First AMD Phoenix-U APU has been sighted, 25% faster than predecessor
This low-power mobile processor has not yet been officially announced by AMD; however, it is not precisely a secret that such a part is planned.
The Ryzen 5 7640U first appeared in AMD’s own marketing materials before any Zen4 part was even released. AMD had used this SKU to demonstrate its new naming schema for its next-generation Ryzen 7000 series. The “4” in the product name stands for Zen4 microarchitecture and “U” confirms this is a low-power part for laptops.
Today, a new leak has been found on a Geekbench site, featuring this processor model exactly. It was tested on the AMD reference and validation platform called “Mayan-PHX”. Since this is not a retail product, one might assume that the Ryzen 7040U series is simply not ready for launch yet.
The specs revealed by the listing confirm Ryzen 5 7640U is a 6 core CPU with 12 threads, a base frequency of 3.5 GHz and boost up to 4.89 GHz. Furthermore, this mobile APU will be equipped with Radeon 760M graphics, so in this sense, we are looking at 7640H(S) with lower TDP and clocks.
A quick comparison to the Ryzen 5 6600U “Rembrandt-U” part from last gen with Zen3/RDNA2 architectures, shows that the Phoenix part will be at least 27% faster in single-core test and 22% faster in multi-core. Just bear in mind that we are comparing the leaked score to the best 6600U score we could find on the Geekbench site.
AMD is yet to confirm full Ryzen 7040U series specs, but one could expect at least one more part with 8 cores. This part would definitely be one of the most interesting APUs for handheld gaming consoles.
