the success of Apple Silicon, Macri was finally able to get approval to spend a "mind boggling" amount of money developing the Ryzen AI Max. "I always knew, because we were building APUs, and I'd been pushing for this big APU forever, that I could build, a system that was smaller, faster, and I could give much higher performance at the same power," he said.

AMD had been proposing big APUs for mobile for years, when Apple did it PC OEMs finally realised there is a market for them.
whoever kept denying the big APU project needs to go... AMD still has bad suits calling shots
There was never enough market interest, suits are needed for final approval, but they never got that close.
