Nvidia GPUs energy the overwhelming majority of gaming PCs, however for extra built-in recreation methods like consoles and handhelds, AMD’s means to supply tightly built-in Ryzen CPUs and Radeon GPUs has earned it many shoppers (and plenty of income). The most notable of those is Valve’s Steam Deck, which mixes a Zen 2-based CPU and RDNA 2-based GPU cores to offer satisfactory efficiency for many video games.
Though AMD designed the Steam Deck’s chip solely for Valve, at this time, the corporate is asserting a pair of Ryzen chips aimed on the rising variety of Steam Deck-esque handheld PCs from different corporations. The Ryzen Z1 and Z1 Extreme (respectively) mix 6 or 8 Zen 4-based CPU cores with 4 or 12 RDNA 3-based GPU cores, utilizing AMD’s newest architectures and a 4 nm manufacturing course of to outrun the Steam Deck’s APU.
The Z1 and Z1 Extreme are new APUs made particularly for handheld gaming PCs just like the Steam Deck.

AMD says (by way of The Verge) that the Ryzen Z1 can run video games about 55 % sooner than the Steam Deck, reflecting the improved efficiency and effectivity of the newer architectures and manufacturing course of. Interestingly, the Z1 Extreme’s further GPU cores (12, up from 4 within the Z1) enhance gaming efficiency, however they do not come anyplace close to tripling and even doubling it. The further {hardware} helps, however we’re nonetheless coping with built-in GPUs right here, hooked up to a comparatively sluggish pool of DDR5 that they share with the remainder of the system quite than devoted GDDR6 or GDDR6X reminiscence.
The specs of the Z1 chips seem much like a few of AMD’s upcoming Ryzen 7000U processors for ultrabooks and thin-and-light gaming notebooks, however AMD says the Z1 chips use “custom-made energy and voltage curves” and “different variations” that make them better-suited for handheld methods.
The Z1 Extreme has thrice as many GPU cores because the Z1, however reminiscence bandwidth limits imply that efficiency would not scale linearly.

The Ryzen Z1 chips will initially energy the Asus ROG Ally, an upcoming handheld gaming PC that Asus confusingly determined to announce on April 1. Many corporations use April Fools’ Day as an excuse to make “humorous” prank bulletins, and Asus needed to reassure folks after the actual fact that “it is actual” and was “not an April Fool’s [sic] joke.”
AMD says that Asus will announce extra in regards to the ROG Ally on May 11. AMD’s efficiency numbers are all from a ROG Ally prototype working in “Turbo Mode,” which permits the APU to attract as much as 30 W of energy; modes that minimize efficiency in favor of higher battery life might not carry out as effectively.
Though Ryzen Z1-based handhelds ought to be able to sooner total efficiency than the Steam Deck, Valve’s SteamOS should have a aggressive benefit. Other handheld PCs like the AYA Neo have shipped with Windows, which has nice recreation compatibility, however its mouse-and-keyboard-centric person interface is not an awesome match for small-screened handhelds. Some engineers inside Microsoft have examined a “handheld mode” that might remedy a few of these issues, however we do not know when (or whether or not) it should see the sunshine of day.
