A leaker at the Asia language language language dialogue discussion board Zhihu has published an intensive efficiency research of AMD’s Ryzen Z1 processor – the little brother of the Z1 Excessive chip printed previous this three hundred and sixty five days and observed in motion in PC gaming handhelds associated with the impending Lenovo Legion Go.
David Huang posted his findings on Zhihu, giving us quite a lot of trust into how this chip will carry out with regards to lately to be had gaming handhelds very similar to the Valve Steam Deck, which runs on an older customized Zen 2 APU from AMD. He supplied detailed specifications and function stats, together with fairly a couple of recreation benchmarks, although we will be able to should warning that we will be able to’t check out that those are unique effects from the CPU.

Even supposing Huang didn’t have a Z1 Excessive at hand for direct comparisons, he did examine efficiency to AMD’s Ryzen 7 7840U computer CPU that used to be printed previous this three hundred and sixty five days. The 7840U used to be possibly made up our minds on since it’s broadly analogous to the Z1 Excessive chip when it comes to not unusual specifications (although exact efficiency varies, for the reason that Z1 APUs are specifically designed for use in hand-held gaming gadgets).
As for the consequences? Neatly, they are just a little of a mixed bag. The usual Z1 clearly lags in the back of its Excessive counterpart in gaming efficiency, nevertheless it definitely’s additionally much more power-efficient – providing a playable revel in at 720p with simply 15W of power intake. Dialing up the to be had power draw to the chip’s most of 30W in reality handiest supplied a modest efficiency spice up of lower than 20% on inexpensive.
Naturally, the Z1 is anticipated to be a very good bit somewhat priced than the Z1 Excessive – although it is going to now not be in the stores immediately, so pricing will in spite of everything be decided by means of the third-party producers the usage of the chip.

Ultimate three hundred and sixty five days, my colleague John Loeffler published a work about the possibility of Apple’s M-series silicon for gaming in included graphics. Whilst I respectfully disagreed together with his stance about macOS turning into a gaming haven (OK, excellent, I discussed I’d fairly die than turn into a Mac gamer), John used to be utterly correct that processor-integrated graphics would be the means maximum other people play video video video games someday.
Believe, for a 2d, the RTX 4090. Nvidia’s flagship desktop graphics card is an absolute monster, costing greater than 3 PS5s and guzzling down as much as 450W of power (with out overclocking). That’s 30 instances the utmost power intake of the AMD Z1 operating at 15W – and as well as you’ll want some in a similar way power-hungry portions for your PC to stop your 4090 from bottlenecking, too.
In an technology the place electrical persistent expenses can be brutal (in particular if, like me, you are living in the United Kingdom at the moment), low-power gaming is instantly preferable. The rush for gaming-capable iGPUs is handiest simply starting; now, each and every new technology from primary avid players together with AMD, Intel, and Apple brings spectacular efficiency leaps. The opposite benefits are measurement and thermal efficiency; those chips can be with ease squeezed into compact gadgets like gaming handhelds and the easiest imaginable ultrabooks.
Even supposing there are not any unswerving main points at the moment about gadgets that may use the Z1 chip, it’s very in all probability that lately to be had handhelds the usage of the Z1 Excessive will see a somewhat priced variant pop up all over the not-too-distant long term. Once I met with Lenovo in Berlin at IFA 2023, the team of workers had been coy about the possibility of a further reasonably priced Legion Go, alternatively all alternatively showed {{{that a}}} Z1 sort would arrive in spite of everything.
In my opinion, I will’t wait – and I’m hoping that AMD is making plans a Z2 assortment to ship even higher gaming efficiency with the an an identical low, low power draw. If handiest Microsoft would in all probability merely get their act in combination and provides Area house home windows 11 a right kind hand-held mode…
