#2In terms of IPC @ GB6, with an expected ~20% gain from Zen 4, Zen 5 still need another 15% improvement before it catches up to A16.
But it will be interesting to see any write up on the benefits of using Zen5c ( Cache scaled down version of Zen 5 / P-Core ) instead of using a smaller but different uArch E Core as in Intel and ARM are doing.

#3Oh... That is disappointing.
I was hoping Strix Halo would be a big, power efficient, Apple M-esque SoC with a wide iGPU.
The 16x Zen 5 cores (with no efficiency cores) and the "sharing" of the desktop architecture suggest its actually a Dragon Ridge 7045HX replacement. So a power hungry CPU for 17" desktop replacement laptops you can basically only use while plugged in... That has a large IGP for some reason? That doesn't make much sense, as you mind as well use the dGPU.

#4I'm surprised that WCCF tech is getting on the HN front page. They are known for just running with any inkling of a rumor, or even just jumping to their own wild conclusions and running articles on that.

But maybe the goal is to finally offer an H class SoC that doesn't need a dGPU?
RDNA 3.5 with up to 40 CU should be well into Apple SoC Pro/Max territory.

Desktop Zen 5 (Granite Ridge) is 128-bit while other rumors said Strix Halo is 256-bit so if that's true they aren't the same. I suspect there will be three or four different laptop Zen 5s (baby, regular, halo, and desknote) so this article is probably just incomplete.

#9Does the word 'Strix' have some sort of computing relevance that I am unaware of or is it really just a cool sounding name for a genus of owls? Because Asus uses this word in products too and I've never known if it was supposed to relate to something.

Granted that it is too early to know, but I like the AMD approach. If I’ve understood correctly, the c-cores have absolutely identical functionality on all fronts. They can’t clock as high due to the layout being redone to optimize power & area, and they lack some cache vs the high-power cores.
So essentially, any core should be able to handle any workload but you’d bias single-threaded tasks onto a few 5 GHz (or whatever) capable cores. And if you’re running well-threaded code across many cores, they’ll have to slow down anyway to stay within the power envelope, at which point all are effectively identical, barring the extra cache.
Only question is whether Intel saves a lot more power & area with their (IMHO crippled) efficiency cores. If they do, it ought to give Intel a cost/price advantage.
