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