Oh... 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.

- brucethemoose2 3y agoBut low power/idle efficiency will be awful using the desktop Zen 5 CCDs, if they are anything like the 7000 series. They are optimized for high clocks, and the interconnect burns tons of power, especially with 2 CCDs (which reach into each other's L3 over the link).
- wmf 3y agoDesktop 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.
- brucethemoose2 3y agoBut the Zen 5 CCDs will presumably be the same. If AMD used a single Zen 5C or 4C CCD, I would be more optimistic... Even though AMD didn't differentiate the cores, the 4000 series and 5000 seres were essentially Zen 2C and Zen 3C. But 2x Zen 5 CCDs suggest they are going for all out performance.
