AMD Radeon RX 7900M

The AMD Radeon RX 7900M stands as a high-performance mobile graphics card, built upon the Navi 31 chip utilizing the RDNA 3 architecture and crafted with a 5nm manufacturing process. This GPU boasts 4,608 cores distributed across 72 compute units (CUs) and is equipped with a swift 16 GB GDDR6 graphics memory, connected through a 256-bit memory bus. Additionally, it integrates a 64 MB Infinity Cache. The core clock speed is variable, contingent on the specific laptop configuration, with a specified game clock speed of 1825 MHz (likely at a 180 W Total Graphics Power, or TGP).

In direct performance comparisons, AMD positions the 7900M against the mobile RTX 4080, showcasing an average 7% speed advantage across various games. Notably, the 7900M supports hardware-based ray tracing, albeit often at a slower pace compared to its Nvidia counterpart. Nvidia gains an edge with its DLSS (Deep Learning Super Sampling) support in select games.

The Navi 31 chip is manufactured by TSMC using the current 5nm process. The power consumption, denoted as TGP (Total Graphics Power), ranges from 160 to 180 Watts, with the potential for reaching 200 Watts when considering SmartShift technology in collaboration with the CPU.
