AMD has made some cuts to its Ryzen 7040 series mobile processors

At CES 2023 this year, AMD launched three Ryzen 7040 series mobile processors, including the Ryzen 9 7940HS, Ryzen 7 7840HS, and Ryzen 5 7640HS. The processor code name is Phoenix, which uses Zen 4 architecture for the CPU and RDNA3 architecture for the integrated graphics. Unlike the top-of-the-line Ryzen 7045 series with up to 16 cores and two CCDs, the Ryzen 7040 series focuses on integrated graphics, with 12 sets of RDNA3 architecture CUs for a strong graphics performance.

After the CES 2023 conference, AMD launched the specific product page for the processor, which showed that both the Ryzen 9 7940HS and Ryzen 7 7840HS used the Radeon 780M integrated graphics with 12 complete CUs, while the Ryzen 5 7640HS used the Radeon 760M integrated graphics with 8 CUs. However, at that time, the product page showed that the boost clock of the integrated graphics could reach 3GHz, which was quite exaggerated. But now, AMD has lowered it by 200MHz. The specific data is as follows, and the H series has also been cut:

Ryzen 9 7940HS: 3.0GHz→2.8GHz

Ryzen 7 7840HS: 2.9GHz→2.7GHz

Ryzen 5 7640HS: 2.8GHz→2.6GHz

The reduction in integrated graphics frequency will definitely have some impact on performance, but it is difficult to determine the exact impact as these processors have not yet been released. It is expected that corresponding laptops will be available as early as March. However, the TDP of AMD’s HS series processors ranges from 35W to 54W, and processors with this power consumption will generally be paired with discrete graphics. The integrated graphics performance will not have much impact, and AMD is likely doing this to improve laptop battery life and reduce heat generation. Whether this is the case or not, AMD has not yet announced.
