AMD Ryzen 5 7640U "Phoenix-U" APU with low power consumption spotted on Geekbench

The Ryzen 5 7640U first appeared in AMD’s own marketing material before a Zen4 part was even released. AMD had used this SKU to demonstrate its new naming scheme for the next-generation Ryzen 7000 series. The “4” in the product name stands for the Zen4 microarchitecture and the “U” confirms that it is a power-saving component for laptops.

Today, a new leak was found on a Geekbench page that shows exactly this processor model. It was tested on AMD’s reference and validation platform called “Mayan-PHX”. Since this is not a retail product, one could assume that the Ryzen 7040U series is simply not ready for the market 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 3.5 GHz and a boost of up to 4.89 GHz. Furthermore, this mobile APU will be equipped with Radeon 760M graphics, so in this sense it is a 7640H(S) with a lower TDP and clock frequency.

A quick comparison with the last-generation Ryzen 5 6600U “Rembrandt-U” part 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. However, you also have to keep in mind that the leaked value is compared with the best 6600U value that can be found on the Geekbench website here. AMD has not yet confirmed the full specifications of the Ryzen 7040U series, but you could expect at least one more SKU with 8 cores. This CPU would definitely be one of the most interesting “APU “s for handheld consoles.
