AMD Radeon RX 7900M “Navi 31” Laptop GPU Beats The NVIDIA RTX 4080 “AD104” In First 3DMark Tests
The first AMD Radeon RX 7900M "Navi 31" GPU performance tests are in and it beats the GeForce RTX 4080 laptop GPU in 3DMark Time Spy.
The AMD Radeon RX 7900M was first leaked by us back in early October and it made its official debut last as a part of the Alienware m18, the only AMD Advantage and all-AMD laptop design to feature top-tier Radeon GPU & Ryzen CPU hardware. Prior to that, AMD's RNDA 3 lineup was quite lacking with only Navi 33 GPUs serving the entry-level and mainstream segments.
Both AMD and NVIDIA usually launched GPUs one tier below the desktop flagship as the top mobile SKU and even those were further spec'd down, either in terms of core configurations or clocks/power. With the Radeon RX 7900M, AMD not only brought the world's first chiplet GPU to the laptop segment but also offered its flagship Navi 31 chip on the laptop segment, something that even NVIDIA has been unable to do due to power/thermal constraints.
AMD Radeon RX 7900M "Navi 31" GPU Specifications
The AMD Radeon RX 7900M GPU is based on the RDNA 3 graphics architecture and features a total of 36 WGPs or 72 Compute Units which make up a total of 4608 cores. That's 20% more cores than the 7800 XT & 10% lower cores than the 7900 GRE. Clock speeds for the GPU peak out at 2090 MHz.
In terms of memory, the GPU is equipped with a total of four MCDs which will enable a 256-bit wide bus interface & 16 GB memory capacities. That will get AMD on par with NVIDIA's top RTX 40 offerings such as the RTX 4090 which max out at 16 GB memory too. As for the power numbers, the AMD Radeon RX 7900M will be configured at a TGP of 160W & can be pushed up to 200W with SmartShift technologies.
RX 7900M is 7% faster than the RTX 4080 laptop on average.
