AMD introduces Ryzen 7040U Series chips with ultra-low power consumption

AMD has unveiled the Ryzen 7040U series of energy-efficient mobile chips powered by the innovative Zen 4 architecture and RDNA 3 graphics. However, the new chips are exclusively designed for thin laptops.


Earlier this year at CES 2023, AMD announced the first wave of the Ryzen 7040HS (Phoenix) series mobile processors with Zen 4 architecture and RDNA 3 graphics which were to be used in powerful gaming laptops. 

Expanding its 7000 series mobile processors, AMD has now introduced the Ryzen 7040U series, energy-efficient, mobile chips. The U in the Ryzen 7040U series stands for “ultra-low power”, meaning the Ryzen 7040U series processors’ USP provides high graphics quality on low power consumption.

The latest series includes the following three chips:

  • AMD Ryzen 3 7040U series
    • The new Ryzen 3 7440U houses four cores and eight threads, a 3.0 GHz base clock, and a turbo frequency of 4.7 GHz. The chips’ TDP display is dynamic and can be configured in the range of 15 to 30 watts.
  • AMD Ryzen 5 7040U series
    • The duo of Ryzen 5s, the 7540U, and 7640U, provide six cores and twelve threads, with base clocks of 3.2GHz and 3.5GHz respectively. Both chips pack 22MB of L3 cache memory and a turbo clock speed of 4.9GHz.
  • AMD Ryzen 7 7040U series
    • The top-tier Ryzen 7 7840U impresses with eight cores, sixteen threads, a 3.3 GHz base clock, and a boost clock that reaches 5.1 GHz. This model is equipped with 24MB of L3 cache memory.

Each of these processors features an integrated Radeon 700M GPU, with distinct compute units and top speeds for each model. The Radeon 700M line is powered by the same RDNA3 architecture found in the Radeon RX 7000 desktop graphics cards. Also included is the Ryzen AI Engine, an XDNA architecture-based FPGA developed using Xilinx technology, designed for specialized computational tasks.


With the latest “Zen 4” CPU cores and RDNA3 graphics, based on the 4 nm “Phoenix” monolithic silicon, the Ryzen 7040U series is a game-changer as it outperforms its competitors. This new series provides up to 139% faster GPU performance than the Intel Core i7-1360P “Raptor Lake-U” processor and 75% faster CPU performance than the Apple M2 SoC.

However, AMD did not test the performance of its highest-end chip AMD Ryzen 7 7040U against Apple’s latest highest-end chip, M2 Max. The M2 SoC is the first build of the M2 series chips.

Windows laptops based on Ryzen Mobile 7040U series processors will be available in the market starting next quarter. Some PC makers have already begun to announce plans to release laptops with the new chips.
