Unannounced Zen 4-Based Phoenix Mobile Processor Reaches About 5 GHz

Benchleaks open twitter (opens in new tab) shared Geekbench 5 comparison (opens in new tab) Outcomes of the mysterious, low-power Ryzen 7000 cell Phoenix CPU (“Mayan-PHX on this case”) that have been by no means introduced at AMD’s press occasion at CES 2023. The brand new chip that includes AMD’s cutting-edge Zen 4 is named the Ryzen 5 7640U structure and an RDNA3 760M graphics engine. If Geekbench 5’s spec sheet is appropriate, the chip will reportedly include six cores, twelve threads, and a 4.9GHz accelerated clock.

The brand new chip introduced house 1,869 factors within the single-core check and eight,853 factors within the multi-core check. In comparison with the chip’s predecessor, the Ryzen 5 6600U, the Ryzen 5 7640U is 33% quicker within the single-core check and 50% quicker within the multi-core check.

For reference, we bought first page Share of Ryzen 5 6600U outcomes and their common to a single level. This earned us 1,404 factors in single-core and 5,916 factors in multi-core. This helps to watch how the chip is performing general and elements in numerous laptop computer circumstances the place the chip might function at totally different energy envelopes. Nonetheless, understand that Geekbench 5 scores will not be a really correct solution to measure real-world CPU efficiency.

AMD’s Ryzen 5 7640U is the primary U-series piece we have ever seen that includes AMD’s Phoenix design language. Mockingly, though the mannequin title 7640U was used to signify AMD’s new forward-looking terminology for its Ryzen cell processors, it was by no means introduced as an precise SKU – this was simply an instance. Or so we thought.

AMD’s Phoenix CPU design is presently essentially the most bleeding-edge of the Ryzen 7000 model. The structure contains AMD’s Zen 4 structure operating on TSMC’s 4nm manufacturing node, the smallest lithograph ever dropped at Ryzen. It’s also the one design to incorporate AMD’s new Radeon 700M sequence RDNA 3 structure built-in graphics models, offering a wholesome improve over earlier technology RDNA 2 options. Furthermore, Phoenix is ​​the one Ryzen 7000 design out there right this moment with non-obligatory assist for AMD’s Ryzen AI engine.

The one chips AMD has introduced up to now within the Ryzen 7040 class are the HS SKUs, together with the Ryzen 9 7940HS, Ryzen 7 7840HS, and Ryzen 5 7640HS. All of those have TDPs of 35–45 W. In the meantime, AMD’s Ryzen 5 7640U appears to be like set to be one of many first Zen 4 Phoenix-class chips to have a TDP of 28W or much less, because of the “U” sequence nomenclature.

If Geekbench 5’s numbers are much like any real-world efficiency figures, this chip will probably be a major improve over the earlier Ryzen 5 6600U. AMD’s Phoenix-class CPUs are scheduled to debut this yr, alongside different cell designs just like the Rembrandt-R, Barcelo-R, and Mendocino, so we must always see 7640U-equipped laptops very quickly.
