Zen4 Phoenix APU crosses 14.8K points in Cinebench R23
AMD’s unannounced 8-core Ryzen CPU is fast.
The Phoenix Zen4 platform might not have been released yet, but officially or not, we already know about at least three series based on the same silicon: 7040H, 7040HS and 7040U. AMD has not shared a word on their upcoming 7000U low-power series, but such CPUs are undoubtedly coming.
At least two SKUs have now been spotted during tests: Ryzen 5 7640U and Ryzen 7 7840U as today revealed by a Chinese source. The former is a 6-core variant while the new part features 8 cores and 16 threads, just as many as premium 7040HS parts.
The Ryzen 7 7840U shouldn’t be much different than the models with higher TDP. And yes, it is the power limit that makes this part so interesting. It is allegedly designed to operate within a 15W to 28W envelope, enabling new possibles for Zen4 through next-gen lightweight systems.
A Cinebench R23 multi-core test score has been shared for this part specifically. It shows a base clock of 3.3 GHz, but there are no details on the boost frequency. The APU scored 14825 points, which puts it above parts such as Ryzen 9 6900HX and right below i7-12800H, both considered high-end gaming CPUs from last-gen series.
The same leaker further reaffirms that the 7840U APU scores around 700 points in Cinebench R20 single-core, 3000 points in 3DMark TimeSpy Graphics and FireStrike at 8000 points (those are built-in RDNA3 iGPU scores).
Officially, the Ryzen 7040U series does not exist yet. Thus far, AMD only confirmed it will launch 7040HS laptops next month, which is a one-month delay from what was announced at CES 2023. The 7840U part might be very interesting for handheld gaming systems, should these companies decide to use it.
