Ryzen 5 7640U spotted in benchmark, with single-core performance leading Ryzen 5 6600U by around 34%
According to previous reports, AMD released the Ryzen 7040/7045 series mobile processors based on the Zen4 architecture at CES 2023. However, only information about processors with the suffixes HS/HX was disclosed, and the U-series processors with lower default TDP were not mentioned. Recently, Geekbench leaked benchmark scores for the Ryzen 5 7640U.
The test system used was Windows 11 Pro, with the power mode set to balance, and the test software was Geekbench 5.4.1, which is not the latest Geekbench 6. The single-core score of the Ryzen 5 7640U was 1869 points, and the multi-core score was 8853 points, with the processor reaching a maximum frequency of 4.9GHz during the test. For reference, the single-core score of the Ryzen 5 6600U is around 1400 points, and the multi-core score is around 6500 points. The Ryzen 5 7640U showed an improvement of 33.5% in the single-core score and 36.2% in the multi-core score. The performance improvement brought about by architecture advancement and frequency increase is quite significant.
Currently, AMD has not officially disclosed the specific parameters of the Ryzen 5 7640U, but the parameters of the Ryzen 5 7640HS can be found on the official website. Combined with some information provided by Geekbench, some parameters of the Ryzen 5 7640U can be roughly inferred. U-series processors are generally used in lightweight laptops with not particularly high-performance requirements. The lower power consumption setting can provide longer battery life.
The previous-generation Ryzen 6000 series mobile processors performed well in terms of energy consumption ratio. The U-series mobile processors with Zen4 architecture are expected to provide even better energy consumption ratio performance.
