The gaming industry is once again buzzing with excitement as both Nvidia and AMD intensify their rivalry. In collaboration with Dell, AMD has unveiled the RX 7900M, its fastest-ever mobile GPU. The RX 7900M promises to compete with Nvidia’s RTX 4080 if integrated into high-performance gaming laptops. In this article, we’ll delve into the features and specifications of AMD’s Radeon RX 7900M GPU for gaming laptops and assess how it measures against Nvidia’s RTX 4080 laptop GPU.
AMD Introduces the Fastest-Ever RX 7900M Laptop GPU: Specifications
AMD’s Radeon RX 7900M, as announced in a recent press release, marks a significant milestone as the company’s fastest AMD Radeon laptop graphics solution. What sets this GPU apart is its foundation on the RDNA 3 architecture, aimed at delivering top-tier graphics performance to future gaming laptops. Notably, the RX-7900M is the first laptop GPU based on a chipset design, specifically the Navi 31 processor, which offers various advantages over monolithic designs. AMD claims its RDNA 3 architecture delivers “next-generation performance” and “leading performance per watt.”
| Laptop GPU Model | VRAM Capacity | Boost Clock | Memory Interface | Total Graphics Power (TGP) |
|---|---|---|---|---|
| AMD Radeon RX 7900M | 16 GB GDDR6 | 2090 MHz | 256-bit | Up to 180W (Configurable) |
| Nvidia GeForce RTX 4080 | 12 GB GDDR6 | 1665 MHz | 192-bit | Up to 150W (Configurable) |
To make this advancement even more exciting, AMD has partnered with Dell to introduce the Alienware m18, the first laptop to harness the full potential of the RX 7900M GPU. This gaming laptop has a Ryzen 9 7945HX CPU, complemented by the recently released RX-7900M GPU, featuring 16GB GDDR6 VRAM and up to 180W of power. Comparatively, Nvidia’s RTX 4080 (laptop GPU) provides 12GB GDDR6 VRAM. Thus, even before considering performance metrics, the RX-7900M’s 33% larger VRAM capacity gives it a competitive edge.
AMD claims the RX-7900M is tailored for gaming at 1440p and higher resolutions. In specific titles, a performance comparison between Nvidia’s RTX 4080 and AMD’s Radeon RX 7900M shows that AMD’s GPU is 7% faster on average. Titles like Far Cry 6 and Doom Eternal, which both feature ray tracing, were included in this comparison. However, it’s important to note that the RTX 4080 outperforms the AMD counterpart in other games and likely offers superior overall ray tracing performance.
The performance battleground promises to get even more exciting when the RX 7900M GPU becomes available to the public. The performance showdown between the RTX 4080 and RX 7900M indicates that both GPUs will offer similar results. Below, we’ve compared the essential specs of both Nvidia and AMD GPUs for a clearer view:
AMD Radeon RX 7900M:
- 16GB GDDR6 VRAM
- 72 compute units
- 64MB of infinite cache
